Lehman Award Dr. Kate Mahaffey’s contributions to our understanding of the risk posed by metals such as lead and methylmercury date back over 30 years. Her early work demonstrated that the toxicity of lead could be modulated through its interactions with other essential metals such as iron and calcium. She extended these efforts through both clinical studies and use of the N-HANES data sets and Kathryn to corresponding risk assessments for Mahaffey lead that played an important role in the evolving regulatory decisions limiting the exposures of children to lead in the U.S. Similarly, Dr. Mahaffey has also contributed at several levels to the regulatory process for limiting exposure of women of childbearing age and children to methylmercury exposure through fish consumption. She was one of the principal authors of the EPA’s Mercury Study Report to Congress that served as the background for alerting the scientific and regulatory communities to the health risks posed by methylmercury and for identifying subpopulations at highest risk from such exposures. This award is granted in recognition of her past and continuing contributions to regulatory affairs and to risk assessment of chemical agents, particularly on the health risks associated with exposures to the toxic metals lead and methylmercury. Dr. Manautou completed his undergraduate training in pharmacy at the University of Puerto Rico in 1985 Jose E. and went on to carry out graduate Manautou work at Purdue University. His Ph.D. research under the direction of Dr. Gary Carlson focused on the capacity of the lung to metabolize ethanol via oxidative, non-oxidative (esterification with free fatty acids) and conjugative pathways, such as glucuronidation and sulfation. After completing his graduate studies, he accepted a post-doctoral position in biochemical toxicology at the University of Connecticut in the laboratory of Dr. Steven Cohen; he then joined the faculty at the University of Connecticut in the Department of Pharmaceutical Sciences. For the past 10 years as an independent academic scientist, Dr. Manautou’s research efforts built on early findings from his post-doctoral work on acetaminophen. His research interests focus on the study of mechanisms underlying the hepatoprotective actions conferred by a class of compounds known as peroxisome proliferators. He has published a number of seminal articles focused on pathways involved in cytoprotection and is currently evaluating transcriptional regulation of hepatic transport proteins during liver injury. up-to-date information at www.toxicology.org AWARDS Dr. Manautou’s dedication to the training of young scientists is unmatched. His students speak proudly of his continued mentorship through daily problem solving, while allowing them the autonomy and flexibility needed for them to guide the path of their research projects. In addition to managing his research laboratory, Dr. Manautou participates on a number of committees including the National Research Council Committee on Human Health Risks of Trichloroethylene and the European Commission Sixth Framework Programme on Food Quality and Safety on Risk Assessment of Non-Dioxin-Like Polychlorinated Biphenyls. Also worth mentioning is Dr. Manautou’s strong commitment to the Society of Toxicology. Dr. Manautou has been active on the Placement Committee, Mechanisms Specialty Section, and Minority Program where he has held a number of appointments. Most recently, Dr. Manautou served as SOT Councilor and was active as the Council Liaison to the Specialty Sections, Education Subcommittee for Minority Programs, the NIH Funding Task Force, and the Special Interest Group Task Force. 37 45th Annual Meeting and ToxExpo 2006 Award Winners (Continued) 45th Annual Meeting & ToxExpo potential partners in industry and government.

Courses can be applied toward certifying and licensing board requirements and may also be used for recertification with the American Board of Toxicology (ABT). Both basic and advanced course topics are offered. The basic course is intended to provide a broad overview of an area or to assist individuals in learning new techniques or approaches. The advanced course is intended to be of interest to individuals with previous knowledge of the subject or already working in the field. AM 02 (REPEATS AS PM 08) Endorsed by: Comparative and Veterinary SS Regulatory and Safety Evaluation SS* Over the past decade, a range of targeted anti-cancer drugs have been developed that are designed to interfere with one or more of the many molecular mechanisms that drive tumor growth. The molecularly-targeted approach to the development of these new anti-cancer drugs has created a false impression that these newer drugs, unlike earlier cytotoxic anti-cancer drugs, will be non-toxic. Cytotoxic drugs are typically administered in short courses of maximal doses (MTD). This is not necessarily appropriate for targeted therapies, which can require long-term therapy and for which it is often difficult to determine the biologically most effective dosage (BED). This course will focus on different aspects of regulatory, pre-clicical, and clinical targeted anti-cancer drug development. The first speaker will focus on tumor cell biology and the respective cell signaling pathways that hold promise for targeted anti-cancer therapy. The second speaker will present differences in pre-clinical development philosophy between cytotoxic and targeted anti-cancer drugs. The third speaker will discuss specific examples of pre-clinical development of targeted biotherapeutics. The fourth speaker will discuss biomarkers as endpoints of clinical efficacy and safety assessment. The final speaker will focus on regulatory considerations of pre-clinical development of targeted therapies, highlighting differences between cytotoxic and targeted therapies. This advanced course in drug development is targeted to government, biotechnology and pharmaceutical toxicologists as well as general toxicologists with an interest in cancer chemotherapy. *The Primary Specialty Section (SS) or Regional Chapter (RC) Endorser USE OF GENOME DATABASES FOR TOXICOLOGY BASIC Chairperson(s): William B. Mattes, Gene Logic Inc., Gaithersburg, MD. Endorsed by: Mechanisms SS National Capital Area RC Molecular and genomic information is increasingly an important part of all biological research including toxicology. While toxicologists often focus on data from microarray-based expression profiles, other molecular data, including the organization and function of genes in the context of the cell, the physical genome and sequence, and the relationships between species in terms of this organization, can provide important insights. Therefore facilities with public molecular biology databases and search tools are essential to all toxicologists. Moreover, the recent availability of complete genomes, including the human, mouse and rat, has made genome-wide queries and comparative genomics readily accessible to all researchers and has the potential to revolutionize medical research and practice. The largest public repository of biological sequence information is maintained by the National Center for Biotechnology Information (NCBI) at the National Library of Medicine. This course will describe the molecular database resources, including sequences, structures and genomes, and the tools available through the WWW interface to the NCBI. The discussion will then focus on using these tools and databases as well as the specialized genomic resources. The Entrez and BLAST Web services will be demonstrated and how both can be used as a biological discovery system in toxicology will be illustrated. This tutorial is intended as an overview and introduction of NCBI genomic and molecular databases to toxicologists, but even experienced users will find it helpful. • Use of Genome Databases for Toxicology, Peter S.

Endorsed by: Regulatory and Safety Evaluation SS Reproductive and Developmental Toxicology SS* Risk Assessment SS Endorsed by: Inhalation SS* Molecular Biology SS Toxicologic & Exploratory Pathology SS This course is intended to provide a general overview for scientists responsible for the design, conduct and monitoring of reproductive toxicity studies. The course will focus on reproductive biology, study design considerations, reproductive endpoints, data interpretation and use of data in risk assessment. Reproductive toxicity studies are among the most complex and challenging studies in the field of toxicology. The studies assess multiple interrelated endpoints of male and female reproductive function. In order to properly design, conduct and interpret these studies, a fundamental knowledge of male and female reproductive system development, anatomy, physiology, and endocrinology are required. This course will discuss the designs of reproductive studies for regulatory submission. Individual lectures will discuss the anatomy and physiology of the male and female reproductive systems as well as endocrine regulation of these systems. Evaluation of toxicity endpoints to assess male and female reproductive function will also be discussed including mating, fertility, estrous cyclicity, spermatogenesis, sexual behavior, parturition, reproductive hormone analysis, nesting and nursing behavior, reproductive organ weights and histopathology, and proper use of statistical analysis. The course will conclude with discussions on some common issues related to reproductive toxicity testing, interpretation of results, and how these results are ultimately used to assess potential risks to human reproduction. In summary, this course will present the key information required for the design of reproductive toxicity studies and interpretation of reproductive toxicity data and provide guidance for use of the data for risk assessment of human reproduction. • Advances in the disciplines of cell and molecular biology have led to the development of novel biotechnologies capable of generating “global molecular profiles” for in situ toxicological assessment. These technologies should accelerate our understanding of molecular basis for potential toxicity and susceptibility. This course will provide both theoretical and practical information on these emerging high throughput technologies, their applicability, interpretation and integration to gain a more comprehensive understanding of cellular responses to chemical/toxicant stress. The first presentation will cover the potential utility of Laser Capture Micro-Dissection in isolating specific cell populations for toxicological assessment at the level of RNA and proteins. The second presentation will provide the ongoing evolution of gene expression profiling approaches from “toxicogenomics” to systems biology. The third presentation will provide an overview of proteomic technologies in analyzing the protein interactions and downstream signaling mediators involved in toxic response pathways. The final presentation will examine the capabilities of high throughput technologies in identifying the single nucleotide polymorphisms (SNPs) and their predictive value for characterizing underlying genetic susceptibilities to toxicants. Overall the course is aimed at educating toxicologists on the array of new technologies available to research toxic outcomes and their underlying mechanisms. The goal is to move towards a better and reliable prediction and extrapolation of toxic responses. This course will also serve as a refresher course for scientists, technical and regulatory staff involved in various stages of compound development or regulation.

Endorsed by: Comparative and Veterinary SS* Reproductive and Developmental Toxicology SS Toxicologic & Exploratory Pathology SS Endorsed by: Mechanisms SS Metals SS* Neurotoxicology SS Risk Assessment SS Hormones secreted by cells of the endocrine system have diverse effects throughout the body. Exposure to xenobiotic compounds can result in profound changes to the endocrine organs and/or their target cells. Significant species differences exist in the structure and function of endocrine and reproductive organs making interpretation of test results and extrapolation from animal models to humans more challenging. In addition to the numerous anatomical and physiological differences, there are also species variations in metabolism and response to toxicants. It is the goal of these presentations to give an overview of the structure, function, regulation, and toxic responses of selected endocrine and reproductive organs. In addition, the speakers will discuss the hormonal assays and other mechanistic approaches necessary to make species comparisons, and to extrapolate the findings from animals to humans. Each presentation will briefly describe important species differences with regard to anatomy, endocrine physiology, and response to different classes of xenobiotic chemicals by selected endocrine and reproductive organs such as the thyroid (follicular cells), ovary, and testis (Leydig cells). One presentation will focus on the principles and pitfalls of hormonal measurements in laboratory animals considering advantages/disadvantages of different methods, species specificity of certain assays, most appropriate sampling times, and other useful items to consider in future protocol development. Following completion of this workshop, attendees should have a more complete understanding of the comparative endocrinology and toxicology of selected endocrine and reproductive organs in laboratory animals. • Comparative Endocrine Toxicology of the Thyroid Gland, Charles C.

Nett, Colorado State University, Fort Collins, CO. up-to-date information at www.toxicology.org Metals are ubiquitously present in environment, essential to human health, and yet toxic upon overexposure. They are neither synthesized by living matter nor destroyed by human endeavour. Metals play a significant role in many human diseases. Unique physical, chemical and biological properties allow metals to persist in the body, cause long-lasting effects, and yet leave few choices for therapeutic intervention. A fundamental question remains, namely what makes metals toxic in promoting carcinogenesis, neurotoxicity, reproductive, liver and kidney injuries, or generalized metabolic disease? This basic course is intended to address the essentials in metal toxicology by providing cutting-edge knowledge on the concepts, theories, clinical outcome, and research methodologies in metal toxicology. The first lecture will highlight the clinical symptoms of metal-induced human diseases, common routes of exposure, and therapeutic intervention. Two subsequent lectures will address metal pharmacokinetics and the general mechanisms of metal-induced cell death, specifically apoptosis. The final lecture will discuss animal models, based on either symptomatic outcomes or biochemical consequences, for studying metal toxicities. Speakers will address these essentials by providing details specific to “hot” metals, such as arsenic, mercury, manganese, lead, and uranium. The course will serve as an introduction to those who desire an expanded knowledge on essentials of metals in human health and diseases, essentials of toxicological actions of metals, and essentials of research approaches in metal toxicological investigation. The course will also be of interest to others engaged in wider aspects of carcinogenesis, neurotoxicology, risk assessment, and occupational health. 51 • Metals in Human Diseases: Symptoms and Clinical Intervention, Wei Zheng, Purdue University, West Lafayette, IN. • Distribution of Metals: Role of Metal Transporters and Selectivity of Disposition, Michael Aschner, Vanderbilt University, Nashville, TN. • Molecular Mechanism of Metal Toxicity: Signal Transduction and Oxidative Stress, Anumantha Kanthasamy, Iowa State University, Ames, IA. • Animal Models Used in Metal Toxicological Research, Janelle Crossgrove, Purdue University, West Lafayette, IN. 45th Annual Meeting and ToxExpo 45th Annual Meeting & ToxExpo CE Continuing Education (Continued) PRACTICAL STRATEGIES FOR EVALUATION OF IMMUNOSUPPRESSION IN PHARMACEUTICAL DEVELOPMENT AM 07 TARGETED THERAPEUTIC APPROACH TO ANTI-CANCER DRUG DEVELOPMENT PM 08 (REPEAT OF AM 02) BASIC Chairperson(s): Vijayapal Reddy, Eli Lilly & Company, Greenfield, IN and Myrtle A.

This advanced course in drug development is targeted to government, biotechnology and pharmaceutical toxicologists as well as general toxicologists with an interest in cancer chemotherapy. Increased focus has been placed on evaluating immunotoxicity, particularly immunosuppression, in pharmaceutical development of small molecules and biologics following recent issuance of regulatory guidelines from FDA and CPMP and current ICH discussions on harmonization. Toxicologists, pathologists, immunologists and clinicians in the drug industry are faced with the challenge of addressing the intent of the current guidance documents in a scientifically valid and responsible manner. An integrated approach is necessary to provide a weight of evidence for signal detection in routine toxicity studies as well as conducting immunotoxicity studies or adding endpoints in routine toxicity studies to assess immunophenotyping or functional immune alterations. The toxicologist is also central in communicating the risk to clinicians and regulators following interpretation of non-clinical immunotoxicology data and participating in the search for clinical immune biomarkers to ensure clinical safety of trial participants. The goal of this course is to discuss regulatory guidance and use case examples to illustrate the integration of toxicology, pathology and immunology in addressing both recent scientific advances and practical approaches in the pharmaceutical company setting and how this knowledge impacted clinical trials and labeling, with a focus on drug-induced immunosuppression. Similarities and differences in FDA and CPMP immunotoxicity guidance documents and recent progress in ICH harmonization will be discussed. Signal detection, including data from standard toxicity studies and the controversies among toxicologists and pathologists in following the guidelines will be addressed, including the recently drafted Best Practice Guideline for the Routine Pathology of the Immune System by the STP Immunotoxicology Working Group. Immunophenotyping conducted by flow cytometry or lymphoid immunohistochemistry will cover recent advances with case studies. Functional assays, such as T-cell dependent antibody response, natural killer cell activity, host resistance macrophage/neutrophil function, and cell-mediated immunity will be discussed with regard to design and timing in drug development from an immunotoxicologists perspective. Finally, interpretation of non-clinical immunotoxicology data for risk assessment in clinical trials and use of clinical immune biomarkers will be featured. • Immunotoxicology: What’s New on the ICH Harmonization Front?

Stump, WIL Research Laboratories, LLC, Ashland, OH. ADVANCED Chairperson(s): Richard S. Pollenz, University of South Florida, Tampa, FL. Endorsed by: Regulatory and Safety Evaluation SS Reproductive and Developmental Toxicology SS* Risk Assessment SS Endorsed by: Mechanisms SS* The mechanistic analysis of cellular responses to xenobiotics requires the functional characterization of changes in both gene and protein expression. The ability to study changes to both genes and proteins in vitro and in vivo has become accessible to more laboratories with the development of molecular tools such as microarrays, siRNA, recombinant protein expression, and viral gene delivery. However, the ability to utilize these techniques and generate reproducible results requires a detailed understanding of each procedure. Thus, the goal of this course is to provide the investigator with an overview of experimental design and the use of proper controls for four cutting-edge techniques. The first talk will focus on experimental design and analysis of gene expression studies utilizing microarrays. The second presentation will discuss recent advances in the chomatin-immunoprecipitation (ChIP) assay for the analysis of protein interactions at the level of DNA. The third presentation will discuss gene delivery into hepatocytes in vivo utilizing the adenovirus system. Finally, the last presentation will discuss the advantages and disadvantages of recombinant protein expression in cultured cells with emphasis on the level and functionality of the expressed protein and the use of siRNA. The course will be of broad interest to those laboratories considering contemporary mechanistic approaches to gene and protein expression as well as those currently investigating these endpoints. This course is intended to provide a general overview for scientists responsible for the design, conduct, and monitoring of reproductive toxicity studies. The course will focus on reproductive biology, study design considerations, reproductive endpoints, data interpretation, and use of data in risk assessment. Reproductive toxicity studies are among the most complex and challenging studies in the field of toxicology. The studies assess multiple interrelated endpoints of male and female reproductive function. In order to properly design, conduct and interpret these studies, a fundamental knowledge of male and female reproductive system development, anatomy, physiology, and endocrinology are required. This course will discuss the designs of reproductive studies for regulatory submission. Individual lectures will discuss the anatomy and physiology of the male and female reproductive systems as well as endocrine regulation of these systems. Evaluation of toxicity endpoints to assess male and female reproductive function will also be discussed including mating, fertility, estrous cyclicity, spermatogenesis, sexual behavior, parturition, reproductive hormone analysis, nesting and nursing behavior, reproductive organ weights and histopathology, and proper use of statistical analysis. The course will conclude with discussions on some common issues related to reproductive toxicity testing, interpretation of results, and how these results are ultimately used to assess potential risks to human reproduction. In summary, this course will present the key information required for the design of reproductive toxicity studies and interpretation of reproductive toxicity data and provide guidance for use of the data for risk assessment of human reproduction. • Design and Analysis of Microarray Experiments, Thomas Sutter, Feinston Center for Genomic Research, University of Memphis, Memphis, TN. • • Reproductive Toxicity Testing: Study Designs and General Considerations, Barry S.

Dorman, CIIT Centers for Health Research, Research Triangle Park, NC. Endorsed by: Drug Discovery Toxicology SS* Endorsed by: Comparative and Veterinary SS Neurotoxicology SS Toxicologic & Exploratory Pathology SS* Toxicologists have traditionally considered that chemicals are absorbed and distributed throughout the body largely due to their lipid solubility and diffusivity through cell membranes. We also consider drug metabolism as a process that makes chemicals more water soluble so they will less readily pass cell membranes and be more rapidly excreted. However, it was not understood how the water-soluble metabolite could exit the cell to be excreted. During the last decade a number of transporters have been identified that not only are responsible for the excretion of chemicals, but also for the absorption and distribution of xenobiotics. This course, highlighting the progress made in this research field as both timely and of significant interest to a large number of SOT members who are in academic, government and industrial sectors. This course will give an overview of the families of transporters involved in absorption, distribution and excretion of drugs and chemicals, as well as presentations specific to the major tissues where transporters are known to influence toxicity. The roles of transporters in disposition and toxicity in the liver, kidney, intestine, and brain will be discussed. • Overview of the Families of Transporter Responsible for the Absorption, Distribution, and Excretion of Drugs, Curtis D.

The course will start off with a review of the normal anatomy and histology of the adult nervous system. This overview will also discuss the ways in which neuropathology and functional assays of motor activity and other behaviors relate to one another. The second lecture relates to tissue handling techniques and basic approaches in neuropathology. This topic is critically important since the ability to detect chemical-induced neuropathology requires proper tissue fixation and processing. Although the second lecture will largely focus on rodent tissues, the approaches and methods to be discussed can be easily adapted to other species. The course will then transition into two presentations focused on common lesions induced by model neurotoxicants. One presentation will focus on central nervous system effects while the latter lecture will address peripheral neuropathies. Our final presentation will discuss morphometric approaches in neuropathology including a discussion of the use of magnetic resonance imaging methods in neurotoxicologic pathology. Participants in this course will gain a greatly improved appreciation of basic neuropathology and applications to toxicology. 54 SOT's 45th Annual Meeting 45th Annual Meeting and ToxExpo Continuing Education (Continued) ASSESSING AIRWAY INJURY AND REMODELING INDUCED BY INHALED POLLUTANTS USING MAGNETIC RESONANCE IMAGING, MICROSCOPY, AND MODELING PM 13 BASIC Chairperson(s): Jack R. Harkema, Michigan State University, East Lansing, MI and Richard Corley, Pacific Northwest National Laboratories, Richland, WA. Endorsed by: Inhalation SS* The goal of this course is to present state-of-the-art methods of assessing injury and remodeling of the conducting airways caused by acute or chronic exposures to airborne toxicants including environmental pollutants (e.g., particulate matter, ozone, cigarette smoke, fungal, and bacterial toxins). The nature, severity, and distribution of airway lesions caused by these inhaled toxicants are due to an integration of several factors including the physicochemical characteristics of the inhaled toxicant (e.g., size of the particles, reactivity of the gas), the exposure regimen (e.g., short-versus long-term, continuous versus episodic), local intra-airway dosimetry (e.g., hot spots of deposition at airway bifurcations, slow clearance from sites of overload), and cellular susceptibility (e.g., sensitive versus resistant epithelial cell types). Toxicant-induced alterations to the airway structure range from oncotic or apoptotic cell death of epithelial cells lining the luminal surface with concurrent acute inflammation to marked remodeling of the airway wall due to intramural fibrosis, epithelial hyperplasia/metaplasia, and chronic active inflammation. The strengths and limitations of a variety of state-of-the-art imaging techniques for visualizing macroscopic changes to the respiratory tract, including magnetic resonance imaging and computed tomography, will be presented along with those of more routine methods of light, electron, and confocal microscopy for assessing tissue and cellular pathology caused by inhaled pollutants. The fundamental principles of airway stereology will also be presented and how these mathematically proven morphometric techniques may be used to quantify, without bias, changes to these tubular structures in order to estimate severity of complex lesions. Finally, presenters will describe the development and implementation of computational models of geometrically correct upper and lower airways used to define, site-specific, dose-response relationships along the respiratory tract of laboratory animals and to estimate the risk of air pollutant exposures to human health. • An Overview of Airway Injury and Remodeling Caused by Inhaled Toxicants: From the Nose-to-the-Lung and from Gases to Particles, Jack R.

Friday HESI/SETAC IN VITRO ADME BIOACCUMULATION WORKSHOP Details for this workshop can be found under the Friday, March 3 listing of this event. HESI/SETAC IN VITRO ADME BIOACCUMULATION WORKSHOP Saturday, March 4 2:00 PM to 5:00 PM Room 14B The ILSI Health and Environmental Sciences Institute’s (HESI) Development of Methods for a Tiered Approach to Assess Bioaccumulation of Chemicals Subcommittee and the Society of Environmental Toxicology and Chemistry (SETAC) are jointly hosting a workshop March 3–4, 2006 to explore the range of in vitro techniques that may be applied to evaluate the bioaccumulation potential of chemicals. COMMITTEE CHAIR ORIENTATION If you will be a Committee Chairperson in 2006–2007, please make plans to attend the Committee Chairperson Meeting scheduled for 2:00 PM– 5:00 PM, Saturday, March, 4. With new committee assignments taking effect on May 1, 2006, the meeting is intended to provide new (and current, if desired) chairpersons with a basic tutorial on the SOT structure, operation, and strategic direction. For additional information, please contact SOT Headquarters. HESI is a global branch of the International Life Sciences Institute, a public, non-profit scientific foundation with branches throughout the world. HESI provides an international forum to advance the understanding and application of scientific issues related to human health, toxicology, risk assessment and the environment. HESI is widely recognized among scientists from government, industry and academia as an objective, sciencebased organization within which important issues of mutual concern can be discussed and resolved in the interest of improving public health. Saturday, March 4 5:30 PM to 9:00 PM Room 16A The need for this workshop has come about as a result of growing concerns regarding the persistence, bioaccumulation, and toxicity of substances (PBTs) released into the environment. New laws resulting from enactment of the United Nations Stockholm Convention (Persistent Organic Pollutants (POPs) Protocol) in May 2004 have led to significant new activity in the assessment of PBTs. To address the scientific challenges associated with developing bioaccumulation assessments for the many chemicals that need to be assessed in the coming years, there is a need to develop efficient, scientifically-defensible alternatives to existing methods. Domestic and international reporting requirements are facilitating the development of collaborative arrangements among industry, government, and academic scientists to identify additional methods for assessing thousands of chemicals.

PLENARY LECTURE: RISK COMMUNICATION—THE PERCEPTION GAP, AN UNRECOGNIZED ASPECT OF RISK Lecturer: David Ropeik, Harvard School of Public Health, Harvard University, Boston, MA. This talk will propose that the classic definition of Risk = Hazard x Exposure is incomplete. A definition that more fully reflects all aspects of risk is Hazard x Exposure x Perception. While it is often said that people are wrong or irrational when their fears don’t match the facts, their fears are real, and those fears often lead to behaviors that compound the risk to themselves and to society. The scientific understanding of the roots of risk perception will be explained. More effective risk communication, based on a respect for the realities of risk perception, will be offered as a vital tool for closing ‘The Perception Gap’ and encouraging people to make more informed and healthier choices.

Endorsed by: Molecular Biology SS Regulatory and Safety Evaluation SS Chairperson(s): Melissa Runge-Morris, Wayne State University, Detroit, MI. MONDAY Lipidomics, the study of the effect of lipids on cellular physiology and death, is a new and rapidly emerging area of research with great promise in molecular toxicology. Phospholipids make up cell and organelle membranes and by their physical-chemical properties are integral to the maintenance of cell homeostasis. In addition, these molecules are critical to cell signaling pathways. Therefore, to toxicologists this often-overlooked cell component plays interesting, and often pivotal, roles in toxicity and pathogenesis. For example, studies on the roles of phospholipids during phospholipidosis, apoptosis, phagocytosis, oxidative stress and mitochondrial dysfunction all can yield new and vital information about the mechanisms of such processes. In addition, a variety of advanced techniques for the assessment of phospholipids have increased our ability to perform lipidomics, including flow cytometry, electrospray ionization-mass spectrometry and high performance thin layer chromatography. Thus, lipidomics offers great promise into identifying mechanisms of toxicant-induced cell death. #12 9:30 LIPIDOMICS OF CELL DEATH. B. S. Cummings1, D. K. Monteith2, V. E. Kagan3 and B.

Endorsed by: Molecular Biology SS* The tight regulation of phase II xenobiotic-metabolizing enzymes such as the sulfotransferase (SULT), UDP-glucuronosyl transferase (UGT), Nacetyltransferases (NAT) and glutathione-S-transferases (GST) multigene families, represents an essential component of detoxication. In human populations, genetic polymorphisms determine the phenotype of NAT1 and NAT2 and together with tissue-specific gene expression, influence cancer risk following exposure to aromatic and heterocyclic amines in the environment. Emerging insights in the nuclear receptor field have demonstrated that the hepatic SULT and UGT enzymes are not only coordinately regulated by members of the nuclear receptor superfamily, but also modulate the levels of bio-active species that participate in nuclear receptor signaling. Superimposed on these advances, the activation of the Keap1/ Nrf2 signaling pathway by oxidative stress mediators in the environment has been recently shown to control the expression of key members of the GST multigene family, as well as other xenobiotic-metabolizing enzyme target genes. This symposium will provide an updated analysis on the genomic and transcription factor controls that regulate SULT, UGT, NAT and GST enzymes. Focused emphasis will be placed on the implications of altered phase II enzyme gene expression for toxicity in humans. #17 9:30 REGULATION OF PHASE II XENOBIOTIC METABOLIZING ENZYMES: IMPLICATIONS FOR HEALTH AND DISEASE.

Chairperson(s): David C. Dorman, CIIT Centers for Health Research, Research Triangle Park, NC and Jack R. Harkema, Michigan State University, East Lansing, MI. Endorsed by: Dermal Toxicology SS* In Vitro SS Endorsed by: Inhalation SS Metals SS Neurotoxicology SS Toxicologic and Exploratory Pathology SS* Nanoscale materials (whether engineered or anthropogenic) are structures with characteristic dimensions between 1 and 100nm and are present at ever increasing concentrations in the environment. Engineered nanomaterials include the prototype C60 molecules, otherwise known as fullerenes or “Bucky balls”, nanowires, nanofibers, nanoscissors, and nanotubes. The manufacture of these nanomaterials is scaling up to commercial levels. Their smaller size attributes additional physical properties, like conductivity and reactivity, which allows them to be used in telecommunications, alternative energy sources, and medical applications. These engineered materials vary in their structures and physicochemical compositions. Currently, efforts are being made to standardize the manufacturing practices, analytical and detection methods and nomenclature. However, little is known about their toxicity and recent reports are conflicting. Dermal, inhalation and oral exposure are all major probable routes of exposure. Since the skin is the largest organ of the body, it may be the utmost concern in terms of human health. The presentations in this symposium will address the background of these nanomaterials and will focus on new screening methodologies for assessing their cytotoxicity utilizing several types of skin model systems. Methodologies will include assays for skin viability, absorption, transport and gene expression and protein expression profiling. These presentations will provide a base line for interpretation of the toxicological implications for occupational or potential environmental exposure that could possibly be used in risk assessment. The olfactory system is unique in that it forms a direct interface between the air and the central nervous system (CNS). There is growing evidence that metals and other xenobiotics deposited within the nose can be absorbed at this site and then undergo transport along either the olfactory or trigeminal nerve, thus bypassing the blood-brain-barrier. One metal of special concern to be discussed in this symposium is manganese, a neurotoxic metal shown to be able to cross synapses in the olfactory bulb and migrate via secondary olfactory neurons to more distant nuclei of the brain. In some cases, direct olfactory transport is a major pathway by which an inhaled metal reaches the CNS. This symposium will present new discoveries concerning direct nose-to-brain transport of metals in the olfactory pathway. This symposium will also discuss likely mechanisms by which transport occurs and inter-species differences in nasal anatomy that may play a role in metal olfactory uptake and transport. #23 9:30 9:50 RISK ASSESSMENT IMPLICATIONS OF DIRECT NOSE-TO-BRAIN TRANSPORT OF INHALED XENOBIOTICS.

WORKSHOP SESSION: TOWARDS THE VIRTUAL HUMAN: ADDING MORE PHYSIOLOGICAL DETAIL TO BIOLOGICALLYBASED MODELS Chairperson(s): Robert DeWoskin, U.S. EPA, Research Triangle Park, NC and Torka Poet, Pacific Northwest National Laboratory, Richland, WA. MONDAY Endorsed by: Biological Modeling SS* Mechanisms SS Risk Assessment SS Monday, March 6 9:30 AM to 12:00 NOON Room 15A Biologically based models have proven applications in risk assessment, drug development, and health care primarily based upon their ability to predict outcomes and extend the usefulness of limited data sets. Biological models also help integrate diverse sets of data from in vitro and in vivo studies (and the many “omics” technologies) into a coherent theoretical framework of a chemical’s mode of action. The most common biological models currently used in risk assessments are physiologically based pharmacokinetic (PBPK) models, which simulate the pharmacokinetics of a toxin, generally at the whole body and organ level. A natural outcome of the increased use of biological models in risk assessment is an interest in ever increasing levels of physiological detail, with the ultimate goal being a highly predictive whole body or virtual human model. Progress has been slow; however, in part because of a lack of interaction between the physiology modeling community with its focus on medical applications and the PBPK modeling community with its focus on risk assessment. This workshop begins to bridge some of this gap by presenting an overview of the state of physiology modeling, some examples of systems level physiology models, a case study of a hybrid physiology/PBPK model with improved predictive capability, and a discussion of the challenges to using existing physiology models in risk assessment.

Endorsed by: Carcinogenesis SS Mechanisms SS Toxicologic and Exploratory Pathology SS* Toxicogenomics has recently emerged as an extremely promising subdiscipline of environmental health sciences. It has received an enormous amount of attention at a large number of international toxicology meetings as a powerful, new tool for toxicologists that may considerably accelerate discovery of the mechanisms of environment-associated diseases, reveal novel biomarkers or surrogate biomarkers of both exposure and effect, improve scientists’ ability to characterize hazard, and serve as a foundation for advancing risk assessment. Careful assessment of linkages between the omics data and conventional parameters of toxicity is very important for both validation and evaluation of toxicogenomics data. Phenotypic anchoring of gene expression data to toxicological and pathological indices removes the subjectivity of novel molecular analyses and is important to distinguish the toxicological effect from changes that may be unrelated to toxicity. Importantly, several recent studies demonstrated the utility of this approach and showed how a careful examination of different types of the data available to the toxicologists today helps to understand organ-specific toxic events, identify conserved responses across species, and bring other disciplines, such as genetics, into the toxicology research. Collectively, the linkage of toxicogenomic data to specific sites within tissues and specific cellular populations in affected tissues should result in better selection of appropriate animal models, reduction in the number of animals used, and enhanced insight into pathways of toxicity and disease processes that have been heretofore unattainable, ultimately enhancing risk assessment. #311 1:30 ADVANCING TOXICOLOGY BY IMPROVING LINKAGE OF TRADITIONAL TOXICITY AND PATHOLOGY ENDPOINTS WITH TOXICOGENOMICS.

The laboratory rodent was first introduced by E.V. McCollum for nutritional studies the early part of the last century. For some 50 years, the animal was not standardized, and was the largest variable in any animal based research A significant advance was the standardization of the laboratory rodent by Henry Foster and the formation of Charles River Laboratories to provide animals that are the same from order to order. By standardizing the laboratory rodent, it became possible for laboratories in Europe, the United States, and Japan to actually be able to reproduce studies and know that the potentially largest variable, the animal, was now controlled. The advances made with animals has significantly improved the health of both animals and humans populations, resulting in an expanded life span and an enhanced quality of life. As science advanced and more specific questions could be asked- experiments to understand mechanisms and mode of action and studies aimed at subcellular and molecular components of cells- it became necessary to learn to culture cells (both human and animal) to further understand biology and the effects of drugs and chemicals on their function. Today, many new and exciting approaches are available for the scientist - from using monolayers of cells to three-dimensional reconstituted tissues, to multiple cell types allowing the understanding of the interaction between complex systems. These newer systems and different biological matrixes offer the opportunity to advance science and our understanding of the underlying biology by yet another step. This symposium presents some of these systems and focuses on their use in toxicological studies. #317 1:30 THE BIOLOGICAL MATRIX OF IN VITRO SYSTEMS AND THEIR USE IN TOXICOLOGY. A. Goldberg1 and S.

Endorsed by: Immunotoxicology SS Neurotoxicology SS Women in Toxicology SS There is overwhelming evidence that cytokines, neuropeptides, neurotransmitters, and hormones, as well as their receptors, are an integral and inter-regulated part of the central nervous system, the endocrine system, and the immune system. Immune cells synthesize and secrete peptide hormones and neurotransmitters, which can have autocrine (immune system) and paracrine (endocrine and nervous systems) effects. Additionally, nerve terminals containing neurotransmitters have been found in lymphoid tissues in close association with lymphoid cells, and the neurotransmitter is released when an antigen insult is present. Also, receptors for neuropeptides, neurotransmitters, and hormones are present on lymphoid cells. These findings make it reasonable to suspect that some chemicals may exert their immunomodulatory effects indirectly on the immune system, by acting to modulate the activity of the nervous or endocrine systems. It is now critical that we begin to address the probable role played by neuroendocrine-immune interactions in a chemical-induced immune toxicity that may involve multiple organ systems. The goal of this symposium is to describe advances in our understanding of the role of the neuroendocrine-immune axis in chemical toxicity and human health. #323 1:30 INDIRECT MECHANISMS OF TOXICITY: ADVANCING OUR UNDERSTANDING OF NEUROENDOCRINE – IMMUNE INTERACTIONS.

Endorsed by: Carcinogenesis SS* Mechanisms SS Regulatory and Safety Evaluation SS Toxicologic and Exploratory Pathology SS Hemangiosarcoma is an aggressive, malignant tumor of endothelial cells that is rare in humans. In the 12 regions of the US National Cancer Institutes Surveillance, Epidemiology, and End Results (SEER) database, the incidence rate of hemangiosarcoma between 1996 and 2000 was 0.21 new cases per 100,000 people (0.00021%). Hemangiosarcoma in humans commonly occurs on head and neck and is associated with skin structures. Liver hemangiosarcoma is associated with exposure to genotoxic compounds such as Thorotrast or vinyl chloride. In contrast, hemangiosarcoma occurs spontaneously in liver, spleen, bone marrow, lymph nodes and skin at a high incidence in rodents. The background incidence in B6C3F1 mice reported from the National Toxicology Program database is 5.4% in males and 2.7% in females with a range from 0% to 12%. The incidence in Wistar rats ranges from 0 to 3.4 %. These data suggest that mice are more susceptible to development of spontaneous hemangiosarcoma than rats and much more susceptible than humans. Hemangiosarcoma in rodents, primarily mice, has been reported in the labeling of a number of marketed drug products and in the literature with several chemicals. Some of these compounds demonstrated genotoxic potential in nonclinical testing and thus a plausible mechanism for tumor induction involving DNA adduct formation. Others, however, are clearly nongenotoxic and a mode of action is more difficult to establish. Regardless, findings of hemangiosarcoma have significant impact on decisions made regarding further development of these agents and future usage. Recent research has provided a great deal of information on epigenetic processes of tumorigenesis involving oxidative stress, altered gene expression and species differences related to endothelial homeostasis that provide a basis for risk assessment. #328 1:30 MODE OF ACTION ASSOCIATED WITH INDUCTION OF ENDOTHELIAL CELL TUMORS - HEMANGIOSARCOMA.

Endorsed by: Metals SS Neurotoxicology SS* Risk Assessment SS MONDAY Lead is a xenobiotic metal with no historically known function in cellular growth, proliferation, or signaling. Decades of research characterizing the toxicology of lead have shown it to be a potent neurotoxicant, especially during nervous system development. New concepts in the neurotoxicology of lead include advances in understanding the mechanisms and cellular specificity of lead. Environmental factors such as stress and socioeconomic status have been shown to potentiate the effects of lead through elevated glucocorticoid levels acting on the mesocorticolimbic system. New structural MRI studies have shown relationships of lead to alterations in CNS volumes and to the prevalence and severity of white matter lesions. Cellular models of learning and memory have been utilized to investigate the potential mechanisms of Pb-induced cognitive deficits. Examination of long-term potentiation in the rodent hippocampus has revealed Pb-induced increases in threshold, decreases in magnitude, and shorter retention times of synaptic plasticity. Structural plasticity in the form of adult neurogenesis in hippocampus is also impacted by Pb exposure. The action of lead on glutamate release, NMDA receptor function, or growth factor expression may underlie perturbations in synaptic plasticity and contribute to learning impairments. Evidence is also mounting that lead can accumulate in astroglial cells by utilizing the cellular transport systems normally used for essential minerals such as calcium. Additionally, glial cells may use glucose regulated protein (GRP78), a molecular chaperone in the endoplasmic reticulum, to temporarily bind lead during the lead accumulation process. However, this binding may contribute to increased susceptibility of the brain to stress, as GRP78 is also a stress protein and a chaperone for interleukine-6. Lead exposure in early life has been implicated in subsequent progression of Alzheimers Disease (AD) in rodents. This exposure caused upregulation of mRNA coding for beta-amyloid precursor protein, which is cleaved into beta-amyloid peptides associated causally with AD. This new body of research presents compelling evidence that even very low exposures of lead have adverse effects on the nervous system, that environmental and genetic factors increase nervous system susceptibility to lead, and that exposures in early life cause neurodegeration in later life. #335 1:30 NEW CONCEPTS IN THE NEUROTOXICOLOGY OF LEAD.

Endorsed by: Mechanisms SS* Tight regulation of cell death and survival is key for normal embryonic development and the maintenance of tissue turnover or homeostasis. Tissue homeostasis occurs when a balance is achieved between cell renewal and cell death so that no net change in cell number is present. Normal homeostatic cell deletion is controlled, at least in part, by apoptosis. Consequently, dysregulation of apoptotic cell death has been implicated in the onset of numerous pathologies, including liver and autoimmune disorders, cardiovascular disease, and cancer. Further, environmental factors that contribute to an increased risk of these diseases appear to do so, at least in part, by disrupting the balance between cell death and survival. Likewise, preventive and therapeutic measures to control these diseases are often designed to block aberrant cell death or survival. Whether a cell survives or dies in the presence of a toxic stimulus is often determined by proliferative status, repair enzyme capacity, and/or the ability to induce or activate proteins that either promote or inhibit apoptotic cell death. Although the underlying molecular and biochemical mechanisms, in some cases, are at least partially understood, in many other instances they remain unclear. This symposium will present important new insights into mechanisms regulating cell death or survival in response to toxic stimuli.

Endorsed by: Risk Assessment SS Occurrences of asbestos-related contamination, such as the vermiculite mine in Libby, Montana, and the World Trade Center, have highlighted the need to update the state of science with regard to asbestos toxicity and exposure assessment. The purpose of this workshop is not only to provide an overview for toxicologists, but also to highlight the advances in a number of important areas. Recent work by U.S. EPA in examining the carcinogenic and non-carcinogenic effects of asbestos will be presented. The technical issues of assessing asbestos hazard in an indoor environment are presented. New data from NIOSH will update the dose-response analysis of the mortality of textile workers. Research into cellular and molecular mechanisms of lung and pleural diseases is opening up new up-to-date information at www.toxicology.org 87 MONDAY hypotheses on the mechanisms of action of asbestos toxicity. In the area of asbestos exposure assessment, improvements in analytical and counting methodologies will be discussed. This presentation will also provide some preliminary results of a sensitivity analysis being conducted by EPA on a quantitative cancer model that divides asbestos fibers into four bins (diameter < .4um), as a function of mineral type (chrysotile versus amphiboles), and length (5-10um, > 10 um). EPA has been working to establish quantitative uncertainty bounds around the fitted model parameter estimates and performing sensitivity analyses to help characterize confidence in these values. The preliminary results for lung cancer indicate that confidence in the fitted parameters shows that the best results are obtained for the potency values for the long fibers, as compared to the potency values for shorter fibers. combination of perspectives, this session will appeal broadly to those who are interested in studies of the molecular and biochemical mechanisms of cell death and survival. 45th Annual Meeting and ToxExpo 45th Annual Meeting & ToxExpo Program Description (Continued) Monday, March 6 1:30 PM to 4:30 PM Room 7A #360 3:50 THE DIFFERENTIAL RECRUITMENT OF ERα TO CYP1A1 BY BNF, ICZ, AND DIM AND THE IMPORTANT ROLE OF ERα IN AHR TRANSCRIPTION.

Sponsor: M. Ema. The U.S. Environmental Protection Agency is currently reassessing existing and new science that underlies current PM and ozone regulation. The scientific literature from air quality to epidemiological studies suggest the existence of toxic entities in the ambient and potential adverse health effects associated with their exposure. Animal toxicology studies have yet to provide convincing dose-appropriate evidence to support the adverse human health effects reported in epidemiological studies. The lack of molecular mechanisms indicating the biological plausibility for health effects and uncertainties associated with epidemiological investigations necessitate the need for developing an integrated research strategy by scientists from various disciplines in a larger more comprehensive forum to define health outcomes and risks. The present symposium is a ‘think outside the box’ forum to facilitate innovative global perspectives on air pollution from bench to public health outcomes inclusive of risk assessment and regulation. The panel will discuss current research efforts in understanding the complexities of ‘One atmosphere’ approaches to air pollution and the impacts on public health and the scientific basis of regulation. The issues discussed will include (1) the state of the art efforts for a comprehensive qualitative and quantitative analysis of the air sheds across U.S.; (2) determination of air quality based on sources of emission characteristics and reduction in source; (3) air quality and health effects assessments; (4) potential toxic constituents in the ambient as determined by animal toxicology studies and; (5) integrative analyses utilized in developing criteria for regulation of PM from the ‘one atmosphere’ approach. The objective is open and free discussion of current and alternative approaches to address public health concerns regarding air quality regulation effectively and efficiently. 112 SOT's 45th Annual Meeting 45th Annual Meeting and ToxExpo 45th Annual Meeting & ToxExpo #705 4:30 THE COMPLEXITIES OF AIR POLLUTION REGULATION: THE NEED FOR AN INTEGRATED RESEARCH AND REGULATORY PERSPECTIVE.

Endorsed by: Career Resource and Development Committee Education Committee* Women in Toxicology SS Distance learning has definitely come of age. On-line courses represent an impressive knowledge base which is now relatively easy to access by college students as well as individuals seeking mid-life career changes and/or advancement. Coupling electronic tools with teaching, asynchrony with synchrony, distance learning (asynchronous) courses can no longer be ignored as registration for them expands and types of offerings proliferate. This rapid rate of development has, in many respects, resulted from an increased awareness and appreciation of these techniques by many teachers and students. The common-sense practicality associated with these endeavors has dispelled much of the mysticism surrounding this area of education. Moreover, distance learning has come down-to-earth for many people around the globe offering them opportunities for higher education that, heretofore, would never have been obtainable. Both the thinking and the technological tools behind development of distance learning courses in toxicology will be presented. The speakers will be addressing on-line course content and delivery, nationally and internationally. Current on-line courses/programs will be discussed with respect to development, efficacy and quality. Asynchrony will be defined. up-to-date information at www.toxicology.org Endorsed by: Ethical, Legal, and Social Issues SS Risk Assessment SS Currently both Federal and State courts are attempting to adequately define criteria for establishing or dismissing causal relationships between toxicological effects and exposures to various agents such as drugs and chemicals. Although Federal and State courts in the Frye, Daubert and Havner rulings have stiffened the requirements for causation, it is the Bradford Hill Criteria (established primarily for assessment of causation using epidemiological data) that have been the backbone for these efforts. Not surprisingly, application and interpretation of the Hill Criteria in the courtroom has been variable, often resulting in over reliance on epidemiological evidence with a lesser role for the more controlled toxicological studies. From the court’s perspective, there are two types of “causation”: general causation and specific causation. In the former, the court generally need only ascertain that there is a reasonable scientific and/or medical basis to assume that the substance in question is capable causing the alleged injury, illness or disease in order for the case to move forward. Specific causation addresses the issue of a personal injury caused or not caused by a particular drug or chemical within a reasonable degree of scientific or medical prob- 113 MONDAY Program Description (Continued) 45th Annual Meeting and ToxExpo 45th Annual Meeting & ToxExpo Program Description (Continued) ability. Toxicological evidence can play a critical role in establishing both general and specific causation. The panelists will address the strengths and limitations of various types of toxicological and epidemiological data in the context of the causation issue. Issues relating to causation will be discussed from various viewpoints in hopes of providing some insights and clarifications for the bench and for litigants. The three participants in this roundtable are experienced in dealing with these issue both in the courtroom and elsewhere. #717 4:30 TOXICOLOGY IN THE COURTROOM: ESTABLISHING CAUSATION, A ROUNDTABLE DISCUSSION.

CAREER RESOURCE AND DEVELOPMENT SEMINAR: LIFE AFTER YOUR POST-DOC: ADVICE ON FINDING AND LANDING A JOB Sponsored by: Animals in Research Committee* Toxicological research and testing often require the use of animals to investigate mechanisms of toxic action and to accomplish regulatory safety assessments. This animal use must be conducted in accordance with applicable animal welfare laws, policies, and regulations. Additionally, many organizations participate in voluntary accreditation programs, which also necessitates adherence to best practice standards based on guidelines published in the NRC/ILAR Guide for the Care and Use of Laboratory Animals. These requirements and guidelines seek to ensure that investigators use animals in the most humane and judicious manner consistent with successful attainment of the research or testing objectives, and consistent with current best practices for animal care and use. However, institutions face challenges in assuring adherence to best practices in the face of changing research and testing objectives, priorities, techniques, and animal species, such as in response to recent major bioterrorism research initiatives. They are also faced with adhering to evolving changes in best practices for animal care and use in areas such as environmental enrichment, consideration and use of alternatives, humane endpoints, management of pain and distress, and animal caging and environment. This workshop will review the most common animal care and use deficiencies and suggestions for improvement cited by regulatory and accreditation authorities, and the current best practices used as benchmarks by these organizations for inspections and site visits of animal care and use programs and facilities. Perspectives on compliance issues and current best practices will be provided by U.S. DA APHIS/Animal Care (Animal Welfare Act regulations), NIH Office of Laboratory Animal Welfare (PHS Policy on the Humane Care and Use of Laboratory Animals), and the Association for the Assessment and Accreditation of Laboratory Animal Care International. The Canadian Council on Animal Care and the UK Home Office will provide international perspectives. Increased understanding of current animal care and use compliance issues and expected best practices will facilitate optimization of humane animal care and use by investigators and laboratory animal veterinarians, and minimize the likelihood of disruptive mandatory corrective actions.

However, the precautionary principle is receiving increased attention in North America and Europe as a supplement to risk assessment. The foundation of the precautionary principle can be expressed as the commonsense advice to “err on the side of caution.” It is intended to apply to a range of situations that involve both a threat of harm as well as scientific uncertainty. While the PP may seems like common-sense to some to some people, others are concerned the application of the PP will needlessly increase costs and stifle technological advancements. This workshop will start by providing an overview of the PP with historical examples of lessens learned. Next, is an examination of decisions making in the face of the uncertainty that often confronts issues of cause and effect. Alternatives approaches such as green chemistry will be considered.

Further, several California institutions are conducting research to ascertain infant and child-specific vulnerabilities. Researchers will discuss recent work on ascertaining developmental vulnerabilities, particularly those pertaining to the lungs, nervous system, and cancer susceptibility. Evaluation of child-specific vulnerabilities has lead to the listing of 5 child-specific toxic air contaminants, new guidelines for evaluating air risk to infants and children and new standards for particulate matter and ozone. These activities have lead to new proposed guidelines for site mitigation and a reevaluation of water contaminant levels.

MEDICAL RESEARCH COUNCIL (MRC) LECTURE: CELL DEATH AND NEURODEGENERATION Lecturer: Junying Yuan, Harvard Medical School, Boston, MA. The UK Medical Research Council (MRC) sponsored lecture at the SOT Annual Meeting reflects the long tradition of support by the MRC for basic sciences and their translation to medicine. Dr. Junying Yuan will present the MRC lecture on cell death and neurodegeneration. Dr. Yuan is currently a professor of Cell Biology at Harvard Medical School. She initially trained at Fudan University, Shanghai, China and subsequently obtained her PhD in Neuroscience at Harvard University working with the Nobel Prize winner H.R. Horvitz. She continued as an Instructor and Assistant Professor of Medicine at Harvard Medical School, then became Associate and now full Professor of Cell Biology. Professor Yuan has pioneered studies concerning the mechanism of degeneration, regulation and cell death first in C. elegans and then in mammalian systems and has made fundamental contributions by discovering the caspase family of proteases and subsequently by relating them to neurodegenerative conditions. More recently she has used unbiased chemical genetic screens to identify new regulatory machineries controlling the process leading to cell death. She has identified both new death pathways and chemicals that may be used to prevent the onset of non-apoptotic cell death. Her work is of great relevance to cell biology, medicine and toxicology.

The MRC Toxicology Unit was formed in 1947 and is currently located at the University of Leicester where it integrates competitive research areas in cell biology, molecular biology, genetics and medicine. The Unit is pleased to sponsor a lecture at the SOT Annual Meeting to acknowledge the importance of fundamental sciences and its medical applications to the field of toxicology. Tuesday, March 7 8:30 AM to 9:30 AM Room 11A inhaled and nasal drug products (OINDP) that are developed for delivery of drug substance directly to the respiratory or nasal tract to treat either a respiratory or nasal condition, or a systemic disease. Examples of OINDP include metered dose inhalers, dry powder inhalers, solutions/suspensions for nebulization, and nasal sprays. In OINDP, the drug substance is usually contained in a delivery device that may contain polymers, elastomers, and other components from which minute quantities of material may migrate (leach) into the product and be delivered to the sensitive surfaces of the respiratory and/or nasal tract along with the therapeutic agent. While every effort is taken to reduce the levels of these leachables, complete removal is not possible. Because leachables are non-drug-related impurities, there is an increased concern for human risk by inhaling them on a daily basis. Historically, acceptable levels of leachables in OINDP have been set by negotiation with regulatory authorities on a case-by-case basis with no standard guidelines available. Recently, safety thresholds for risk assessment of leachables have been developed through a joint effort of USFDA, academia and industry scientists and have addressed current concepts, background, historical use and development of safety thresholds and their utility in qualifying leachables in OINDP.

Bioluminescent systems will be described that measure the impact of test compounds on xenobiotic metabolizing enzymes, including cytochrome P450s and monoamine oxidase (MAO), and on the multi-drug transporter (MDR1/Pgp). Each system relies on the light generating reaction of firefly luciferase. Pgp-GloTM uses luminescence to measure ATP consumption by the Pgp ATPase. P450-GloTM and MAO-GloTM use a series of selective luminogenic probe substrates for CYP1A1, 1A2, 1B1, 2C8, 2C9, 2C19, 2D6, 2J2, 3A4, 3A5, 3A7, 4A11 and 4F12 and for MAO A and B. These assays are used to measure inhibition of recombinant P450s and MAOs and of native enzymes in liver microsomes. P450-GloTM also provides a novel high throughput method for measuring P450 gene induction at the P450 enzyme level. This suite of homogeneous luminescent assays is sensitive, robust and convenient for small scale and high throughput applications. #731 9:05 CONCEPT, HISTORY AND APPLICATION OF SAFETY THRESHOLDS. D.

Endorsed by: Inhalation SS Regulatory and Safety Evaluation SS* Risk Assessment SS Analytical techniques are sophisticated and capable of detecting and identifying chemicals at picogram quantities. However, it is generally accepted that there are levels of many chemicals below which the risks to human health are so negligible as to be of no consequence. This rationale has been the impetus for development of safety thresholds for regulating chemicals to which humans are exposed. Safety thresholds have a history of use in regulatory applications, most notably in guidelines for food packaging. Recently, such thresholds have been developed for application to pharmaceutical drug products. One of these applications is for leachables in orally up-to-date information at www.toxicology.org 117 TUESDAY number of high-quality papers and is regarded as one of the leading figures in the research field of cell death. 45th Annual Meeting and ToxExpo 45th Annual Meeting & ToxExpo Program Description (Continued) Tuesday, March 7 9:00 AM to 12:00 NOON Room 6E Tuesday, March 7 9:00 AM to 12:00 NOON Room 8 SYMPOSIUM SESSION: RISK ASSESSMENT AND REGULATORY IMPLICATIONS OF CONVULSIVE NEUROTOXICITY SYMPOSIUM SESSION: ROLE OF MITOCHONDRIA IN TOXIC OXIDATIVE STRESS Chairperson(s): Mary Kallman, Eli Lilly & Company, Greenfield, IN and Carrie Markgraf, Schering Plough Research Institute, Lafayette, NJ.

Pharmacology Toxicology Research, Lilly Research Labs, Greenfield, IN. #740 11:00 Considerable experimental and clinical evidence supports the importance of mitochondria and mitochondrial oxidative damage as a critical target and event in toxic oxidative stress-related diseases, including many induced by toxicants. For example, antioxidants such as vitamin E derivatives directed to mitochondria have been shown to protect cells against toxic oxidative stress. Though the critical mitochondrial events responsible for oxidative stress-mediated cell injury and death (toxic oxidative stress) have yet to be defined, oxidative damage to mitochondrial lipids, nucleic acids and proteins appear to be important events in these toxic processes. The purpose of this Symposium is to report recent experimental evidence defining how mitochondrial responses to oxidative stress such as mitochondrial cardiolipin oxidation/depletion, persistent mitochondrial DNA damage and mitochondrial aconitase inactivation can lead to cell injury and death. With a better understanding of the critical molecular events (targets) in mitochondria responsible for toxic oxidative stress, we can look forward to the development of more effective protective therapies.

Tuesday, March 7 9:00 AM to 12:00 NOON Room 1A WORKSHOP SESSION: COMPREHENSIVE RESPONSES OF LIPIDS CLASSES TO TOXICANTS AND INVOLVEMENT IN DISEASES Chairperson(s): Michael Madden, U.S. EPA, Chapel Hill, NC and Ronald Riley, USDA, Athens, GA. Endorsed by: Mechanisms SS Along with genes and proteins, lipids are a key component of the cellular metabolome. Lipids can mediate the induction of some diseases such as atherosclerosis and also responses to some diseases, e.g., asthma. Pollutants such as ozone appear to induce biological responses through altered lipid metabolism. Examining changes in global lipid metabolism, i.e., lipidomics, induced by a pollutant or in a disease state would assist in elucidating the mechanism(s) of responses. Understanding lipid metabolic changes would allow assessment of whether the response was of a highly specific or not, and provide information as to the sensitivity of the lipid measurement, thereby indicating the usefulness as a biomarker. Inherent in this strategy to study lipidomics is the ability to 1) possess a knowledge of the metabolism of 1000 or more lipids in order to optimize lipid study design; 2) measure the lipids in a specific and quantitative manner, including development of new methods to analyze newly discovered species; and 3) transfer of the lipid data to the informatics stage. This session will include presentations with findings related to the topics discussed above. These topics include the structural diversity of lipids, methodologies to quantitate lipid species and classes, how the data from studies examining global changes in lipid metabolism can be processed to allow interpretation of the findings, and the use of endotoxin-exposed macrophages in vitro to validate the lipidomics approach. Another topic that will be presented will be the involvement of oxidized lipids (derived via oxidative stress) in several disease states (cancer, cardiovascular disease). These topics will be presented by five researchers of the LIPID MAPS (Metabolite And Pathways Strategy) Project, which funds investigators at more than 16 academic institutions and 2 corporations to collaboratively research lipidomics using disciplines such as cell biology and organic synthesis.

Endorsed by: Drug Discovery SS* The duration from initial synthesis of a new chemical entity (NCE) to the delivery of an innovative therapeutic to the patient is becoming longer (912 years) with estimated total costs rapidly approaching $1 billion. The financial investment grows exponentially as an NCE advances through the discovery and development process. A major cause of compound failure during the pre-clinical and clinical development phases is toxicity. Estimates regarding toxicology-driven attrition during the drug development process range from 20-40%. Therefore, the opportunity exists for the toxicologist to significantly impact expenditures by the early prediction of potential toxicity/side effect barriers to development by aggressive evaluation of development limiting liabilities early in drug discovery. Improved efficiency in pharmaceutical research and development lies both in leveraging “best in class” technology and integration with pharmacologic and medicinal chemistry activities during hit-to-lead and early lead optimization stages. This workshop will provide an overview of the various strategies being applied to integrate toxicology in the drug discovery process. The presentations will provide a greater understanding of the causes and timing of toxicology-driven attrition in drug development and how the discovery toxicologist can better interface with the pharmacologist and medicinal chemist. Topics which will be covered in detail include in vitro and in vivo screening approaches, the use of high content technologies (i.e., genomics), in silico approaches to predictive toxicology, and the application of alternative animal models (transgenic animals, gene knockdown/knockout models, non-mammalian species, etc.), and finally, examples of integrated discovery toxicology approaches currently being used in the industry. #752 CHALLENGES IN THE ANALYSIS OF COMPLEX MIXTURES OF LIPIDS PRESENT IN BIOLOGICAL EXTRACTS.

A CRITICAL DISCUSSION Chairperson(s): Barbara Beck, Gradient Corporation, Cambridge, MA and Charles Abernathy, Abernathy & Associates, Bristow, VA. Endorsed by: Carcinogenesis SS Metals SS * Risk Assessment SS TUESDAY Considerable controversy exists over the risk assessment of ingested arsenic (As). Various questions include: 1). Should a linear or a nonlinear risk assessment be employed? 2). Do the inorganic and the organic (i.e., monomethyl arsonic acid (MMA) and dimethylarsinic acid (DMA)) arsenicals have similar modes of action? and 3). How much weight should be assigned to the relatively small US studies? In this workshop, the potential of inorganic As and its various metabolites to cause acute and chronic effects to humans and in animal models will be described. Of particular interest will be a contrast of exposures to inorganic As and an organic arsenical, DMA, and discussion of whether such exposures would be expected to result in similar or dissimilar toxic effects via the same or different toxic mechanisms. After considering these questions, the epidemiological data will be evaluated to ascertain how such data can be used to support the theories put forth concerning As toxicity. At the end of the workshop, there will be a question and answer session for the attendees. 9:00 9:10 Tuesday, March 7 9:00 AM to 12:00 NOON Room 1B Tuesday, March 7 9:00 AM to 12:00 NOON Room 5A #758 #759 DOES THE METHYLATION OF INORGANIC ARSENIC AFFECT ITS TOXICITY AND MODE(S) OF ACTION? A CRITICAL DISCUSSION. C. Abernathy. Abernathy Associates, Bristow, VA. Consumer demands for newer and better foods puts considerable pressure on food technicians, and the food industry as a whole, to satisfy this demand for an endless supply of novel food ingredients. Recent developments in ‘fad diets’ and functional claims (i.e., structure function and health) have unlocked new dimensions in food ingredient development. Ingredients never before used or contemplated, such as low carbohydrate starches, new artificial sweeteners, unusual vegetable oils, pre- and probiotic bacteria, and botanical extracts, are now the subjects of intense investigation and development. Adequate demonstration of safety must be driven, by the regulations in place, so that each new ingredient is not evaluated in a de novo or case-specific fashion. The current food ingredient regulations are able to examine macronutrients, modified carbohydrates, oils and proteins, functional (to the human body) ingredients, novel botanical extracts, and competitive bacteria for safety-in-use as a food ingredient. The safety of the food containing a new ingredient can be addressed; however, the role of an individual over-consuming a disproportionate amount of a singular food or food type, i.e., ‘macrofoods/macronutrients, ’ can only be handled by modifications to exposure patterns. Definitions and regulatory status of nutrients, fortificants, functional, and medical foods will be discussed. Additionally, qualified and un-qualified health claims on these and other food ingredients are driving the need to establish efficacy via robust and well-designed clinical studies. Even with these studies in support of the safety and efficacy to human test populations, an adverse event reporting system needs to consider the long-term monitoring of sensitive subpopulations, over-consumption, alternative uses, drug/food interactions, nutrigenomics etc. Finally, the breadth of novel ingredients entering the food supply, and their assessment for safety under the aegis of current regulatory paradigms will be discussed. 120 SOT's 45th Annual Meeting 45th Annual Meeting and ToxExpo 45th Annual Meeting & ToxExpo Program Description (Continued) #764 9:00 9:15 NEW FOOD INGREDIENTS DO NOT NEED NEW FOOD REGULATIONS.

Chairperson(s): Richard S. Pollenz, University of South Florida, Tampa, FL and Robert Tukey, University of California San Diego, LaJolla, CA. Endorsed by: Dermal Toxicology SS Immunotoxicology SS* Regulatory and Safety Evaluation SS Since 2002, adoption of the mouse Local Lymph Node Assay (LLNA) as a stand-alone test to evaluate dermal sensitization potential for industrial chemicals occurred globally (e.g., U.S. EPA OPPTS 870.2600 & OECD TG 429). The LLNA is now endorsed internationally as the preferred, and in some cases mandated, approach replacing the Magnusson and Kligman (M&K) Maximization and Buehler guinea pig methods due to animal welfare benefits, and the use of more objective and quantitative measurements. Moreover, the LLNA lends itself more readily to assess the relative potency of skin sensitizers. This aspect has led to proposals of the LLNA as a possible addition to risk assessment schemes. While years of evaluation using purified, characterized chemicals have suggested the LLNA is overall slightly more accurate than guinea pig tests, its effectiveness at testing novel chemicals since its broad acceptance is beginning to be evaluated. There is little to no published data on the testing of materials such as polymers or complex chemical mixtures.

This analysis can be extended to diseased human tissues in order to understand potential specificity of the drug target providing rapid in silico verification across more than 6000 human diseased tissues. INFORMATIONAL SESSION: CONTRACTING BIOANALYSIS FOR TOX STUDIES AND THE EVOLUTION OF THE COSTING PROCESS Tuesday Afternoon Process by CROs and presented by SFBC International Contracting of bioanalysis essentially began in the 70’s in support of generic ANDAs. In those days it made sense to call a CRO and ask “How much do you charge per sample for HPLC?” Nowadays, tox studies tend to be small and often only a few hundred or fewer samples are analyzed for a given method. If the per-sample cost of bioanlaysis, including the cost of method development and validation, is compared between clinical methods and tox methods the differences can easily be an order of magnitude.

Each year the Colgate-Palmolive Company invites all students and post-doctoral fellows at the SOT Annual Meeting to attend a luncheon and lecture concerning alternative research methods at the forefront of toxicology, specifically, methods that address reduction of use or replacement of whole animals, or the refinement of experimental techniques using whole animal models. Past recipients of all the Colgate-Palmolive SOT awards will be special guests. Students register for this event on the Annual Meeting Registration Form. A $5 deposit per ticket is required and will be returned at the luncheon upon presentation of the ticket. Seating is limited. The lecture will review an important application of in vitro toxicology to the study of basic mechanistic processes and provide examples of how new test methods have benefited animal welfare by refining experimental procedures and reducing animal use. Recent developments in genomics technology now allow for the comprehensive screening of the impact of chemicals and pharmaceuticals on complex cell signaling networks without the use of whole animal systems. The high-throughput requirement of these approaches necessitates use of in vitro cell culture systems. These high throughput screens provide enormous amounts of data in the context of mechanistic and predictive toxicology. The tools for this type of research include a combination of receptor-based reporter gene assays, gene expression analysis using genome-wide microarrays and large-scale, loss-of-function and gain-of-function studies using inhibitory RNA libraries and libraries of full-length genes, respectively. From results obtained with these tools, a cell signaling pathway can be constructed and a more comprehensive and mechanistic understanding of the impact of chemicals on biological systems can be developed. Elucidation of signaling pathways at the cellular level is not possible in intact animals and identification of mode of action at the molecular level is often important in explaining disease states or toxicities identified in vivo. Tuesday, March 7 12:00 NOON to 1:30 PM Marriott Hotel & Marina Cardiff Room SPECIAL INTEREST GROUP MEETING/RECEPTION: HISPANIC ORGANIZATION FOR TOXICOLOGISTS Metabolites can be responsible for the desired efficacy as well as the adverse effects. While qualitatively both phase I and phase II metabolic reactions are fairly conserved across laboratory safety species and humans, there are often important quantitative differences in the rate and the extent of metabolism between safety species and humans. If a metabolite is responsible for toxicity, the quantitative differences in exposure to a major toxic metabolite between humans and laboratory animals can lead to misrepresentation of safety margins based on the parent drug exposure. Non-clinical safety assessment studies are critical to identifying potential toxicity signals for humans and for providing a reasonable assurance related to the test drug’s safety at proposed clinical doses. Given the use of high doses (large multiples of the projected human doses) in safety studies and the fact that the rates of most phase I and phase II reactions are relatively greater in non-clinical safety species than in humans, it is expected that in the vast majority of cases there will be adequate coverage of metabolites both qualitatively and quantitatively in safety studies. In a small number of cases, when the major vs. minor pathways of metabolism are dissimilar across species, there may be human specific “unique” or “dominant metabolites” that may not have been be adequately tested in non-clinical safety studies. The U.S. Food and Drug administration has recently issued “Guidance for Industry: Safety Testing of Drug Metabolites.” The document makes a serious regulatory attempt to define the major human metabolite(s) and provides scientific guidance on the safety testing of the major human metabolites in non-clinical studies. However, the guidance document has also raised ambiguity and concerns regarding the definition of the major metabolites as well as the extent of safety studies with human dominant or unique metabolites. The round-table discussion will provide an academic, industrial and federal regulatory perspective on the proposed guideline, including the definition of the major metabolite and the safety testing of the major metabolites. It is hoped that this scientific round-table discussion will provide a path forward for an adequate testing the safety of metabolites. • Introduction on the Safety Assessment of the Major Metabolites, Rakesh Dixit, Johnson and Johnson PRD, San Diego, CA. • An Academic Perspective on the Safety Testing of the Major Metabolites, Sidney Nelson, University of Washington, Seattle, WA. • An Industry Perspective on the Safety Testing of the Major Metabolites, Alfred Tonelli, Johnson and Johnson, PRD, Raritan, NJ. • The U.S. FDA Regulatory Perspective and the Rationale for the Guideline, M.

Endorsed by: In Vitro SS Reproductive and Development SS Mammalian organisms have long been a staple of toxicology research but in recent years there has been a significant increase in the use of non-mammalian models systems in molecular and developmental toxicology. Alternative model organisms that are in current use include yeast, invertebrates such as Drosophila and Caenorhabditis elegans, vertebrate models such as Danio rerio (zebrafish) and Xenopus, and the pant model, Arabadopsis. The analysis of toxicologically relevant endpoints in these organisms has several advantages over traditional mammalian systems. First, many toxicologically relevant pathways are expressed in each of these organisms that recapitulate the mammalian pathways and full genomes are available. Second, these organisms develop externally and the process proceeds rapidly. This makes it possible to observe development in real-time. Third, due to the size of the organisms, large numbers can be evaluated making high throughput screening studies possible. Finally, many of these organisms have banks of defined mutants that can be manipulated to directly assess protein interactions and gene regulation. Thus, as the molecular tools continue to be advanced for each of these systems, their utility in many aspects of toxicology is unlimited. This session is designed to highlight the use of alternative models in the analysis of signal transduction pathways, development, and genomics.

SYMPOSIUM SESSION: ROLE OF THE KUPFFER CELL IN MEDIATING HEPATIC TOXICITY AND CARCINOGENESIS Chairperson(s): James Klaunig, Indiana University, Indianapolis, IN and Ruth Roberts, AstraZeneca UK, Macclesfield, United Kingdom. Tuesday, March 7 1:30 PM to 4:30 PM Room 8 Endorsed by: Carcinogenesis SS* This symposium will address the role of the Kupffer cell, the resident macrophage of the liver, in the induction and/or facilitation of acute and chronic liver injury. The Kupffer cell plays an important role in the normal physiology and homeostasis of the liver both as well as participating in the acute and chronic responses of the liver to toxic compounds. Activation of Kupffer cells directly or indirectly by toxic agents results in the release of an array of inflammatory and growth control mediators as well as reactive oxygen species. This activation appears to modulate acute hepatocyte injury as well as chronic liver responses including hepatic cancer. Understanding the role the Kupffer cell plays in the induction of hepatocyte injury is essential in understanding the mechanisms of the liver injury. Idiosyncratic drug induced liver disease results in morbidity and mortality and has been a major detriment to new therapeutic pharmacological development. Modulation of the Kupffer cell response by drugs has been suggested as a cause for the idiosyncratic response. Similarly, liver damage seen in chronic ethanol consumption appears to be modulated by Kupffer cell activation. More recent evidence has noted a contributory role of Kupffer cell activation in the process of hepatic carcinogenesis. Several nongenotoxic carcinogens, for example, activate Kupffer cells which results in the release of cytokines and/or reactive oxygen species that induce hepatocyte cell proliferation and may enhance clonal expansion of preneoplastic cells leading to neoplasia. The Kupffer cell therefore appears to play a central role in the hepatic response to toxic and carcinogenic agents.

Endorsed by: Biological Modeling SS Regulatory and Safety Evaluation SS* Risk Assessment SS Social demands to ensure public health and safety from either planned or accidental exposure to new molecular entities whilst still maintaining a flow of new and more effective medicines or the necessary commercial advances in personal products, requires both industry and regulatory authorities to identify and manage the risks presented by an increasingly large number of novel compounds. Often these initial assessments are made in the absence of high quality toxicology data and generating this data would take many years and millions of dollars for each compound under review. As a result, the scientific community has been seeking ways to prioritize these new and existing chemical entities according to their potential for adverse effects to either humans or the environment. Structure-based approaches to hazard identification and risk assessment offer significant advantages for both industry and regulator alike but their application is not without its drawbacks. On the positive side, these types of approaches to hazard assessment are very fast and cheap to run once they have been successfully implemented. In addition, these approaches offer a highly attractive public relations solution in view of the increasing demands to refine, reduce or replace animals in laboratory experiments. However, questions still exist about their ability to accurately distinguish between toxic and non-toxic molecules and their effectiveness in ensuring public safety. This symposium will highlight recent experiences and learnings in the practical application of structure-based hazard identification and/or risk assessment across a broader scope of industry and regulatory agencies. The presentations will illustrate how structure-based assessments are being applied towards a variety of potential hazards (genetic toxicity, 149 TUESDAY #1120 45th Annual Meeting and ToxExpo 45th Annual Meeting & ToxExpo Program Description (Continued) carcinogenicity, skin sensitization, etc.) and how this information is being used to aid in decision-making (e.g. development, risk management, exposure controls, prioritization of biological testing). #1128 1:30 USING STRUCTURE-BASED APPROACHES FOR HAZARD IDENTIFICATION AND RISK ASSESSMENT.

This is presumptive, but based upon the potential for cells and tissues injured during the initial insult to become more, or perhaps even less, susceptible to additional injury by a subsequent insult. As a mechanistic explanation for lung injury, O3 and other air pollutants are known to react with cell membranes within the respiratory tract and initiate a direct response through oxidative actions. The destruction of protective mechanisms, either by a direct action of oxidants in the air or through the effects of inf lammatory mediators, offers an explanation for the altered susceptibility to complex atmospheres or upon repeat exposures. Epidemiological studies have also identified greater vulnerability of sensitive populations, such as the children, the elderly and individuals with cardiopulmonary conditions, to air pollutants. It is suggested that high ozone levels in the air substantially increase the risk of illness and death for compromised individuals. Clearly, the role of ozone in the toxicity of air pollution can not be ignored. A need for reevaluation of current air quality standards for ozone is recognized, and there is a growing interest in understanding its contribution to the development of chronic lung disease. With ozone as the focus, the symposium will address the above issues, by discussing ozone dosimetry, developmental status of the respiratory system, cellular and inflammatory mechanisms of lung injury, human health effects, sensitivity of susceptible populations, modification of particle toxicity in mixed atmospheres and future directions.

Differential gene expression after exposure to a toxicant will allow for the determination of potential biomarkers of toxicity. These array-based biomarkers should enable the detection of changes at a very early stage in the progression of toxicant-induced adverse health effects. The realization of these promises, however, depends on careful validation, statistical analysis, and corroboration of genomic responses with responses in the intact organism. Thus, new informatics and analytical methods as well as large integrated databases are being developed to interpret the vast amount of biological data and turn it into useful information. Although these technologies are in the developmental stages, both the U.S. EPA and the USFDA have developed draft guidances and policies that recognize that these data will ultimately be part of science-based safety and risk assessment decisions. Initially, genomic data shows promise in the characterization of chemical-specific mode of action (MOA) and in the description of toxicity pathways that result in adverse health effects. This workshop will present potential approaches on how genomics could be used to fill data gaps in the characterization of the MOA used in the assessment of risk posed by environmental chemicals.

Endorsed by: Food Safety SS* Regulatory and Safety Evaluation SS Reproductive and Development SS Risk Assessment SS Tuesday, March 7 1:30 PM to 4:30 PM Room 1B PLATFORM SESSION: APOPTOSIS In recent years, decreased sperm count and increased breast cancer rates have claimed to be associated with man-made and dietary (phyto-) estrogens. Several additives used in foods and other consumer products, such as isoflavones, UV screens, certain alkylphenols, bisphenol A, some parabens and certain phthalates have been shown to be weakly estrogenic in in vitro or in vivo assays. As these chemicals are widely and increasingly used, there is a growing concern as to their role in reproductive toxicity and breast cancer. Recent findings on the presence of parabens in human breast cancer tissue samples have ignited the debate on the role of estrogenic food additives in the development of cancer and reproductive toxicity. These findings and dilema created have raised the level of concern with both consumers and industry. This movement is spreading to a wider audience, whether there is any basis for concern or not. Several of the food additive estrogens are also consumed as part of a natural food, however it is not known what effects may be produced when consumed in isolated/ concentrated/ purified form. The current risk assessment of estrogenic substances as food additives is performed individually and combined effects of these substances in the diet are not known. As these substances share a common mechanism of action, an aggregate risk assessment for each chemical in the group and a cumulative risk assessment is needed. Additionally, the contributions of ingredients with antiestrogenic activity in the diet also needs due considerations. Should the estrogenic substances be added to foods/consumer products and if so at what levels? #1151 TUESDAY #1152 1:30 1:35 Chairperson(s): Valerian Kagan, University of Pittsburgh, Pittsburgh, PA.

(Con) SOT: Dan Nebert, University of Cincinnati, Cincinnati, OH. The 2006 Eurotox debate continues a very informative series in which the points and respective counterpoints on a given topic are addressed by well known toxicologists. Dr. Daniel W. Nebert and Prof. Alan R. Boobis will present differing views on the contribution of ‘omic’ technologies for assessing chemical safety as it applies to assessing human risk. Wednesday, March 8 8:30 AM to 9:30 AM Room 11B INFORMATIONAL SESSION: CARDIAC SAFETY—CURRENT THINKING WHEN APPROACHING SAFETY ASSESSMENT STUDIES Presented by Covance Adverse effects on cardiac safety have been responsible for several highprofile withdrawals, denied regulatory approvals and adverse labeling in human pharmaceuticals in recent years. This session will present current thinking on the electrophysiology of drug-induced QT prolongation, and a rational approach to the pre-clinical assessment of drugs for their potential to produce this unwanted, and potentially dangerous, side effect. The second most common birth defect is neural tube defects (NTDs). In Guatemala, parts of China and Africa, NTD risk is estimated to be higher than that observed in the USA. The etiology of NTD in these areas is complex. Increased risk has been associated with genetic predisposition, dietary exposure to environmental contaminants, and reduced intake of folate and other vitamins/nutrients. Human clinical and epidemiological studies show folate supplementation reduces the risk for NTDs. Fumonisins are carcinogenic mycotoxins that cause farm animal diseases. They commonly contaminate maize and are suspected, but not proven, to cause human disease. Their mode of action involves inhibition of the enzyme (ceramide synthase) that controls the formation of sphingolipids; important regulators of pathways involved in cell death and survival. Sphingolipids are needed for the proper function of receptors associated with lipid rafts; for example, the folate-binding protein (Folbp1). Fumonisin disruption of folate transport via Folbp1 interferes with neural tube closure in animal models in vitro and can be prevented by folate supplementation. In vivo studies in LM/Bc and CD1 mouse strains have found that maternal fumonisin administration during pregnancy increases the frequency of NTD in exposed embryos. Supplementation with folate or ganglioside GM1 is protective, suggesting altered sphingolipid-dependent lipid raft function. In addition, altered expression of cytokines, inducible nitric oxide synthase, and several genes involved in redox homeostasis are observed in affected embryos. While there is no direct evidence for fumonisin as a cause of NTD in humans, the incidence of NTD is higher where maize consumption is high and both fumonisin exposure and folate deficient diets are likely. Epidemiological studies and further experimentation with animal models will be necessary to assess the teratogenic potential and impact of fumonisin as a human health hazard. #1492 9:00 GENE-NUTRIENT-ENVIRONMENT INTERACTIONS AS RISK FACTORS FOR BIRTH DEFECTS: FUMONISIN, FOLATE, GENETIC VARIATION AND NEURAL TUBE DEFECTS.

Endorsed by: Immunotoxicology SS* Inhalation SS Occupational and Public Health SS Occupational asthma is defined as variable airflow limitation and bronchial hyperresponsiveness due to causes and conditions encountered in a workplace environment. A myriad of substances are responsible for occupational asthma, including low molecular weight chemicals and protein allergens. Though asthma is treated as a single lung disorder, it is increasingly clear that the pathophysiology of asthma may differ substantially depending on the allergen, exposure conditions and environmental triggers. Diagnostic, immunologic and genetic factors associated with disease development are being actively investigated. Animal models for occupational asthma are being developed to define mechanisms of this lung disorder and determine more effective methods for prevention, diagnosis and treatment of occupational asthma. Both toluene diisocyanate and trimellitic anhydride are prototype low molecular weight chemicals that cause asthma in the workplace, and studies defining the effector mechanisms for these allergens are being investigated. Environmental factors such as ozone and particulate air pollution can exacerbate existing asthma and profoundly influence the pathophysiology and clinical outcome. Understanding the interactions of environmental and genetic factors is also important to define potential populations at risk. Continued studies in the workplace and in animal models are needed to more clearly diagnose, define the pathophysiology and triggers, and effectively treat this important public health problem.

Wednesday, March 8 9:00 AM to 12:00 NOON Room 6C SYMPOSIUM SESSION: OBESITY AS A MODULATOR OF CHEMICAL TOXICITY Chairperson(s): Chris Corton, U.S. EPA, Chapel Hill, NC. Endorsed by: Mechanisms SS* Obesity as a Modulator of Chemical Toxicity In the last few decades the overweight and obese in the US have grown from a relatively minor subpopulation to ~60% of all adults. Even more alarming is the dramatic increase in the number of overweight and obese children. This obesity epidemic is linked to increases in the incidences in cardiovascular disease, diabetes mellitus and certain forms of cancer. Adipose tissue is no longer considered a static depot of excess energy reserves but an endocrineactive tissue. Increases in adipose tissue, particularly abdominal fat lead to features of insulin resistance syndrome, also referred to as metabolic syndrome X. This syndrome consists of a clustering of metabolic abnormalities that increase the risk for type 2 diabetes and cardiovascular disease. Adipose tissue also secretes a number of cytokines leading to a low inflammatory state in the obese. Additionally, obesity is associated with higher levels of insulin, insulin-like growth factor I and oxidative stress that are mechanistically linked to carcinogenesis. Given that chemical toxicity is often dependent on the same factors that are at increased levels in the obese, obesity may lead to an environment of increased sensitivity to chemical-induced toxicity. In this symposium, the physiological, biochemical and molecular mechanisms that lead to metabolic syndrome X and changes in growth factors and cytokine secretion in the obese will be 180 SOT's 45th Annual Meeting 45th Annual Meeting and ToxExpo 45th Annual Meeting & ToxExpo Program Description (Continued) #1503 9:00 OBESITY AS A MODULATOR OF CHEMICAL TOXICITY.

Zn induces activation of ERK1/2, JNK and p38 and the tyrosine kinase receptor, EGFR. Modulation of ERK1/2 and EGFR involves multiple levels of activation, including EGFR transactivation by Src and metalloprotease activation. Finally, other studies on airway epithelium have examined signaling pathways by which Cr(VI), at non-cytotoxic concentrations, selectively induces and silences genes. Cr stimulates Src family kinases (SFK) Lck and Fyn, but not Src or Yes, and stimulation of SFKs leads to selective activation of JNK. However, although Cr induces ROS generation, SFK-dependent JNK activation occurs independent of metal-induced oxidative stress. OBESITY, METABOLIC SYNDROME X AND INFLAMMATION. P. Dandona.

Endorsed by: Inhalation SS Mechanisms SS Metals SS* Mitogen-activated protein kinases (MAPKs) may mediate the cytotoxic responses and cytoprotective mechanisms elicited by metals, such as Zn, Cd, Cr, and As. The session will open with a review of the common and unique biochemical properties of MAPK family members, ERK1/2, ERK5, JNKs, and p38 proteins, activation of each MAPK cascade by selective stimuli, and the respective down stream targets in the context of their physiological function. A common cellular response to exposure to various metals is an altered redox state. The second talk will address direct activation of MAPKs by oxidants, such as hydrogen peroxide, and electrophiles, such as 4-hydroxy-2-nonenal (HNE), an end product of lipid peroxidation. A highlighted example of MAPKs as mediators of cytoprotective mechanisms recruited in response to oxidative stress will be HNE-induction of g-glutamyl transpeptidase via ERK1/2 and p38 and of glutamate-cysteine ligase via JNK, two responses critical to adaptive increases in GSH. The third talk will address MAPKs as mediators of cytotoxic responses triggered specifically by metal-induced oxidative stress. For example, Cr(VI) at toxic concentrations, via ERK1/2 and p38, upregulates p21 and cdc2 and causes degradation of cdc25C, leading to growth arrest at G2/M.

Endorsed by: Biological Modeling SS Occupational and Public Health SS There is a need to develop sensitive and novel approaches that can be used for biological monitoring of both occupational and environmental exposures to a broad-range of chemical agents, and to rapidly determine the potential implications of these exposures to human health. This symposium 181 WEDNESDAY discussed. A number of examples in rodent models will be given, in which obesity clearly alters chemical toxicity in a number of tissues. The information presented in this symposium will highlight the fact that the obese should be evaluated as a sensitive population. 45th Annual Meeting and ToxExpo 45th Annual Meeting & ToxExpo Program Description (Continued) will highlight technology that focuses on the application of bio-analytical chemistry for assessing low level chemical exposure, coupled to the development of sensitive, selective, rapid, and cost-effective sensors for toxicity screening, biomonitoring, and development of field deployable platforms. These approaches can be applied to identify novel biomarkers in experimental animal model systems and in humans using a range of readily obtainable biological matrices. Finally, through the application of advanced computational modeling it may be possible to quantitatively determine dosimetry. The first speaker will focus on approaches for quantifying biomarkers of low-level chemical exposures in biological samples obtained from epidemiology studies using mass spectrometry isotope dilution. The second and third speakers will highlight ongoing research focused on the development of cost-effective toxicity screening methods, and the application of immunoassay based biosensor platforms for biomonitoring. The final two speakers will highlight the potential application of these high resolution analytical approaches and sensor technologies to assess chemical exposures in real-time through the direct analysis of exhaled breath or saliva for a range of agents including organic solvents, heavy metals, insecticides, and the application of physiologically based pharmacokinetic models to assess total exposure and internal target tissue dosimetry. The presentations in this symposium will provide important insight on the value of integrating quantitative sensor technology with traditional biological monitoring approaches to advance our capabilities for chemical exposure biological monitoring and modeling. #1515 9:00 ADVANCED TECHNOLOGIES AND APPROACHES FOR QUANTITATIVE BIOMONITORING FOR CHEMICAL EXPOSURES.

Endorsed by: Carcinogenesis SS Inhalation SS Neurotoxicology SS Risk Assessment SS* Temperature is a fundamental factor influencing all aspects of biological systems. Perhaps because of its simplicity and ubiquitous nature, changes in body temperature are often overlooked, or minimized, when assessing the toxicity of chemicals, air pollutants, toxins and pharmacologic agents. Rodents in particular can respond to acute xenobiotic exposure with a regulated reduction in core body temperature (hypothermia) which can have a major impact on physiological and biochemical processes of the organism. This acute response is generally beneficial to the animal because supportive measures to prevent the drop in core body temperature can decrease survival. The impact of toxicant-induced hypothermia is not limited to acute toxicologic endpoints. Micronucleus formation is routinely used to establish the potential mutagenicity of a test material. However, hypothermia alone can increase micronucleus formation, confounding the interpretation of the mutagenic activity attributed directly to the toxicant from that of the toxicant-induced adaptive hypothermic response. While hypothermia is the predominant thermoregulatory response to toxicantexposure in rodents, hyperthermia is a frequent observation in humans following acute exposure to a variety of toxicants. Because humans do not respond similarly to exposure to toxic agents data extrapolation can be confounded, increasing the uncertainty of the risk assessment process. Given the complexity and divergence of these physiologic responses, toxicity data derived from exposures in rodents should be considered in the context of any chemical-induced effects on thermoregulation in order to improve predictions of potential human toxicity. This workshop should be of interest to experimental toxicologists in all disciplines, as well as individuals involved with pharmaceutical development, human risk assessment, and product regulation and registration.

Dearman and I. Kimber. Syngenta, Macclesfield, United Kingdom. up-to-date information at www.toxicology.org Manganese is essential for normal physiological function in humans. However, occupational or environmental exposures to excess levels of manganese are associated with adverse effects on the central nervous system. Human exposure to manganese varies depending on geographical location, urban or rural environment, diet, and importantly, occupational settings. Furthermore, acute or chronic exposure to different chemical forms of manganese may occur at different life-stages. These factors along with diverse genetic composition are likely to impart differential sensitivity of individuals to manganese neurotoxicity. This symposium is meant to identify the contribution of modifiers such as age, nutritional status and genetics, to the vulnerability of individuals to manganese neurotoxicity. Speakers will detail advantages offered by invertebrate animal models in deciphering the mechanisms and genetics of manganese neurotoxicity. The role of diet in particular iron deficiency will be discussed in relation to manganese transport into cultured brain endothelial cells and regional brain distribution. Behavioral, neuroimaging and pathological endpoints will be described in a non-human primate model of chronic manganese exposure. These studies are prospective in nature and follow in parallel the effects of manganese exposure on cognitive and motor function and neurochemical changes in the living brain. Finally, biomarkers for the human diagnosis of early manganese exposure will be highlighted. The multidisciplinary nature of the symposium, bringing together scientists with expertise in behavioral, molecular, brain imaging and human population studies, is aimed at providing a comprehensive state-of-the-art account of recent advances in the fast-paced research area on manganese neurotoxicity. 207 #1842 1:30 DETERMINANTS OF MANGANESE NEUROTOXICITY: FROM WORMS TO MEN.

WEDNESDAY Allergy is a diverse family of diseases that continues to provide important and substantial challenges for toxicology and occupational and environmental medicine. Skin sensitization, resulting in allergic contact dermatitis, represents the most common manifestation of immunotoxicity in humans, and the prevalence of atopic allergy has increased significantly in the USA and Europe. In recent years there have been impressive advances made in the identification and characterization of chemicals and proteins that have the potential to cause allergic sensitization, and in the development of improved approaches to risk assessment. However, there remains considerable uncertainty about the factors that determine well-documented inter-individual differences in susceptibility to chemical and protein allergy. The purpose of this Symposium is to review new and emerging information on the cellular and molecular mechanisms responsible for heritable and acquired differences in susceptibility to allergic diseases. 45th Annual Meeting and ToxExpo 45th Annual Meeting & ToxExpo Program Description (Continued) #1845 #1846 #1847 2:45 3:20 3:55 COGNITIVE AND MOTOR EFFECTS OF CHRONIC MANGANESE EXPOSURE IN NON-HUMAN PRIMATES.

Endorsed by: Toxicologic and Exploratory Pathology SS* WEDNESDAY Although our understanding of the processes underlying the pathogenesis of particle-induced lung disease has greatly improved over the years, questions still remain regarding the issues of species differences in response to inhaled particles, the mechanisms underlying these differences, and their impact on human hazard evaluation and risk assessment processes. Poorly-soluble particles (PSP) have several common characteristics: they are low in solubility, have low toxicity, and are non-mutagenic and non-genotoxic. Numerous inhalation studies in rodent species have been conducted to assess the dose-related toxicity of these PSP (e.g. carbon black, titanium dioxide, talc, and coal and shale dusts). Studies conducted in rats have demonstrated that chronic inhalation of high doses of these materials results in increased pulmonary inflammation, fibrosis, epithelial hyperplasia, and, in some cases, adenomas and carcinomas in the peripheral rat lung. This response is generally referred to as an overload response or threshold effect. The hypothesis that a threshold effect is relevant to the tumor response in rats is supported by data from numerous studies indicating that at exposure levels below that which causes a persistent inflammatory response, tumors are not produced. Substantial data also indicates the involvement of secondary processes, such as inflammation and inflammatory-induced oxidative stress, as possible mechanisms for the rat lung tumor response. Furthermore, recent studies have highlighted the impact of particle size and surface area on these processes. Along with the effects observed in the lower respiratory tract, it has recently become apparent that nasal tissue is also an important target for particle-induced toxicity. The current information regarding the roles of particle surface area, tissue retention, and chronic inflammation in response has contributed to an improved mechanistic understanding of the rat lung tumor response to Wednesday, March 8 1:30 PM to 4:30 PM Room 6C SYMPOSIUM SESSION: THE PATH FOR ASSESSING HUMAN RELEVANCE AND ADVANCING NEW SAFETY BIOMARKERS FOR DRUG-INDUCED VASCULAR INJURY Chairperson(s): Denise Robinson, Pfizer Global Research & Development, New London, CT and Frank Sistare, Merck & Co Inc., West Point, PA. Endorsed by: Mechanisms SS Regulatory and Safety Evaluation SS* Risk Assessment SS Treatment related vascular injury is a significant pre-clinical safety issue for the pharmaceutical industry. Noninvasive methods for early detection in animal studies and for monitoring patients to assess in clinical trials the human relevance of pre-clinical findings remain a vital unmet need. The observation of vascular injury during toxicity testing in animals, may stop or delay compound development and/or limit the allowable clinical dose range, thereby limiting the development or the therapeutic uses of a product. The clinical advance of compounds that produce 208 SOT's 45th Annual Meeting 45th Annual Meeting and ToxExpo 45th Annual Meeting & ToxExpo Program Description (Continued) vascular injury pre-clinically has also been slowed by the lack of clear regulatory guidance. Sensitive and specific biomarkers as well as experimental approaches that provide a better understanding of the mechanisms that produce vascular injury in pre-clinical models, are needed to assess relevance for human risk, to manage the risk rationally, and ensure clinical trial safety. Just as important as the science is the process for gaining scientific and regulatory acceptance around the validity and appropriate clinical investigative application of any such new biomarkers. This session will highlight the latest advances in our mechanistic understanding of the pathways of vascular injury in various pre-clinical models, and introduce novel approaches to assessing and monitoring vascular compromise. The focus will be on what we can do with what we know now, given the regulatory impetus to drive the qualification and application of new biomarker technologies for safety assessment. 1:30 THE PATH FOR ASSESSING HUMAN RELEVANCE AND ADVANCING NEW SAFETY BIOMARKERS FOR DRUG INDUCED VASCULAR INJURY.

Endorsed by: Carcinogenesis SS Mechanisms SS Molecular Biology SS Reproductive and Development SS* There is increasing evidence that some environmental agents, especially those with endocrine agonist or antagonist activity, may alter developmental programming via alteration in gene expression that do not result in malformations but in functional deficits. These functional deficits in tissue potential are expressed later in life as increased susceptibility to disease/dysfunction. In some cases the functional deficits have been shown to be transmitted to the next generations(s). The mechanism proposed for this phenomenon, termed the fetal basis of adult disease, is believed to be epigenetic alterations in gene expression probably via altered DNA methylation. The talks in this session will highlight examples of in utero exposures resulting in increased diseases later in life. In some instances transgenerational effects due to in utero exposures to environmental agents can be shown. An overview of epigenetics with an emphasis on how it might contribute to the adult diseaases and the transgenerational effects of these in utero exposures will also be presented.

Chairperson(s): Dennis Paustenbach, ChemRisk Inc., San Francisco, CA and Jennifer Pierce, ChemRisk Inc., San Francisco, CA. Wednesday, March 8 1:30 PM to 4:30 PM Room 7A Endorsed by: Biological Modeling SS Ethical, Legal, and Social Issues SS Risk Assessment SS Hormesis remains a controversial topic in the fields of toxicology and risk assessment. The reason, is that if the phenomenon generally exists for all toxic effects and all chemicals, this would put current approaches to regulating chemicals into question. For carcinogens, there would need to be a re-evaluation of the current view that the linear dose-response relationship is most appropriate, and instead, a biphasic model would probably be considered most appropriate (with inclusion of a threshold). In addition, some chemicals with carcinogenic effects might reduce risk for cancer at certain exposure levels. For the chemicals whose most sensitive adverse effects are not cancer, a change in the approach for identifying the No Adverse Effect Level (NOAEL) would be necessary. This symposium will provide a comprehensive overview of hormesis, and its potential impacts on risk assessment and regulatory policy, as well as its impact on chemotherapeutics. The legal hurdles to implementing such an approach will be discussed. In addition, the various changes in toxicology testing protocols that would be necessary to insure that hormesis is incorporated into regulatory decision making will be discussed. The practical consequences of adopting the concept of hormesis, specifically with respect to the remediation of contaminated sites, setting of drinking water standards, and other regulatory risk criteria will be described. A physician will discuss the impact of hormesis on future biomedical and clinical research. The goal of this symposium is to bring together perspectives on this topic from various fields, and initiate a dialogue between those in support of and against the adoption of the hormetic dose-response model. Further, it will provide the toxicology community with the knowledge of one of the most contemporary, yet historically rooted debates among the scientific community. #1865 1:30 HORMESIS: A CHALLENGE TO THE LINEAR DOSE-RESPONSE MODEL, AND ITS IMPLICATIONS IN RISK ASSESSMENT, REGULATORY POLICY, AND BIOMEDICAL RESEARCH.

WORKSHOP SESSION: INTEGRATING BIOMONITORING INTO EPIDEMIOLOGY AND TOXICOLOGY RESEARCH Chairperson(s): James Bus, Dow Chemical Company, Midland, MI and Leonard Ritter, Canadian Network of Toxicology Centres, Guelph, ON, Canada. Endorsed by: Biological Modeling SS Epidemiology has well established methods for conducting research using questionnaires on self-reported exposure. Categories of exposure and intensity algorithms have been developed to determine the dose response of the putative health effect. Toxicology has also developed sophisticated pharmacokinetic models and dosing methods by which to evaluate hazards of specific chemicals or pesticides. Between the two disciplines epidemiology and toxicology, however, lies a growing body of biomonitoring data capturing real-world human exposures. Emerging data from both the CDC National Exposure Report and other similar studies presents an opportunity to better integrate complex exposure/dose metrics into improved evaluations of human health risks. The objectives of this workshop will examine several key questions addressing this task. A critical weakness in modern epidemiology is the lack of validation of exposure. Can survey methodology in agricultural epidemiology studies be improved from information obtained from recent exposure biomonitoring studies of farmers? How can detected levels of chemicals in the human population be better corresponded to dose/exposure metrics in animal toxicology studies so that findings of biomonitoring studies can be better related to potential adverse health outcomes? Lastly, how can biomonitoring, epidemiology and pharmacokinetic tools be improved to better link traditional external exposure measures to actual measures of internal tissue doses? 210 #1871 1:30 INTEGRATING BIOMONITORING INTO EPIDEMIOLOGY AND TOXICOLOGY RESEARCH.
