Why should you care about epigenetics? What’s the easiest way to
Why should you care about epigenetics? Why do some foods cause health problems and others make us healthy? How does stress impact our long-term well-being? Why is it that the older we get, the more likely it is that age-related illness will strike us? Unlocking the secrets behind these and other questions has the potential to revolutionize life as we know it. The emerging field of epigenetics is aiming to do just that. The importance of nature versus nurture has long been disputed. It cannot be denied that environment greatly influences how a child grows and develops, nor can it be denied that our DNA is the blueprint that makes us who we are. Epigenetics merges these two seemingly contradictory lines of thought to explain how environmental factors cause physical modifications to DNA and its associated structures, which result in altered functions. The most commonly known epigenetic modification is DNA methylation. Although many technologies have been developed in the past to characterize genomic DNA methylation, none of them has been able to efficiently determine DNA methylation patterns on a genomic scale. Until now. What’s the easiest way to discover your next biomarker? Rapid advances in bisulfite chemistries, library methods, and sequencing platforms have revolutionized the field of biomarker discovery and analysis. Zymo Research is proud to offer the first consolidated service for tackling the exciting challenge of epigenetic biomarker discovery. EpiQuest™ Services are a customizable family of processes tailored to the individual researcher, allowing for more robust analysis of the methylome than ever before.

Next-Gen Sequencing To date, epigenetic modification of DNA has been most closely associated with detection and quantitation of 5-methylcytosine (5-mC). The so-called “fifth base” has become a springboard for the study of the closely related 5-hydroxymethylcytosine (5-hmC). The modified base is speculated to be an intermediate in oxidative demethylation pathways, but could itself constitute a new layer of epigenetic regulation, gaining attention in recent years as a potential epigenetic factor in fields ranging from ES-cell renewal and cell mass specification (Ito et al, 2010) to several myelodysplastic pathologies (Lorsbach et al, 2003).

Development & Stem Cells Cancer Aging The development of an organism is dictated by precise gene expression. Epigenetics, especially DNA methylation, is a critical factor in the development process. Following fertilization of the egg, a wave of DNA demethylation is followed by remethylation events to “reprogram” the maternal and paternal genomes for proper zygote development. Accordingly, misregulation of these epigenetic factors can result in developmental abnormalities. Therefore, research focused on the mechanisms and roles of DNA methylation/ hydroxymethylation in development should be essential for understanding developmental and stem cell biology. Cancer has conventionally been considered a genetic disorder. However, recent research has demonstrated epigenetic factors to be important in cancer biology. Aberrant DNA methylation (5-mC) and potentially hydroxymethylation (5-hmC) can result in the misregulation of gene expression (e.g., silencing of tumor suppressors and activating oncogenes), chromosomal instability, and mutations. A better understanding of the relationship between epigenetic regulation and cancer will be necessary for greater advances in the understanding of both processes and in the development of cancer therapies. Aging is an inevitable part of life. DNA methylation patterns are known to change with age. Recent research has found that methylation at specific loci can be used as a predictor of a patient’s age. Also, age associated diseases (e.g., cancer, Alzheimer’s, etc.) can be correlated with shifts in DNA methylation. An understanding of how DNA methylation and age are correlated should give insight into the processes of aging and disease. The search for epigenetic modifiers...
