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 future of epigenetic
research?
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).

How does epigenetics play a key role in your research?
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.
