Epigenetics is a term in biology referring to heritable traits that
do not involve changes in the underlying DNA sequence of the
organism. Epigenetic traits exist on top of or in addition to the
traditional molecular basis for inheritance. The "epigenome" is a
parallel to the word "genome," and refers to the overall epigenetic
state of a cell. Cancer and stem cell research have gradually
focused attention on these genome modifications. The molecular
basis of epigenetics involves modifications to DNA and the
chromatin proteins that associate with it. Methylation, for
example, can silence a nearby gene and seems to be involved in some
cancers. Epigenetics is beginning to form and take shape as a new
scientific discipline, which will have a major impact on Medicine
and essentially all fields of biology. Increasingly, researchers
are unearthing links between epigenetics and a number of diseases.
Although in recent years cancer has been the main focus of
epigenetics, recent data suggests that epigenetic plays a critical
role in psychology and psychopathology. It is being realized that
normal behaviors such as maternal care and pathologies such as
Schizophrenia and Alzheimer's might have an epigenetic basis. It is
also becoming clear that nutrition and life experiences have
epigenetic consequences. Discover more online content in the
