Epigenetics Special Section

Epigenetics is the the study of changes in organisms caused by modification of gene expression rather than alteration of the genetic code itself. The DNA modifications considered by epigenetic researchers are related to how external factors affect gene expression without altering the DNA sequence.  Identifying the mechanisms by which these genes are suppressed or expressed has become a hot topic within the research community because of its potentially significant impacts, such as controlling genes associated with cancer and Alzheimer’s disease. This special section covers some of the research going on today.
