AbstractEpigenetics describes heritable alterations of gene expression that do not involve DNA sequence variation and are changeable throughout an organism's lifetime. Not only can epigenetic status influence drug response, but it can also be modulated by drugs. In this review, the three major epigenetic mechanisms are described: covalent DNA modification, histone protein modification, and regulation by noncoding RNA. Further, this review describes how drug therapy can influence, and be influenced by, these mechanisms. Drugs with epigenetic mechanisms are already in use, with many more likely to be approved within the next few years. As the understanding of epigenetic processes improves, so will the ability to use these data in the clinic to improve patient care.© 2013 Pharmacotherapy Publications, Inc.
