Epigenetics : principles and practice
Copyright © 2011 S. Karger AG, Basel..
Epigenetics is defined as heritable changes in gene expression that are, unlike mutations, not attributable to alterations in the sequence of DNA. The predominant epigenetic mechanisms are DNA methylation, modifications to chromatin, loss of imprinting and non-coding RNA. Epigenetic regulation of gene expression appears to have long-term effects and wide-ranging effects on health. Diet and environmental exposures may potentially alter the level and scope of epigenetic regulation, thus interesting developments in the study of epigenetics might explain correlations that researchers have found between lifestyle and risk of disease. Aberrant epigenetic patterns have been linked to a number of digestive diseases including Barrett's esophagus, cirrhosis, inflammatory bowel disease, and numerous gastrointestinal malignancies. In fact, many exciting discoveries about epigenetics in general have been made by studying diseases of the gastrointestinal tract and hepatobiliary tree. Epigenetic modifications of DNA in cancer and precancerous lesions offer hope and the promise of novel biomarkers for early cancer detection, prediction, prognosis, and response to treatment. Furthermore, reversal of epigenetic changes represents a potential target of novel therapeutic strategies and medication design. In the future, it is anticipated that innovative diagnostic tests, treatment regimens, and even lifestyle modifications will be based on epigenetic mechanisms and be incorporated into the practice of medicine.
