Epigenetics and diabetic cardiomyopathy

Abstract

Cardiovascular complications are a chief cause of mortality and morbidity in diabetic patients. Recent studies suggest that epigenetic changes which may arise as a consequence of environmental factors play an important role in predisposition to disease. Epigenetic mechanisms such as DNA methylation, chromatin remodeling and histone modifications regulate the gene expression in response to environmental signals. Role of epigenetics has been recognized in the pathology of diabetes, however its role in diabetic associated cardiomyopathy remains largely unexplored. In this article, we review current literature on the epigenetic mechanisms involved in diabetes and discuss recent evidence of epigenetic changes that may play an important role in pathophysiology of DCM.
