The epigenome and its role in diabetes.
Both genetic and environmental factors play critical roles in the development of diabetes. Epidemiological evidence and data from clinical studies suggest the persistence of a "metabolic memory" of past exposures to environmental factors or glycemic control. Epigenetic mechanisms are regarded as one of the likeliest candidates underlying these phenomena. On the other hand, owing to the recent elucidation of mechanisms that erase epigenetic marks, it has gradually become recognized that epigenetic regulation is a more dynamic process than previously thought. A technological breakthrough in epigenome research in the past decade was the development of high-throughput sequencing. This new technology lets us investigate the epigenome in a global and comprehensive manner, and provides previously unrecognized findings and insights. This review presents an overview of the recent progress in our understanding of epigenetic regulation in type 1 and type 2 diabetes research.
