Epigenetics of diabetes Type 2 Since Type 2 diabetes is characterized by chronic hyperglycaemia as a result of impaired pancreatic beta cell function and insulin resistance in peripheral tissues, it was thought that the gene might be downregulated in type 2 diabetes patients through DNA methylation. The defects in pancreatic beta cell function and insulin resistance in peripheral tissues were thought to be the result of impaired ATP production from reduced oxidative phosphorylation. It was found that the mRNA expression of PPARGC1A was markedly reduced in pancreatic islets from type 2 diabetic donors compared with that of non-diabetic donors. Using bisulfite testing, it was also
Prevention of diabetes mellitus type 2 causes any change in the risk of diabetes. This is true regardless of if it is caffeinated/decaffeinated; with/without sugar, or potboiled or not. Some studies have shown delayed progression to diabetes in predisposed patients through prophylactic use of metformin, rosiglitazone, or valsartan. Lifestyle interventions are, however, more effective than metformin at preventing diabetes regardless of weight loss. Many other medications are well known to modify risk of diabetes 2 although in most cases they are prescribed for reasons unrelated to diabetes 2. In patients on hydroxychloroquine for rheumatoid arthritis, incidence of diabetes was reduced by 77% though causal mechanisms are
