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
The Environmental Determinants of Diabetes in the Young The Environmental Determinants of Diabetes in the Young The Environmental Determinants of Diabetes in the Young is a longitudinal study examining the environmental causes of Type 1 diabetes(T1D), formerly known as juvenile diabetes. The study follows children at high genetic risk for T1D from birth to 15 years of age. Although genetic markers for Type 1 Diabetes have been identified, genetic predisposition is not the only factor in development of the disease. An increasing body of evidence, including rising rates of T1D diagnosis and incomplete penetrance of the disease in genetically predisposed individuals, suggests that environment may play an equally
