Epigenetics of diabetes Type 2 have shown that miRNAs have pivotal roles in many different gene regulatory pathways. A subset of miRNAs has been shown to be involved in metabolic regulation of glucose homeostasis and in epigenetics of diabetes type 2. Pancreatic islet-specific miR-375 inhibits insulin secretion in mouse pancreatic β-cells by inhibiting the expression of the protein myotrophin. An overexpression of miR-375 can completely suppress glucose-induced insulin secretion, while inhibition of native miR-375 will increase insulin secretion. In another study, increasing the level of miR-9, a different miRNA, resulted in a severe defect in glucose-stimulated insulin release. This happens because miR-9 down-regulated the transcription
Epigenetics of diabetes Type 2 was seen in an experiment when a high glucose treatment of cultured monocytes increased recruitment of the HATs CREB-binding protein (CPB) and PCAF, leading to increased histone lysine acetylation at the cyclooxygenase-2 (COX-2) and TNF-inflammatory gene promoters. This led to a corresponding increase in gene expression, which was similar to the increased histone lysine acetylation at these gene promoters in type 1 diabetes and type 2 diabetes patients compared to healthy control volunteers. There are several factors that put people at higher risk of contracting Type 2 diabetes. Among these are obesity, lack of exercise, and aging. But, not everyone
