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
Diabetes mellitus type 2 associated with youth and type 2 with being overweight. The term "mellitus" or "from honey" was added by the Briton John Rolle in the late 1700s to separate the condition from diabetes insipidus which is also associated with frequent urination. Effective treatment was not developed until the early part of the 20th century when the Canadians Frederick Banting and Charles Best discovered insulin in 1921 and 1922. This was followed by the development of the long acting NPH insulin in the 1940s. Diabetes mellitus type 2 Diabetes mellitus type 2 (also known as type 2 diabetes) is a long-term metabolic
