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
Gestational diabetes repeat OGTT should be carried out 6 weeks after delivery, to confirm the diabetes has disappeared. Afterwards, regular screening for type 2 diabetes is advised. Lifestyle interventions include exercise, diet advice, behavioural interventions, relaxation, self-monitoring glucose, and combined interventions. Women with gestational diabetes who receive lifestyle interventions seem to have less postpartum depression, and were more likely to reach their weight loss targets after giving birth, than women who had no intervention. Their babies are also less likely to be large for their gestational age, and have less percentage of fat when they are born. More research is needed to
