Effects of hyperglycemia on the AT1 receptor expression and secretory function in an INS-1E beta-cell line

Leung PS , Leung KK , Chu KY

Objectives: We have recently identified an islet renin-angiotensin system in the pancreas which was subjected to upregulation in an obesity-induced mouse model of Type 2 diabetes mellitus (T2DM). Blockade of the AT1 receptor (AT1R) activation in this diabetic model improves islet function. It is well known that hyperglycemia plays a pivotal role in beta-cell dysfunction and T2DM. Nevertheless, glucotoxicity-induced AT1R activation and its consequence in oxidative st...
