Salidroside and FG-4592 ameliorate high glucose-induced glomerular endothelial cells injury via HIF upregulation.

Increasing research indicates that hyperglycemia plays a crucial role in the progression of diabetic nephropathy (DN); however, effective treatment for preventing or slowing DN progression are seriously lacking. Although salidroside (SAL) has been demonstrated to have a positive anti-diabetic effect, the cellular mechanisms remain unclear. FG-4592, a novel prolyl hydroxylase inhibitor, was used to regulate HIF-1α and HIF-2α expression.
