Objective: Endothelial dysfunction is a key event in the onset and progression of atherosclerosis associated with diabetes. Increasing cell apoptosis may lead to endothelial dysfunction and contribute to vascular complications. Therefore, we aimed to elucidate the possible role and mechanism of ibrolipim in preventing endothelial dysfunction induced by high glucose. Methods: Human umbilical vein endothelial cells (HUVECs) were cultured respectively under normal glucose level (5.5 mM), high glucose level (33 mM), and high glucose level with ibro...
