Insulin induces relaxation and decreases hydrogen peroxide-induced vasoconstriction in human placental vascular bed in a mechanism mediated by calcium-activated potassium channels and L-arginine/nitric oxide pathways.

Insulin induces relaxation in umbilical veins, increasing the expression of human amino acid transporter 1 (hCAT-1) and nitric oxide synthesis (NO) in human umbilical vein endothelial cells (HUVECs). Short-term effects of insulin on vasculature have been reported in healthy subjects and cell culture...
