Research Abstract

High density lipoprotein (HDL) stimulated AMP kinase (AMPK) in human umbilical vein endothelial cells (HUVECs). HDL activated AMPK through independent two pathways. HDL-induced AMPK activation was mediated by sphingosine-1 phosphate (S1P)/S1P receptor pathway and scavenger receptor (SR-BI)/PDZK-1. S1P/S1P receptor pathway was mediated by calmodulin. SR-BI/PDZK-1 pathway was mediated by calmodulin and LKB1 in HUVECs. Simvastatin, fenofibrate, metrformin and AICAR enhanced protein expression of SR-BI and endothelial nitric oxide synthase (eNOS) in HUVECs. Simultaneous pretreatment of simvastatin and fenofibrate enhanced HDL-induced AMPK/Akt activation in HUVECs.
