AB - Stimulation of Cell Surface F -ATPase Activity by Apolipoprotein A-I Inhibits Endothelial Cell Apoptosis and Promotes Proliferation Claudia Radojkovic, Annelise Genoux, Ve´ronique Pons, Guillaume Combes, Hugo de Jonge, Eric Champagne, Corinne Rolland, Bertrand Perret, Xavier Collet, Franc¸ois Terce´, Laurent O. Martinez Objectives—Several findings argue for a protective effect of high-density lipoproteins (HDLs) against endothelial dysfunction. The molecular mechanisms underlying this protective effect are not fully understood, although recent works suggest that the actions of HDL on the endothelium are initiated by multiple interactions between HDLs (lipid or protein moiety) and cell surface receptors. We previously showed that the mitochondrial related F -ATPase is a cell surface receptor for HDLs and their main atheroprotective apolipoprotein (apoA-I). Herein we test the hypothesis that the cell surface F -ATPase may contribute to the ability of apoA-I and HDLs to maintain endothelial cell survival. Methods and Results—Cell imaging and binding assays confirmed the presence of the F -ATPase at the surface of human umbilical vein endothelial cells (HUVECs) and its ability to bind apoA-I. Cell surface F -ATPase activity (ATP hydrolysis into ADP) was stimulated by apoA-I and was inhibited by its specific inhibitor IF -H49K. Furthermore the antiapoptotic and proliferative effects of
