Potent Vasoconstrictor Kisspeptin-10 Induces Atherosclerotic Plaque Progression and Instability: Reversal by its Receptor GPR54 Antagonist.

ABSTRACT: Kisspeptin-10 (KP-10), a potent vasoconstrictor and inhibitor of angiogenesis, and its receptor, GPR54, have currently received much attention in relation to pre-eclampsia. However, it still remains unknown whether KP-10 could affect atherogenesis. We evaluated the effects of KP-10 on human umbilical vein endothelial cells, human monocyte-derived macrophages, human aortic smooth muscle cells in vitro, and atherosclerotic lesions in apolipoprotein E-deficient (ApoE-/-) mice in vivo. KP-10 significantly increased the adhesion of human monocytes to human umbilical vein endothelial cells, which was significantly inhibited by pretreatment with P234, a GPR54 antagonist. KP-10 stimulated mRNA expression of tumor necrosis factor-α, interleukin-6, monocyte chemotactic protein-1, intercellular adhes
