Abstract:
Objective To study the effect of angiotensinⅡon the expression of monocyte chemoattractant protein-1 (MCP-1) in cultured human umbilical vein endothelial cells(hUVEC) , and the effect of peroxisome proliferator- activated receptors (PPARs)?and?on MCP-1. Methods MCP-1 protein level was detected by enzyme-linked immunosorbent assay (ELISA) method, and the mRNA expression level of MCP-1 was determined by RT-PCR. Results AngiotensinⅡdistinctly increased the expression of MCP-1 in a dose-dependent manner in cultured hUVECs, and valsartan inhibited the expression of MCP-1 remarkably. Both rosiglitazone (PPAR7 agonist) and fenofibrate (PPAR?agonist) concentration- dependently reduced the expression of MCP-1 in induced by AngⅡ10-6 mol/L. Conclusions AngiotensinⅡcan increase the expression of MCP-1 evidently in hUVECs, which is inhibited by valsartan. The activation of PPARa and PPAR?can decrease the expression of MCP-1 in hUVECs.
