Abstract:Objective To investigate the effect of receptor activator of nuclear factor-κB ligand (RANKL)on the secretion of vascular endothelial growth factor(VEGF)induced by angiotensinⅡ (AngⅡ)in human renal podocytes,and to explore whether AngⅡaffecting VEGF expression in podocytes through RANK/RANKL signaling pathway.Methods The human renal podocytes differentiated into dendrites were selected as research subjects.They were dealt with AngⅡin different concentrations (0,1,10,100 nmol/L).Real-time fluorescence quantitative PCR was performed at different time(0,6,12,24 h)to detect the changes in mRNA expression of the genes VEGF,RANK,and RANKL.Then podocytes were stimulated with different doses of RANKL and 100 nmol/LM AngⅡfor 24 h.The expression of VEGF mRNA was detected by RT-PCR and the apoptosis rate of podocytes was detected by flow cytometry.Results AngⅡinduced podocyte expression of VEGF,RANK,and RANKL in a dose-and time-dependent manner(P<0.05),while excess RANKL showed dose-dependent blockade of VEGF expression increasing (P<0.05).Compared with the control group,AngⅡsignificantly induced podocyte apoptosis(P<0.05),while RANKL inhibited podocyte apoptosis induced by AngⅡ (P<0.05).Conclusion AngⅡmay affect podocyte expression of VEGF through RANK/RANKL signaling pathway.RANKL inhibits the apoptosis of the podocytes induced by AngⅡby regulating the expression of VEGF gene through feedback regulation and protects the kidneys.
