红景天苷促进人血管内皮细胞系EA.hy926增殖与迁移
Salidroside promotes proliferation and migration of human vascular endothelial cell line EA.hy926
摘要
Abstract
Objective To investigate the effect of salidroside(SAL)on the proliferation and migration of human vascular endothelial cell line EA.hy926.Methods The cells were divided into control group and test groups of 1,10 and 100 nmol/L SAL,10 nmol/L SAL+2 μg/mL avastin(vascular endothelial growth factor(VEGF)blocker)group,10 nmol/L SAL+2 μg/mL IgG(blocker negative control)group,10 nmol/L SAL+8 μg/mL avastin group,10 nmol/L SAL+8 μg/mL IgG group,10 μmol/L YC-1[hypoxia inducible factor-1α(HIF-1α)blocker]group and 10 μmol/L YC-1+10 nmol/L SAL group.The proliferation and migration of EA.hy926 cells were detected by MTS assay and Transwell cell migration experiments.RT-qPCR and Western blot were used to measure the gene and protein level of HIF-1α and VEGF.The luciferase report gene experiment was used to find the effect of SAL on HIF-1α transcription activity of EA.hy926 cells.The guanylate cyclase activator(YC-1)was used as a HIF-1α blocker to verify potential effect of SAL on the expression of VEGF through HIF-1α.Results SAL significantly promoted proliferation of EA.hy926 cells(P＜0.05)and the proliferation promoting effect of SAL(10 nmol/L)was significantly reduced by the VEGF blocker bevacizumab avastin(2 μg/mL)(P＜0.05).SAL significantly promoted migration of EA.hy926 cells(P＜0.05),and this effect was significantly inhibited by avastin(8 μg/mL)(P＜0.05).SAL increased the expression of HIF-1α and VEGF gene and protein,and promoted the transcription of HIF-1α(P＜0.05).The level of HIF-1α and VEGF protein decreased by YC-1,a HIF-1α bloc-ker(P＜0.05).Conclusions HIF-1α/VEGF pathway is potentially involved in SAL promoted proliferation and migration of EA.hy926 cells.关键词
