miR-210对肾透明细胞癌血管生成的影响
Effect of miR-210 on angiogenesis of renal clear cell carcinoma
摘要
Abstract
Objective To investigate the effect of miR-210 on angiogenesis of human renal clear cell carcinoma . Methods Detect the expression of miR-210 in 40 cases of renal clear cell carcinoma tissues , and analyze the rela-tionship between the expression of miR-210 and microvessel density ( MVD) .miR-210-ASO was lipotransfected in-to renal clear cell carcinoma cell line 786-O.RT-qPCR was used to verify the transfection effect .The effect of the supernatant of control group , negative control group and miR-210-ASO group tumor cells on the lumen formation of human umbilical vein endothelial cells ( HUVEC) was observed in a 3-D culturesystems .The transplantation tumor model of nude mice was established , and the effect of miR-210 on the formation of the transplanted tumor micro vessel was observed by endomucin and VEGF immunofluorescence staining under laser scanning confocal micro -scope.Results The expression of miR-210 was positively correlated with microvessel density in renal clear cell carcinoma ( P<0.05 ) .The expression of miR-210 was significantly decreased in 786-O cells transfected with miR-210-ASO( P<0.05 ) .The lumen formation of HUVEC cells co cultured with miR-210-ASO group cell supernatant was significantly less than that of control group and negative control group ( P<0.05 ) .The tumor volume of miR-210-ASO group was less than that of the control group , and the number of the micro vessel and the VEGF expres-sion were significantly less than that of the control group ( P<0.05 ) .Conclusions Inhibition of miR-210 can suppress blood vessel formation in renal clear cell carcinoma .关键词
