摘要: 目的探讨针对肝细胞生长因子(HGF)受体c-Met的RNA干扰对人晶状体上皮细胞增殖的影响。方法构建针对人c-Met基因的小干扰RNA(siRNA),转染体外培养的人晶状体上皮细胞,利用实时荧光定量聚合酶链反应(Real-TimePCR)检测细胞中c-Met mRNA的表达变化,应用MTT法检测HGF诱导后人晶状体上皮细胞增殖。结果与对照组相比,转染后的人晶状体上皮细胞中c-Met mRNA表达水平明显下降(P<0.01);与单纯HGF诱导组相比,转染后HGF诱导的人晶状体上皮细胞生长明显减慢,增殖能力明显下降(P<0.01)。结论针对人c-Met基因的RNA干扰可以有效阻断人晶状体上皮细胞中c-Met mRNA的表达,并能抑制HGF诱导的人晶状体上皮细胞的增殖。

Abstract: Objective To observe the effect of small-interfering RNA(siRNA) targeting c-Met,the receptor of hepatocyte growth factor(HGF),on the proliferation of human lens epithelial cells(LECs).Methods siRNA was transferred into LECs cultured in vitro by HiperFect Transfection Reagent.Real-Time PCR was applied to observe the expression of c-Met mRNA in LECs after gene transfer,and MTT assay was used to detect the proliferation of LECs induced by HGF.Results The expression of c-Met mRNA in LECs was significantly decreased in the experimental group,compared to that in the controls(P<0.01).Proliferation of LECs induced by HGF was inhibited,compared with the single HGF stimulated group(P<0.01).Conclusion The RNA interference targeting c-Met can effectively inhibit the expression of c-Met mRNA,and the proliferation of LECs induced by HGF.
