摘要 目的采用RNAi干扰细胞通讯因子Notch-1对肝癌细胞BEL-7402中AFP表达及细胞增殖的影响。方法通过siRNA抑制BEL-7402细胞中Notch-1的表达,采用qRT-PCR和Western blotting法,检测其对AFP表达的影响,采用MTI法测定细胞增殖情况。结果 siRNA抑制Notch-1达后,AFP mRNA及其蛋白水平显著下降,RNAi干扰组与对照组比较BEL-7402细胞生长明显受抑制(P<0.01)。结论 Notch-1 siRNA可以下调肝癌细胞BEL-7402中AFP mRNA及其蛋白的表达水平,抑制BEL-7402细胞的生长,提示Notch-1基因在肝癌细胞的发生、发展中具有重要作用,Notch-1可能是AFP过量表达肝癌的治疗靶点。 【Objective】 To investigate the effects of RNAi-mediated gene silencing of Notch-1 transcriptional factor on the expression of AFP and cell proliferation in hepatocellular carcinoma cells BEL-7402.【Methods】 The mRNA of Notch-1 BEL-7402 hepatocellular carcinoma cells was silenced by siRNA;the expression of AFP mRNA and protein were examined by RT-PCR and Western blot.MTI assay was used to assess the cell growth.【Results】 The expression of AFP in siRNA group was significantly lower than control group in the level of mRNA and protein when the Notch-1 was down-regulated by siRNA,and the proliferation of BEL-7402 cells were significantly inhibited.【Conclusion】 Small interference RNA of Notch-1 can effectively down-regulate AFP expression and inhibit growth of the BEL-7402.which suggest that Notch-1 is a possible therapeutic target for AFP overexpression hepatocellular carcinoma.
