摘要 目的 探讨IWR-1对人肝癌细胞株Hep3B细胞增殖的影响及可能的机制。方法 用不同浓度IWR-1(2、4、8、16μmol/L)处理Hep3B细胞,CCK-8法检测细胞生长抑制率;流式细胞仪检测细胞周期变化及细胞凋亡率;Western blot法检测细胞中蛋白表达的变化,实时定量RT-PCR检测β-catenin和c-myc mRNA表达的变化。结果 IWR-1对人肝癌Hep3B细胞的生长抑制作用呈现剂量和时间依赖性(P<0.01)。流式细胞术结果显示,Hep3B细胞的细胞周期呈现明显的G0/G1期阻滞,且细胞凋亡率明显升高(P<0.01),呈现剂量依赖性。IWR-1可引起β-catenin和c-myc mRNA表达下降,β-catenin、c-myc蛋白表达下降,而Axin 1和p-β-catenin蛋白表达上升。结论 IWR-1可以抑制人肝癌细胞株Hep3B的增殖,其机制可能是通过抑制Wnt/β-catenin通路来实现
