摘要
目的探讨Notch1信号通路对体外培养的胃癌细胞(BGC-823)增殖的影响,为胃癌的治疗提供新思路。方法将体外培养的胃癌细胞株BGC-823分为三组,空白组加入PBS缓冲液,激活剂组加入Notch1通路激活剂rh-NF-κB,抑制剂组加入Notch1通路抑制剂γ-secretase inhibitorⅡ。Western blot法检测各组Notch-1和Hes-1蛋白表达;MTT法检测细胞增殖情况;流式细胞仪检测细胞周期分布。结果与空白组比较,激活剂组Notch-1和Hes-1呈高表达、抑制剂组呈低表达;激活剂组细胞增殖减低,抑制剂组增殖旺盛;激活剂组S期胃癌细胞所占比例低,抑制剂组所占比例高。P均<0.05。结论 Notch1信号通路激活能抑制胃癌细胞增殖。
