Abstract:

目的:研究氯硝柳胺对人结肠癌SW480细胞生长、周期及凋亡的影响,并探讨其可能的机制。方法:CCK-8法检测氯硝柳胺对SW480细胞生长的抑制作用,流式细胞术检测氯硝柳胺对SW480细胞周期及凋亡的影响,Western Blot法检测氯硝柳胺对SW480细胞蛋白水平的调控。结果:氯硝柳胺对SW480细胞生长有显著抑制作用,其半抑制浓度为4.6μmol/L。与对照组相比,实验组SW480细胞G0/G1期比例增加,S期细胞比例减少,凋亡率增加(P<0.05)。实验组β-Catenin蛋白的表达较对照组下调(P<0.05),Cyclin D1表达无显著差异(P>0.05)。结论:氯硝柳胺可抑制结肠癌SW480细胞的生长,将其阻滞在G0/G1期,促进细胞凋亡,抑制Wnt/β-Catenin通路,是一个具有潜力的抗结肠癌药物
