摘要 目的探讨水飞蓟宾对人结肠癌细胞SW480的生长及对侵袭转移的抑制作用。方法将人结肠癌细胞SW480用不同浓度的水飞蓟宾治疗后,采用MTT法检测水飞蓟宾对SW480细胞增殖的抑制作用;流式细胞术检测水飞蓟宾是否能诱导SW480细胞凋亡和周期阻滞;将SW480细胞置于2ng/m L的TGF-β中培养,用transwell技术检测水飞蓟宾是否能抑制SW480细胞的侵袭转移能力;Western blot检测肿瘤侵袭力相关蛋白MMP-9和vimentin的表达。结果水飞蓟宾可显著抑制SW480细胞的增殖并使细胞进入G2/M阻滞;水飞蓟宾可显著抑制SW480细胞TGF-β依赖的侵袭转移效应,并降低MMP-9和vimentin的表达。结论水飞蓟宾抑制人结肠癌细胞SW480生长和侵袭转移。
