摘要
目的基于上皮-间质细胞转换(EMT)途径探索槲皮素抑制非小细胞肺癌细胞系H3122细胞侵袭迁移的分子机制。方法 MTT法检测细胞增殖情况; Transwell小室侵袭迁移实验检测H3122细胞侵袭迁移情况; ELISA实验检测H3122细胞分泌EGF和HGF能力变化; qPCR检测H3122细胞Snail1、E-cadherin表达情况; Western bloting检测对H3122细胞Fibronactin、Vimentin、ZO-1蛋白含量的影响。结果槲皮素可抑制H3122细胞的增殖,具有时间-浓度依赖性,并可显著抑制H3122细胞的侵袭迁移(P <0. 05),对H3122细胞分泌EGF、HGF的能力具有显著的抑制作用(P <0. 05),槲皮素可显著降低H3122细胞Snail1 mRNA表达以及H3122细胞Fibronactin、Vimentin蛋白含量,增加E-cadherin mRNA、ZO-1蛋白含量。结论槲皮素具有抑制H3122细胞增殖、迁移的作用,并可抑制H3122细胞分泌EGF、HGF以及表达Snail转录因子的能力,提高E-cadherin mRNA表达,降低Fibronectin、Vimentin两种蛋白的表达,促进ZO-1分子蛋白的表达,以此抑制H3122细胞迁移。
