吴茱萸碱联合小檗碱对CCD-18Co诱导的结肠上皮细胞表型转化的调节效应(英文)
发布时间:2021-12-30 02:46
目的基质细胞之间或基质细胞与癌细胞之间存在着细胞转分化过程。吴茱萸碱和小檗碱是中药方剂左金丸的主要药理成分,二者在肿瘤微环境重塑中起着至关重要的作用。本研究旨在探讨吴茱萸碱联合小檗碱(cBerEvo)对肿瘤相关成纤维细胞诱导的结肠上皮细胞表型转化的影响及其相关机制。方法采用制备好的人结肠肌成纤维细胞系CCD-18Co条件化培养基诱导正常人结肠上皮细胞系HCoEpiCs向间质细胞转化,同时观察TGF-β受体抑制剂LY364947或cBerEvo对HCoEpiCs细胞转化是否有抑制作用。用相差显微镜观察HCoEpiCs形态学变化。免疫荧光显微镜观察及检测上皮细胞-间充质转化标记物包括E-钙粘蛋白(E-cadherin),波形蛋白(vimentin)以及α-平滑肌肌动蛋白(α-SMA)的表达。创伤愈合试验评估细胞迁移情况。Western blotting检测E-cadherin、vimentin、α-SMA、Snail、ZEB1及Smads蛋白表达。结果与对照组细胞相比,经肿瘤相关成纤维细胞样CCD-18Co细胞诱导的HCoEpiCs细胞表达E-cadherin下调、表达vimentin、α...
