摘要
目的研究和厚朴酚(honokiol,HNK)对肝癌细胞Hep3B的迁移、转移能力的影响并探讨可能机制。方法采用细胞划痕实验、transwell迁移实验检测不同浓度HNK刺激24 h后Hep3B细胞迁移能力的改变。经裸鼠尾静脉注射Hep3B细胞建立人肝癌细胞肺转移瘤模型,观察HNK对肝癌细胞转移成瘤能力的影响。最后采用Western blot法检测不同浓度HNK刺激下PI3K/AKT通路及上皮-间充质转化(epithelial-to-mesenchymal transition,EMT)相关蛋白水平以进一步探索HNK抑制肝癌细胞迁移、转移能力的可能机制。结果细胞划痕实验、transwell迁移实验均证实经HNK刺激后Hep3B细胞迁移能力下降且呈浓度依赖性(P <0.05)。体内肺转移瘤模型中,HNK治疗组肺部转移瘤数目较对照组减少(P <0.05)。HNK刺激后,Hep3B细胞中p-PI3K、p-AKT、波形蛋白(Vimentin)、神经-钙依赖性粘附素(N-cadherin)蛋白表达降低(P <0.05),上皮-钙依赖性粘附素(E-cadherin)蛋白升高(P <0.05)。结论 HNK通过抑制PI3K/AKT通路逆转EMT,从而影响Hep3B细胞迁移和转移。
