Abstract： 目的:研究HGF对肝细胞癌SMMC-7721的上皮-间叶转化的作用,并对其机制进行探讨.方法:HGF处理SMMC-7721后,应用细胞培养、Transwell、划痕实验、WB技术研究HGF对肝癌细胞SMMC-7721上皮-间叶转化的作用.并应用P13 kinase抑制物LY294002 10umol/L顸处理细胞,观察SMMC-7721的变化,研究P13 kinase对于HGF作用机制的影响.结果:Transwell和划痕实验显示HGF处理的细胞侵袭和转移能力增强,蛋白印迹结果显示HGF处理的细胞的N-cad、MMP-2、MMP-9和Vimentin的表达增加,E-cad的表达减少.LY294002预处理后,细胞不再受HGF的影响,细胞的形态没有明显变化.Transwell和划痕实验结果与未经处理的SMMC-7721相同.蛋白印迹结果显示:细胞的N-cad、MMP.2、MMP-9、Vimacntin和E-cad的表达变化不明显.结论:HGF能够促进SMMC-7721的上皮间叶转化,这种作用通过PD Kinase实现.
