目的:探讨Caveolin-1对肝癌细胞ST6Gal-I表达的影响及与肿瘤粘附行为的关系.材料和方法:利用Rea-time PCR和Westem-blot等方法检测Caveolin-1在小鼠肝癌细胞系(Hca-F,Hepa1-6等)中的表达情况;利用RNAi方法下调Caveolin-1在Hca-F细胞中的表达;利用Rea-time PCR等方法分析Caveolin-1表达下调对Hca-F细胞ST6Gal-I及细胞表面α2,6连接唾液酸的影响;利用Western-blot方法分析Caveolin-1表达下调对FAK介导的粘附信号传导通路的影响;利用细胞粘附实验分析Caveolin-1表达下调对Hca-F细胞粘附能力的影响;在下调Caveolin-1表达的Hca-F细胞重新表达Caveolin-1和ST6Gal-I,然后观察细胞粘附的变化情况.
