E3泛素连接酶RNF126调控舌癌细胞侵袭能力的分子机理研究
|
Abstract:
摘要 目的:在人E3泛素连接酶cDNA文库中筛选得到与舌癌发生相关的候选蛋白环指蛋白126(RNF126),利用体外实验进一步分析RNF126调控舌癌发生的分子机制。方法:分子克隆方法构建RNF126克隆和RNAi表达载体,MTT法检测RNF126对人舌癌细胞SCC25增殖的影响,细胞迁移实验分析人舌癌细胞迁移能力受RNF126的影响。结果:与对照组相比,RNF126明显促进SCC25细胞的增殖;抑制RNF126的表达后SCC25细胞的生长明显减缓。单个SCC25细胞形成克隆的能力在抑制RNF126后也受到明显的抑制。Transwell小孔实验证实SCC25细胞迁移能力随着RNF126表达的抑制而降低(P<0.05)。结论:体外实验结果提示RNF126与舌癌的侵袭有一定的关系
