摘要 目的 探讨重组慢病毒BAMBI-shRNA对结肠癌细胞体外侵袭转移能力的影响.方法 设计并合成慢病毒shRNA-BAMBI载体,转染入体外培养的人结肠癌细胞株HCT-116,转染分组:空白对照组(A组)、阴性对照组(B组)和实验组(C组);采用Western blot检测转染后HCT-116细胞中BAMBI蛋白表达水平;采用Transwell实验分析慢病毒shRNA-BAMBI载体对HCT-116细胞体外迁移力和侵袭力的影响.结果 C组BAMBI蛋白的表达强度弱于A组和B组(P<0.05),而A组与B组比较,BAMBI蛋白表达水平则无统计学差异(t=1.629,P>0.05).细胞迁移和侵袭实验中,转染作用24 h后,C组迁移穿膜细胞数和侵袭穿膜细胞数均明显减少,明显低于其余两组(P<0.05),而A组和B组之间比较无统计学差异(P> 0.05).结论 BAMBI-shRNA慢病毒能通过沉默HCT-116细胞中BAMBI蛋白的表达,降低HCT-116细胞的侵袭和迁移能力.
