摘要 目的:通过siRNA干扰技术研究FUT6基因沉默对Hep G2细胞侵袭和迁移能力的影响。方法:靶向FUT6的siRNA转染肝癌细胞株Hep G2后,通过western blot检测FUT6蛋白的表达,通过流式细胞术检测肝癌细胞表面抗原唾液酸路易斯糖(Sialyl Lewis X,s Le X)表达情况。Transwell小室方法进行细胞迁移和侵袭实验检测肝癌细胞株Hep G2转移和侵袭能力的变化。结果:实验分为3组,分别命名为control(空白对照组),mock(阴性对照scrambled-siRNA)和siRNA-FUT6(实验组)。实验组FUT6蛋白及s Le X抗原较空白对照组明显降低,实验组细胞的迁移能力及侵袭能力下降。结论:siRNA靶向沉默FUT6减少了FUT6蛋白的表达,减少了肿瘤相关抗原s Le X的表达,削弱Hep G2细胞在体外的迁移和侵袭能力,FUT6可能成为肝癌基因治疗的新靶点。
