| 摘 要： | 目的: 观察HPV16 E6 siRNA表达载体对宫颈癌Caski细胞凋亡和增殖的影响.方法: 利用脂质体将HPV16 E6特异性siRNA表达载体转染Caski细胞,通过荧光定量RT-PCR检测E6 mRNA的变化,流式细胞仪检测E6蛋白和细胞凋亡率的变化,MTT法和细胞克隆法检测细胞增殖的变化.结果: HPV16 E6 siRNA表达载体可明显抑制Caski细胞E6 mRNA和E6蛋白的表达,抑制率分别为89.5%和98.1%;表达载体可明显增加细胞凋亡率,抑制细胞的增殖和克隆的形成.结论: HPV16 E6 siRNA表达载体可以特异高效地抑制宫颈癌Caski细胞E6基因的表达,增加细胞的凋亡,抑制肿瘤细胞增殖和克隆的形成.
