摘要 目的观察沉默G250基因对肾癌786-0细胞体内增殖的影响。方法构建靶向G250的siRNA表达质粒pshRNA-G250并转染肾癌786-0细胞,12只BALB/c裸鼠分为阴性对照组和干扰成瘤组,干扰成瘤组每只裸鼠皮下接种5×106个G250基因沉默后的肾癌786-0细胞(786-0/si-G250-b),以转染空质粒的细胞(786-0/si-G250-0)为对照。观察裸鼠成瘤时间、成瘤率、肿瘤体积变化、绘制生长曲线。成瘤3周后,处死裸鼠,称重瘤块,计算抑瘤率。结果 5×106个细胞皮下接种BALB/c裸鼠均成瘤,实验和对照组肿瘤出现时间分别为(11±1.5)、(15±2.4)d(t=3.381,P=0.007)。7个不同时间点肿瘤的生长体积具有统计学意义(F=84.836,P=0.000)。成瘤3 w后,肿瘤重量分别为(22.224±5.145)mg、(37.353±9.332)mg,(t=3.475,P=0.006),干扰组肿瘤成瘤抑制率为40.50%。结论 G250基因表达沉默抑制了肾癌细胞的体内增殖能力。
