2、组:TMZ作用于转染PTTGshRNA片段的胶质瘤U251细胞。MTT法检测细胞生长状况,流式细胞仪检测细胞凋亡情况。结果MTT结果显示吸光度值在对照组、TMZ组、PTTGshRNA转染组、PTTGshRNA联合TMz组分别为0.85±0.07、0.58±0.06、0.55+0.07、0.4l±O.05,TMZ组、PTTGshRNA转染组、PTTGshRNA联合TMZ组细胞增殖抑制率分别为(31.56±5.51)%、(35.53±4.60)%、(51.49±6.74)%;PTTGshRNA组及TMZ组
3、与对照组比较差异具有统计学意义(P,o.05),而PTTGshRNA联合TMZ组抑制细胞增殖更明显,与PTTGshRNA组及TMZ组比较差异有统计学意义(P(0.05)。流式细胞仪检测结果显示。48h时对照组凋亡率为(6.29±0.78)%,TMZ组为(33.61±4.88)%。PTTGshRNA组为(39.6l±4.95)%。PTTGshRNA联合TMZ组为(66.23±7.60)%,PTTGshRNA组及TMZ组与对照组比较差异有统计学意义(氏0.05),而PTTGshRNA联合TMZ组的凋亡率较
