摘要
目的 :探讨人参单体皂甙Rh2 与顺铂 (DDP)联合应用对前列腺癌细胞株PC - 3M细胞凋亡的影响。方法 :应用MTT实验检测细胞生长抑制率 ,NP - 4 0快速分离片段化DNA电泳、流式细胞计量术观察PC - 3M细胞凋亡的变化。结果 :15 0mg/LRh2 与 0 4mg/LDDP联合给药 :①可使 0 4mg/LDDP的肿瘤细胞生长抑制率由2 5 0 %提高到 6 1 0 % ,增加了 1 4 4倍 ;②凋亡片段化DNA电泳检测显示较二者单独给药时更明显的DNA凋亡梯形电泳带 ;③可使 0 4mg/LDDP诱导PC - 3M细胞凋亡率从 0 3%提高到 5 2 2 % ,相当于其 10倍剂量 4 0mg/LDDP的诱导凋亡效应 ( 5 7 4 % ) ,明显高于Rh2 单独应用的凋亡率 13 6 % (P <0 0 1)。结论 :Rh2 能显著增强DDP对PC
AIM: To study the inducing apoptotic effect of Cisplatin (DDP) combined with Ginsenoside Rh 2 on PC-3M prostatic cancer cells in vitro. METHODS: Cell viability was examined by MTT test and the apoptosis of PC-3M by electrophoresis of NP-40 extracting fragmental DNA and flowcytometry. RESULTS: Pc-3M cells were exposed to 15.0 mg/L Rh 2 combined with 0.4 mg/L DDP: ①Cell viabililty inhibitory rate was increased by 1.44 times from 25.0% (with 0.4 mg/L DDP) to 61.03%. ②Characteristic apoptotic DNA laddering was found more obviously than using either agent alone. ③Apoptotic rate of PC-3M was increased from 0.32% (with 0.4 mg/L DDP) to 52.2%, which showed similar effect with 4.0 mg/L DDP, it was much higher than that of 15.0 mg/L Rh 2 alone (13.6%) ( P<0.01 ).CONCLUSION: Rh 2 greatly enhances the apoptotic effect of DDP on PC-3M prostatic cancer cells.
