摘要
目的 研究托瑞米芬 (TOR)对人肺腺癌细胞系A5 4 9的毒性作用及其与顺铂 (DDP)联用的协同效应 ,探讨肺癌综合治疗的方向。方法 用MTT显色法检测TOR及与DDP联用后对A5 4 9细胞的毒性作用 ,测定其吸光度 (A)值。用流式细胞仪检测细胞DNA含量 ,Westernblot法检测p2 1蛋白表达。结果 TOR能直接抑制A5 4 9细胞的生长 ,≥ 5 μmol L的TOR可明显增强DDP的细胞毒性作用。TOR可加强DDP对S期、G2 期及M期细胞的作用 ,且DDP +TOR后p2 1蛋白表达增加。结论≥ 5 μmol L的TOR与DDP联用对A5 4 9细胞具有显著的协同抗肿瘤效应。
