摘要 目的 :探讨顺铂处理人舌癌Tca8113细胞前后细胞增殖活性和凋亡以及人类端粒酶逆转录酶(hTERT)蛋白表达和端粒酶活性的改变 ,进一步揭示顺铂的抗癌机制并初步探讨端粒酶作为化疗敏感性指标的可行性。方法 :以 1/2血药峰值浓度的顺铂处理人舌癌Tca8113细胞 12~ 72h ,应用MTT法检测细胞增殖活性 ,光镜观察细胞凋亡变化特征并计算调亡指数 ,用间接免疫荧光标记法通过流式细胞仪检测hTERT蛋白含量 ,同时行TRAP PCR ELISA端粒酶活性检测。结果 :Tca8113细胞在顺铂作用后 ,细胞增殖活性明显下降 ;出现明显的凋亡 ;hTERT蛋白表达下降的同时端粒酶活性也相应下降 ,而且四者都有一定的时间依赖性。结论 :顺铂可使细胞增殖活性明显下降 ,诱导凋亡产生 ,下调hTERT蛋白表达及抑制端粒酶活性 。
