1、主鲨垦蓥查!2月第35卷第2期ChinJUrol,February2014,Vo1.35,No2147·基础研究·替西罗莫司与顺铂联合应用对膀胱癌增殖的影响陈业刚王建民杨拓刘晓强孙光【摘要】目的分析替西罗莫司(CCI一779)与顺铂(DDP)联合应用对膀胱癌增殖的影响,探讨其协同作用机制。方法2011年3—10月,采用噻唑蓝法检测CCI.779、DDP及CCI.779联合DDP对膀胱癌T24细胞生长的抑制作用,蛋白质印迹法检测T24细胞p-mTOR、p-p70S6K、p21蛋白的表达;制作小鼠膀胱癌皮下移植瘤动物模型,险测CCI一779、D
2、DP及CCI.779联合DDP对移植瘤的抑制作用,TUNEL法检测移植瘤细胞凋亡,免疫组化检测Ki一67蛋白的表达。结果在体外实验中,CCI-779、DDP单用能够抑制膀胱癌T24细胞的增殖,呈时间和浓度依赖性,两者联合应用能够明显增加对T24细胞的抑制作用;75nmol/L浓度时,CCI一779及DDP对T24细胞的抑制率分别为37.0l%、38.89%,而二者联合应用抑制率为85.56%,具有明显的协同作用;p-mTOR、p-p70S6K、p21蛋白的表达在CCI一779及CCI一779与DDP联合治疗组中明显低于DDP单独治疗组及空白
