文摘目的探讨热休克蛋白70(HSP70)在膀胱癌细胞株EJ中的热诱导表达及其意义。方法 106/ml EJ置于1.5 ml Eppendorf管中,将它们在不同温度水浴分别加热诱导2 h、4 h、6 h、8 h。5%CO2孵箱中(37℃)恢复2 h。流式细胞术(FCM)和蛋白印迹法检测HSP70,反转录-聚合酶链反应(RT-PCR)检测HSP70 m RNA,SPSS16.0统计软件处理数据。结果人膀胱癌细胞株EJ中HSP70随着温度的增高表达增多,差异有统计学意义(P<0.05),但温度超过43℃时,细胞死亡率增高;随着热诱导时间的延长而增多,差异有统计学意义(P<0.05),超过8 h EJ中HSP70不再增高。结论人膀胱癌细胞株EJ中HSP70热诱导表达的最适条件是43℃、6 h,这对基于HSP70膀胱肿瘤的瘤苗制作提供一定的实验基础。
