文摘目的:定位survivin基因启动子中参与卡波西肉瘤相关疱疹病毒(Kaposi’s sarcoma-associated herpesvirus,KSHV)复制转录激活因子(replication and transcription activator,RTA)上调survivin表达的重要元件。方法:构建survivin基因启动子的突变报告质粒,采用萤光素酶报告基因检测和染色质免疫共沉淀技术,定位survivin基因启动子区域能与RTA相互作用的顺式元件。结果:突变GC/Sp1和p53两个结合位点启动子活性几乎完全关闭,p53顺式作用元件对RTA上调survivin基因启动子活性具有协同作用。结论:KSHV RTA能够与survivin基因启动子中的GC/Sp1和p53顺式元件相互作用,特异性地增强survivin基因启动子活性。
