摘要 死亡相关蛋白激酶(Death—associatedproteinkinase,DAPK)是一种相对分子质量为160×10^3、钙调蛋白依赖的丝氨酸/苏氨酸蛋白激酶。DAPK是一种正性细胞凋亡调节因子,通过多种途径诱导肿瘤细胞凋亡。通过动物实验发现DAPK在肿瘤发育的早期阶段抑制细胞转化,并且能抑制晚期肿瘤转移。近年来的临床研究结果表明DAPK基因启动子异常甲基化与消化道、泌尿道、头颈部、呼吸道肿瘤的发生发展密切相关。此外,对造血系统肿瘤的研究揭示伯基特淋巴瘤、滤泡性淋巴瘤、弥漫大B细胞淋巴瘤、急性髓系白血病(AML)、骨髓增生异常综合征(MDS)、慢性淋巴细胞自血病、多发性骨髓瘤同样存在着较高频率的DAPK基因启动子甲基化。我们应用甲基化特异性PCR(Methylation—specificPCR,MSP)对MDS患者DAPK基因启动子甲基化状况进行了检测。
