本研究旨在应用巢式甲基化特异性PCR(nMS-PCR)法检测10种恶性血液系统肿瘤细胞株APC基因启动子的甲基化状态,并探究其在肿瘤发生发展中的作用,同时筛选出APC基因启动子高甲基化的肿瘤细胞株,将其作为研究基因甲基化与表达关系的细胞模型.采用nMS-PCR扩增亚硫酸盐修饰后的10种肿瘤细胞株基因组DNA,检测其APC基因启动子区CpG岛的甲基化状态.结果表明,CA46、U266、Molt4、K562、HL-60、CEM、AKR、U937、Raji细胞的APC基因启动子区均未甲基化,而Jurkat细胞的APC基因启动子区出现甲基化.结论:用nMS-PCR可以准确地检测出恶性血液病细胞株APC基因的甲基化状态,该方法操作简便,可用于检测各种肿瘤细胞基因的甲基化状态.
