摘要: 目的:探讨p16基因甲基化在急性淋巴细胞白血病(ALL)发生机制中的作用。 方法:采用限制性内切酶酶切结合多聚酶链反应方法检测82例ALL患者白血病细胞p16基因部分启动子和外显子1 CpG岛甲基化的情况。 结果:31例ALL患者存在p16基因的甲基化,1例p16基因纯合缺失;p16存在甲基化与纯合缺失的患者初次化疗完全缓解率和平均生存时间低于p16基因正常表达者。 结论:p16基因甲基化在ALL发生机制中有一定的作用,可作为评估ALL预后的一个指标。

Abstract: Objective To investigate the effects of methylation p16 on pathogenesis of actue lymphoblastic leukemia. Methods The restriction endonuclease enzyme digestion combined with PCR was used to detect p16 gene and methylation in 82 patients with acute lymphoblastic leukemia. Results One homozygous deletion was found in these cases and methylation of p16 gene was found in 38.3% patients (31/81) . Patients without methylation of p16 gene had a higher complete remission rate of first chemotherapy and a longer survival time than those with methylation of p16 gene. Conclusion Methylation of p16 gene probably plays a role in the pathogenesis of acute lymphoblastic leukemia and may have a prognostic value.
