摘    要:目的探讨p73基因甲基化在急性淋巴细胞白血病(ALL)发病机制中的作用。方法对吉林大学第二医院2001~2004年42例ALL患者采用限制性内切酶结合多聚酶链反应方法(REP)检测p73基因第一外显子甲基化情况。结果42例ALL患者甲基化检测结果28.6%(12/42),存在p73甲基化患者化疗前周围血白细胞数及骨髓原始细胞数均高于无p73甲基化患者,而且首次化疗即获完全缓解及平均缓解时间较无甲基化者差异有显著性。结论p73基因甲基化在ALL发病机制中有一定的作用。其检测对估计预后具有临床意义。

关 键 词:p73  基因  白血病  淋巴细胞  甲基化

Abstract:Objective To investigate the effects of methylation of p73 gene on pathogenesis of acute lymphoblastic leukemia.Methods The restriction endonuclease enzyme digestion combined with PCR was used to detect p73 gene and methylation in 42 patients with acute lymphoblastic leukemia.Results Methylation of p73 gene was found in 28.6%(12/42).Patients without methylation of p73 gene had a higher complete remission rate of first chemotherapy and a longer survival time than those with methylation of p73 gene.Conclusion Methylation of p73 gene probably plays a role in the pathogenesis of acute lymphoblastic leukemia and may have clinical significance in predicting prognosis of ALL.
Keywords:Gene p73 Leukemia Lymphocyte Methylation
