摘要 目的探讨急性髓系白血病(AML)、急性淋巴细胞白血病(ALL)患者骨髓肾母细胞癌基因(WT1)表达水平和患者不同类别核型异常之间的关系。方法用实时荧光定量聚合酶链反应(RT-PCR)检测136例初发急性白血病患者(AML 108例和ALL 28例)骨髓WT1基因表达水平,并用染色体分析、多重RT-PCR和荧光原位杂交技术(FISH)检测确定患者有无核型异常。结果核型正常组骨髓WT1基因表达水平为6.02(2.01,16.11),核型异常组为12.13(3.61,28.98),对照组为0.22(0.11,0.55),核型正常组、核型异常组WT1表达水平高于对照组(χ~2=31.847,P=0.000);核型异常组WT1表达水平和核型正常组差异有统计学意义(Z=-2.074,P=0.038)。在不同类别的核型异常中,三体8组、BCR-ABL组、AML1-ETO组、PML-RARa组、MLL基因重排组、CBFβ-MYH11、TEL基因重排组、复杂核型组和E2A-PBX1组,WT1的表达水平分别为12.00(5.50,17.11)、10.30(0.70,10.99)、2.50(1.60,8.00)、29.98(18.96,36.00)、14.50(10.75,33.25)、19.00(8.65,47.00)、20.00(3.00,20.00)、38.11(10.95,77.50)和0.03(0.01,0.31)。各组WT1基因表达水平差异有统计学意义(χ~2=38.787,P=0.000),E2A-PBX1组WT1表达水平低于其他核型组;E2A-PBX1组与对照组比较,WT1表达水平差异无统计学意义(Z=-1.402,P=0.185)。结论 WT1表达水平与患者核型异常类别有一定的联系,不同类别核型异常患者中WT1基因表达水平差异较大。
