摘要(Abstract):
目的探讨多发性骨髓瘤p16基因甲基化与其预后之间的相关性。方法采用甲基化敏感的限制性内切酶联合聚合酶链反应方法(REP法),检测52名多发性骨髓瘤(MM)患者骨髓细胞p16基因第1外显子的甲基化状态,并检测存在p16基因第1外显子甲基化的MM患者p16基因的mRNA转录水平。对这52名患者的临床资料及预后因素进行分析。结果52名MM患者中,p16基因启动子区第1外显子甲基化率为53.84%(28/52)。存在p16基因第1外显子甲基化的MM患者中,p16基因mRNA阴性率为75%。p16基因甲基化患者的预后不良因素明显高于非甲基化患者。结论多发性骨髓瘤p16基因甲基化与其预后有关。
