摘要 目的检测脑胶质瘤中P33ING1的基因和蛋白表达,探讨其在胶质瘤发生、发展中的作用及临床意义。方法选取行脑胶质瘤手术切除的新鲜胶质瘤标本50例,分别应用RT-PCR方法和S-P免疫组织化学方法检测P33ING1在瘤组织及正常脑组织中的表达。实验数据用SPSS11.5软件包进行统计。结果50例胶质瘤中P33ING1mRNA和蛋白的阳性表达率均为90%(45/50),正常脑组织中全部表达阳性(100%)。P33ING1蛋白表达的LI值与P33ING1mRNA表达的RI值呈显著正相关(r=0.8841,P<0.01)。随着肿瘤级别的升高基因与蛋白水平的表达均随之减少(P<0.01)。结论抑癌基因P33ING1异常表达与其恶性程度密切相关。检测其表达水平的变化对胶质瘤的早期诊断、基因介导治疗及判断预后方面均有重要指导意义。
