摘要 目的探讨Autotaxin(ATX)mRNA在人脑胶质瘤中的表达及与人脑胶质瘤临床病理特征之间的关系。方法收集临床切除的正常脑组织及经病理证实的各级胶质瘤组织23例,以WHO分级对其进行分组,Ⅰ~Ⅱ为良性组、Ⅲ~Ⅳ级为恶性组,其中良性胶质瘤8例,恶性胶质瘤15例。另收集正常脑组织5例,应用逆转录聚合酶链反应(RT-PCR)、免疫组织化学染色方法研究各组中ATX mRNA及蛋白的表达。结果 ATXmRNA在恶性脑胶质瘤表达为1.237±0.141,良性胶质瘤为1.396±0.142,均明显高于正常脑组织(1.019±0.241),有显著性差异(P<0.05),但良、恶性胶质瘤中ATX mRNA表达无明显差异。ATX蛋白在恶性脑胶质瘤表达为0.702±0.189,良性胶质瘤为0.538±0.148,均明显高于正常脑组织(0.116±0.062 5),有显著性差异(P<0.05),但良、恶性胶质瘤中ATX蛋白表达无明显差异。结论人脑胶质瘤中ATX在核酸与蛋白水平均有表达,ATX基因过表达可能与人脑胶质瘤的发生发展密切相关。
