摘要: [摘要]〓
〖HTH〗目的〖HTSS〗〖KG*2〗探讨神经元表达下调基因9(neural precursor cell expressed developmentally downregulated,NEDD9)在人脑胶质瘤组织中的表达情况。
〖HTH〗方法〖HTSS〗〖KG*2〗采集人脑胶质瘤术中切除组织标本36例作为试验组(低级别胶质瘤组14例,高级别胶质瘤组22例),重型颅脑损伤内减压切除的正常脑组织10例作为对照组。采用逆转录聚合酶链反应法测定NEDD9 mRNA的转录水平,同时采用免疫组织化学SP法检测人脑胶质瘤组织中NEDD9蛋白的表达情况。
〖HTH〗结果〖HTSS〗〖KG*2〗NEDD9蛋白阳性表达率在正常脑组织、低级别胶质瘤、高级别胶质瘤中呈明显上升趋势,低级别胶质瘤组和高级别胶质瘤组NEDD9蛋白阳性表达率明显高于对照组(P<005)。低级别胶质瘤组和高级别胶质瘤组NEDD9 mRNA表达量明显高于对照组,高级别胶质瘤组NEDD9 mRNA表达量明显高于低级别胶质瘤组(P<005)。
〖HTH〗结论〖HTSS〗〖KG*2〗NEDD9在神经胶质瘤中的转录和蛋白表达水平显著增高,且表达率及表达水平随肿瘤恶性程度的加重而增高。

Abstract: [Abstract]〓Objective〖HTSS〗〓To explore the expression and significance of  neural precursor cell expressed developmentally downregulated 9(NEDD9) in human glioma.
〖HTH〗〖WTHZ〗Methods〖HTSS〗〓The expression of NEDD9 protein was detected by SP immunohistochemistry and its mRNA was examined by reverse transcription polymerase chain reaction in 36 human gliomas specimens and 10 brain trauma with intracranial decompression, respectively. 
〖HTH〗〖WTHZ〗Results〖HTSS〗〓The positive expression rate of NEDD9 protein was increased in normal brain tissue, low grade glioma and high grade glioma. The positive rate of NEDD9 protein expression in low grade glioma group and high grade glioma group was significantly higher than that of control group(P<005). The expression of NEDD9 mRNA in the low grade glioma group and the high grade glioma group was significantly higher than that in the control group. The expression of NEDD9 mRNA in the high grade glioma group was significantly higher than that of the low grade glioma group(P<005).
〖HTH〗〖WTHZ〗Conclusion〖HTSS〗〓The expression of NEDD9 protein and the level of mRNA transcription were increased significantly in gliomas. Detecting NEDD9 protein or mRNA in human glioma can be used for judging the malignancy degree.
