目的 研究GOLPH3在胶质瘤组织中的表达及其临床意义.方法 选取山东大学齐鲁医院和聊城市脑科医院神经外科自2008年7月至2009年12月间手术切除并经病理证实的人脑胶质瘤标本76例,其中Ⅰ级13例,Ⅱ27级例,Ⅲ级25例,胶质母细胞瘤11例.另取9例因脑创伤行内减压术患者的正常脑组织标本作为对照.应用RT-PCR、Western blotting分别检测各标本中GOLPH3 mRNA和GOLPH3蛋白的表达.结果 RT-PCR与Western blotting检测结果显示正常脑组织中GOLPH3 mRNA和GOLPH3蛋白不表达,不同级别胶质瘤组织GOLPH3 mRNA、GOLPH3蛋白的阳性表达率差异无统计学意义（P＞0.05）,而其表达值差异有统计学意义（P＜0.05）,且随着肿瘤病理级别的增高,胶质瘤组织中GOLPH3mRNA、GOLPH3蛋白表达值增高,差异有统计学意义（P＜0.05）.相关性检验显示GOLPH3蛋白的表达值与肿瘤的病理分级呈正相关（rs=0.961,P=0.000）.结论 GOLPH3在不同级别的胶质瘤组织中均有表达,其表达值与肿瘤的病理分级呈正相关,可能是胶质瘤发生发展的重要机制之一.

英文摘要：

Objective To investigate the expression of GOLPH3 in the tumor tissues of patients with gliomas and evaluate its clinical significance. Methods Seventy-six patients with brain gliomas （13 with grade Ⅰ, 27 grade Ⅱ, 25 grade Ⅲ and 11 with glioblastoma） performed surgical excision in our hospitals from July 2008 to December 2009 were chosen and 9 cases of normal brain tissues from patients performed decompression operation resulting from cerebral hernia were selected as the controls in our experiment. RT-PCR and Western-blotting were used to detect the mRNA and protein expressions of GOLPH3. Results The results investigated by RT-PCR and Western-blotting were consistent,revealing that the mRNA and protein expression rate of GOLPH3 in glioma tissues was not significantly different between different grades of tumors （P〉0.05）, but their expression value was obviously significant between different grades of tumors and increased in a grade-dependent manner （P〈0.05）. And minimal mRNA and protein expressions of GOLPH3 were found in the tissues of controls. The up-regulative protein expression of GOLPH3 was positively correlated to the malignancy-grade of the gliomas （r,=0.961, P=0.000）. Conclusion The mRNA and protein expressions of GOLPH3 are noted with positive correlation to the pathological grades of the gliomas, indicating th at GOLPH3 may play an important role in the generation and development of gliomas.
