目的 检测非转移性细胞蛋白1基因(NME1基因)在前列腺癌组织中的表达,探讨NME1在前列腺癌中的分子机制和临床意义.方法 应用基因芯片筛选出在前列腺癌与前列腺增生组织特异性表达的基因NME1,运用蛋白组学检测前列腺癌组织标本54例、癌旁组织29例、组织中NME1基因结合蛋白差异表达程度.免疫组织化学结合NME1免疫组织化学评分对前列腺癌患者的临床病理参数进行分析.结果 通过基因芯片筛选,可见NME1在前列腺癌组织中表达上调,达2.24倍(P<0.01).双向差异凝胶电泳(2D-DIGE)技术亦发现相对于癌旁组织NME1基因结合蛋白在前列腺癌组织中表达上调,达2.36倍(P<0.01).通过免疫组织化学染色,可见NME1在前列腺癌组织中的表达明显强于癌旁组织(P<0.01),在前列腺癌并转移组织中的表达亦明显强于原位前列腺癌组织(P<0.01).NME1表达与前列腺癌患者血清前列腺特异抗原(PSA)水平(P<0.05)、Gleason评分(P<0.01)和肿瘤TNM分期(P<0.05)、是否转移(P<0.01)呈正相关,而与患者年龄无明显相关(P>0.05).NME1阳性的前列腺癌患者预后不良(Log Rank=11.117,P<0.01).结论 NME1低表达与肿瘤的恶性程度相关,NME1缺失可能导致恶性肿瘤细胞迅速生长,可结合血清PSA水平对前列腺癌疑似患者进行早期诊断及初步判断肿瘤恶性程度.

Objective To explore the role of non metastatic cell protein 1 (NME1) in diagnosing prostate cancer (PCa) and judging early metastasis of PCa.Methods The gene chip was used to screen NME1 in PCa and benign prostatic hyperplasia (BPH) tissues,the differential expression of NME1 prostein in PCa and adjacent tissues was analyzed by using fluorescence 2-D difference gel electrophoresis (2DDIGE) technology,and validated by using immunohistochemistry (IHC).The NME1 IHC score and clinicopathological parameters of PCa patients were analyzed.Results Relative to BPH tissues the expression of NME1 was down-regulated in PCa tissues by gene chip screening (P < 0.01),and relative to adjacent tissues the same phenomenon was observed in PCa tissues by using 3D-DIGE technology (P <0.01).The expression of NME1 was negatively correlated with serum PSA levels (P < 0.05),Gleason score (P <0.01) and TNM stage (P < 0.05),positively correlated with metastasis (P < 0.01),but not correlated with age (P > 0.05).NME1-positive PCa patients had a lower overall survival rate (Log Rank =11.117,P <0.01),but there was no significant difference in biochemical recurrence rate between NMEl-negative and NMEl-positive PCa patients (Log Rank =0.247,P > 0.05).Conclusion The low expression of NME1 is closely related with the malignancy of PCa,and the loss of NME1 may promote tumor cell growth.Serum PSA levels in combination with NME1 levels can be used to diagnose PCa early and judge the degree of the malignancy of PCa.The high expression of NME1 may promote PCa metastasis.
