               【摘要】 背景 去势抵抗性前列腺癌(CRPC)是男性常见恶性肿瘤疾病之一,病死率高,分子机制仍不十分清楚,
           且无有效治疗药物。目的 应用生物信息学方法挖掘 CRPC 发生、发展的关键基因,为其诊治提供新思路。方法 从
           基因表达综合数据库(GEO)中下载关于人类原发性前列腺癌(PCa)和 CRPC 的数据集 GSE32269 并进行生物信息学
           分析。使用 R 语言鉴定 CRPC 的差异表达基因(DEGs)。通过 DAVID 软件对 DEGs 进行基因本体论(GO)富集分析
           及京都基因和基因组百科全书(KEGG)通路分析。利用 STRING 在线数据库构建蛋白质 - 蛋白质相互作用(PPI)网
           络进一步筛选关键基因,并对关键基因进行生存分析和受试者工作特征(ROC)曲线分析。结果 通过对微阵列数据
           集 GSE32269 分析共筛选出 279 个 DEGs,进一步通过 GO 富集分析和 KEGG 通路分析发现在 CRPC 发展中,细胞分裂、
           有丝分裂和细胞周期等信号通路发挥重要作用。PPI 网络分析筛选出 15 个关键基因,对关键基因进行生存分析发现:
           CDC20、MAD2L1 和 NUSAP1 高表达组 CRPC 患者总生存率和无病生存率均分别低于 CDC20、MAD2L1 和 NUSAP1 低
           表达组(P<0.05);且 CDC20、MAD2L1 和 NUSAP1 预测 CPRC 发生的 ROC 曲线下面积分别为 0.933、0.762、0.950,
           提示其对 CRPC 具有较高的诊断价值。结论 CDC20、MAD2L1 和 NUSAP1 可能是参与 CRPC 发展的关键候选基因。

               【Abstract】 Background Castration-resistant prostate cancer(CRPC) is one of the most prevalent cancers in males
           with a high fatality rate. Its molecular mechanism is still unclear,and there is no effective treatment. Objective To explore
           the key genes involved in CRPC development using bioinformatic analysis,offering new ideas for the diagnosis and treatment of
           CRPC. Methods The data set GSE32269 which contains human primary prostate cancer and CRPC was downloaded from the
           Gene Expression Omnibus database for further bioinformatic analysis. R language was used to identify differentially expressed
           genes(DEGs) in CRPC. Gene Ontology(GO) enrichment analysis and Kyoto Encyclopedia of Genes and Genomes(KEGG)
           pathway analysis of DEGs were further performed by using DAVID. A protein-protein interaction(PPI) network of DEGs was
           constructed by using STRING database for screening potential key genes. And the identified potential key genes were further
           analyzed by survival analysis and receiver operating characteristic(ROC) curve analysis. Results 279 DEGs were identified in
           microarray dataset GSE32269. GO enrichment analysis and KEGG pathway analysis revealed that cell division,mitosis and cell
           cycle signaling pathways may play an important role in the development of CRPC. PPI network screening revealed that there were
