Sci Rep:膀胱癌中作为预后因子的免疫相关基因鉴定

2020-11-25 AlexYang MedSci原创

膀胱癌是全球最常见的癌症之一。免疫反应和免疫细胞浸润在肿瘤进展中起着关键的作用。在过去十年,免疫治疗在膀胱癌方面取得了突破性的成就。

膀胱癌是全球最常见的癌症之一。免疫反应和免疫细胞浸润在肿瘤进展中起着关键的作用。在过去十年,免疫治疗在膀胱癌方面取得了突破性的成就。

最近,有研究人员通过使用edgeR软件包坚定了膀胱癌中的差异表达基因和免疫相关基因(DEIRGs),并使用基因本体注释和KEGG途径分析对DEIRGs进行了功能富集分析。研究人员还通过单变量Cox回归分析确定了生存相关的IRGs,并通过单变量COX回归分析建立了预后模型,且使用了基于GEO数据库的验证性预后模型进行了验证。研究人员根据免疫细胞浸润的风险评分中值和临床病理分析,将患者分为高危组和低危组,并构建了生存相关IRGs和潜在转录因子的调控网络,用来调查生存相关IRGs的潜在调控机制。最后用Nomogram和ROC曲线验证模型的准确性。研究结果表明,共发现了259个差异表达的IRGs。对IRGs的KEGG通路分析显示,"细胞因子-细胞因子受体相互作用 "通路是最显著富集的通路。研究人员选取13个与生存相关的IRGs建立了对膀胱癌的预后指数。在TCGA预后模型和GEO验证模型中,高风险分的患者与低风险分组相比预后更差。高风险患者中巨噬细胞的浸润水平更高。OGN、ELN、ANXA6、ILK和TGFB3确定为网络中生存相关核心IRGs。另外,EBF1、WWTR1、GATA6、MYH11和MEF2C参与了这些生存相关核心IRGs的转录调控。

相关关键基因的表达水平

最后,研究人员指出,他们的研究发现了几个具有临床意义的生存相关IRGs,并首次建立了膀胱癌结果评价的预后指标。
