SCI REP:ANLN有希望成为鉴定膀胱尿路上皮癌的预后生物标志物

2017-06-09 MedSci MedSci原创

通常对于具有相似病理特征的膀胱尿路上皮癌(BLCA)患者,预后往往也有很大差异。在这项研究中,我们对10对BLCA样品和相邻的正常组织进行了转录组测序,以鉴定差异表达的基因。与正常组织相比,Aillin(ANLN)的转录物在BLCA样品中显着上调。

通常对于具有相似病理特征的膀胱尿路上皮癌(BLCA)患者,预后往往也有很大差异。在这项研究中,我们对10对BLCA样品和相邻的正常组织进行了转录组测序,以鉴定差异表达的基因。与正常组织相比,Aillin(ANLN)的转录物在BLCA样品中显着上调。另外,又分别在40例和209例患者中使用qRT-PCR和免疫组织化学方法研究候选基因的预后潜力。 与ANLN的低表达相比,ANLN表达水平升高的患者与较差的癌症特异性(中位数,22.4 vs 37.3 months,p = 0.001),无进展生存期(中位数,19.7 vs 27.9 months,p = 0.001)和无复发生存期(中位数 ,17.1 vs 25.2 months,p = 0.011)相关联。并分析了公共数据集TCGA和NCBI-GEO进行外部验证。使用小干扰RNA敲除J82和5637细胞中的ANLN,显着抑制细胞增殖,迁移和侵袭能力。此外,敲低ANLN导致G2 / M期停滞,并降低细胞周期蛋白B1和D1的表达。微阵列分析表明,ANLN在细胞迁移中起主要作用,并与几种癌症相关信号通路密切相关。总之,ANLN有希望成为预后生物标志物,可用于不同风险BLCA的分层。
