研究表明,长链非编码RNA (lncRNA)具有调节代谢的作用;然而,代谢途径‐相关lncRNA癌中的表达谱尚不清楚。本研究的目的是研究代谢途径相关lncRNA癌中的作用及其可能的诊断价值。

利用代谢通路相关lncRNA芯片检测胃癌和配对非肿瘤组织中代谢通路相关lncRNA的差异表达模式。RP11555H23.1是一种具有代表性的代谢通路‐相关lncRNA,通过定量实时逆转录‐聚合酶链反应(qRTPCR)验证了其表达。分析RP1155H23.1表达与胃癌患者临床病理特征的关系。进一步建立了接收者工作特性曲线。

在肿瘤组织和非肿瘤组织中共发现114个差异表达的代谢通路‐相关lncRNA(>2的倍数变化,P < 0.05) (GEO NoGSE96856)。其中TUG1RP11555H23.1RP1257I20.13UGP2GCSHP3XLOC_000889 lncRNA在胃癌组织中下调超过6倍。相比之下,胃癌组织中RP11605F14.2TBC1D3P5BC130595LINC00475RP1119P22.6BC080653XLOC_004923AFAP1AS1EPB49RP11296I10.3 lncrna的上调幅度超过6倍。我们进一步证明RP11555H23.1表达与TNM分期显著相关(P = 0.038)ROC曲线下面积(AUC)0.65,特异性和敏感性分别为62%81%

代谢通路相关lncrRNA在胃癌的发生过程中发挥着重要作用,而代谢通路相关lncRNA,如RP11555H23.1,可能是胃癌新的生物标志物。

Brit J Cancer:GAS5肿瘤抑制因子lncRNA功能丧失研究

膀胱癌(BlCa)遗传异质性和个性化预后的缺乏导致了患者治疗结果的高度可变性。最近,有研究人员分析了GAS5肿瘤抑制因子lncRNA在改善BlCa预后中的作用。研究人员在一个176名患者组成的筛选群体中对GAS5进行了定量,并将Hedegaard et al.(2016)文章中的476名和TCGA临时性群体(n=413)作为鉴定群体。研究人员还使用复发和恶化对NMIBC进行了生存分析,并利用死亡数
