摘要
背景:长非编码RNA(lncRNA)是一种调节性RNA,在众多细胞途径中起关键作用。 已指定这组非编码RNA的异位表达与多种疾病有关。 此外,已经确认lncRNA在包括结直肠癌(CRC)的癌症的引发和发展中的作用。 目的:在本综述中,lncRNAs作为CRC中预后和诊断生物标志物的作用以及其对CRC形成的贡献的分子机制已得到解决。 结果:目前的研究表明CRC中各种lncRNA的异位表达。 与健康对照组相比,一些被认为是抑癌基因的lncRNA在大肠癌组织中被下调。 然而,一些具有致癌作用的基因被上调。 LncRNA通过多种分子机制(例如表观遗传学控制靶基因的表达,与miRNA作为其海绵相互作用)来促进肿瘤的发展。 结论:已被认为是预后生物标志物的LncRNA可能为临床管理铺平道路,为CRC患者提供辅助治疗。
关键词: 生物标志物,结直肠癌(CRC),lncRNA,结直肠癌的诊断性生物标志物,CRC,支架因子。
