长链非编码RNA ADAMTS9-AS1和AL109955.1在结直肠癌中的表达及生物学功能研究
发布时间:2021-01-29 23:36
目的:近年来,LncRNAs在肿瘤发生、发展中的调控作用备受关注,LncRNAs可通过外泌体由肿瘤细胞分泌到体液中发挥相应的生物学作用。有研究表明,外泌体中的LncRNA可能成为各种癌症诊断和预后的潜在生物标志物。在本研究中,我们通过分析TCGA数据,筛选结直肠癌发生和预后相关的差异LncRN As分子,通过体内外功能实验对其生物学作用进行分析,通过 Gene Ontology(GO)及 Kyoto Encyclopedia of Genes and Genomes(KEGG)富集分析预测并验证相关信号通路,最后检测其在结直肠癌(CRC)患者血清中的表达水平并明确其临床诊断价值。方法:通过对TCGA数据库中的结直肠癌测序数据进行分析,我们得到了14个在结直肠癌组织中低表达且与不良预后相关的LncRNAs分子作为候选分子:ADAMTS9-AS1,AL36536.1,KCNJ2-AS1,FGF14-AS2,AC129507.2,AC106739.1,MAFTRR,AL109955.1,TRHDE-AS1,AL136368.1,FO393418.1,LINC01571,AP003396.3 ...
