转化生长因子β(Transforming growth factor β,TGF-β)是肝细胞癌(hepatocellular carcinoma,HCC)上皮间质转化(epithelial-mesenchymal transition,EMT)的强诱导因子,在HCC的发生、发展中起重要作用。越来越多的证据表明,蛋白质编码mRNA和非编码RNA(ncRNA)在HCC的发生和发展中可能起着关键作用。在这项研究中,我们首次报道了用TGF-β或DMSO处理7天的Huh 7细胞中lncRNA、mRNA、miRNA和circRNA的差异表达。对显着差异表达的RNA(DE RNA)进行基因本体论(GO)和京都基因和基因组百科全书(KEGG)途径分析。预测并构建了基于这些DERNA的竞争性内源RNA(ceRNA)网络。其中,我们发现lncRNA SLC 7A 11-AS 1和hsa_circ_0006123参与TGF-β诱导的EMT过程,并可能促进HCC的转移。这些知识可能为开发新的临床诊断和治疗方法铺平道路。我们的研究可能为进一步研究TGF-β诱导HCC EMT过程的分子机制开辟了新的途径。
Transforming growth factor β (TGF-β) is a potent inducer of epithelial-mesenchymal transition (EMT) in hepatocellular carcinoma (HCC), and plays a critical role in its tumorigenesis and progression. Accumulating evidence indicates that protein-coding mRNAs, as well as non-coding RNAs (ncRNAs), may play key roles in the tumorigenesis and progression of HCC. In this study, we first report on the differential expression of lncRNAs, mRNAs, miRNAs, and circRNAs in Huh7 cells treated with TGF-β or DMSO for 7 days. Gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analyses were performed for significantly differentially expressed RNAs (DE RNAs). Then the competing endogenous RNA (ceRNA) network based on these DE RNAs was predicted and constructed. Among them, we identified that lncRNA SLC7A11-AS1 and hsa_circ_0006123 are involved in the EMT process induced by TGF-β and may promotes the metastasis of HCC. This knowledge may pave the way to develop novel clinical diagnostics and therapeutic approaches. Our study might open a new avenue for future investigations of the molecular mechanisms driving the EMT process induced by TGF-β in HCC.
