We aim to identify differentially expressed pseudogenes and investigate their functional roles in carcinogenesis.
MATERIALS & METHODS: Here, we identify dysregulated pseudogenes, analyze their prognostic values and investigate their potential functions through pseudogene-miRNA-mRNA network from public -omics repositories.
We identified 16 frequently upregulated pseudogenes among which high expression levels of RP11-564D11.3 was significantly associated with poor overall survival in seven types of human cancers. RP11-564D11.3 was strongly correlated with pathways in cancer, PI3K-Akt signaling pathway and the neurotrophin signaling pathway. Further studies revealed that RP11-564D11.3 functions as a competitive endogenous RNA through targeting VEGFA in hepatocellular carcinoma.
Our findings suggest RP11-564D11.3 as a novel biomarker and therapeutic potential target against hepatocellular carcinoma.
我们旨在鉴定差异表达的假基因,并研究它们在肿瘤发生中的功能作用。
在这里,我们通过公共组学数据库中的假基因-miRNA-mRNA 网络,鉴定失调的假基因,分析它们的预后价值,并研究它们的潜在功能。
我们鉴定出 16 个经常上调的假基因,其中 RP11-564D11.3 的高表达水平与七种人类癌症的总生存期不良显著相关。RP11-564D11.3 与癌症途径、PI3K-Akt 信号通路和神经生长因子信号通路强烈相关。进一步的研究表明,RP11-564D11.3 通过靶向肝细胞癌中的 VEGFA 作为竞争性内源性 RNA 发挥作用。
我们的研究结果表明,RP11-564D11.3 可以作为一种新的生物标志物和治疗靶点,用于治疗肝细胞癌。
