Aberrant expression of lncRNAs drives tumorous invasion and metastasis. Whether lncRNAs engage mechanisms of liver cancer metastasis remains largely unexplored.Patients and Methods: We collected HCC tissues from the tumors and their adjacent normal samples in the Chinese population and analyzed the levels of lncRNAs by microarray analysis. The gain- and loss-of-function analysis demonstrated that PCBP1-AS1 accelerated tumorous growth and metastasis in vivo and in vitro. Moreover, we used RNA-pulldown assay to show that PCBP1-AS1 physically interacted with polyC-RNA-binding protein 1 (PCBP1); meanwhile, PCBP1-AS1 was indeed detected in RIP with the PCBP1 antibody. Mechanistically, we first explored the relationship between PCBP1‐AS1 and PCBP1 in HCC cell lines.Results: Here we show that PCBP1-AS1, identified by microarray analysis on pre- and post-operative HCC plasma specimens, was highly expressed in human HCC, clinically verified as a prometastatic factor and markedly associated with poor prognosis in patients with hepatocellular carcinoma. PCBP1‐AS1 was negatively related with PCBP1 at the messenger RNA and protein expression levels. PCBP1-AS1 triggered PRL-3 and AKT in HCC tumor cells. Additionally, the double knockout of PCBP1 and PCBP1-AS1 abolished the PCBP1-AS1-induced PRL-3-AKT signalling pathway activation.Conclusion: The upregulation of PCBP1-AS1 enhances proliferation and metastasis in HCC, thus regulating the PCBP1-PRL-3-AKT signalling pathway.Keywords: hepatocellular carcinoma, long non-coding RNA, PCBP1-AS1, poly(C)-binding protein 1, AKT, hepatocarcinogenesis, metastasis |
