PCBP1 and hepatocellular carcinoma: In addition, Polyc-RNA-Binding Protein [PCBP1] inhibits the invasion of HCC cells and has been identified as a potential tumor suppressor gene.[18] PCBP1-AS1 and PCBP1 are antisense RNAs for each other, which can complement specific nucleotide sequences of other transcripts and can play different roles in regulating the expression of target genes after transcriptional level by various mechanisms).
