CircCPSF6 functioned as a novel m6A-modified circRNA accelerating tumorigenicity and cell metastasis of HCC by competitively binding to PCBP2, thus weakening the PCBP2-induced destabilization of YAP1 and triggering its expression, further activating its downstream cascade (24). This evidence concerns the gene PCBP2 and hepatocellular carcinoma.
