In this respect, circ-CDYL, circASAP1, circSLC3A2, circRHOT1, circMAT2B, and circMALAT1 have been documented as enhancers in HCC, while circMOT1, cSMARCA5 and circTRIM33-12 reportedly act as competing endogenous RNAs (ceRNAs) to suppress HCC progression [11–18]. This evidence concerns the gene CDYL and hepatocellular carcinoma.
