For example, it has been reported that cSMARCA5 (circular RNA of SMARCA5) acts as a sponge for miR‐17‐3p and miR‐181b‐5p to inhibit the proliferation and migration of HCC cells, whereas SMARCA5 (mRNA of SMARCA5) activates the Wnt/beta‐catenin signaling pathway to promote HCC proliferation.25 The gene discussed is CTNNB1; the disease is hepatocellular carcinoma.
