In hepatitis B virus (HBV)-associated hepatocellular carcinoma, the hsa_circ_0067934 acts as a sponge for the miR-1324, thus, altering the FZD5/Wnt/β-catenin signalling pathway, which participates in the proliferation, migration, and invasion of the HBV-associated hepatocellular carcinoma [69]. The gene discussed is FZD5; the disease is hepatocellular carcinoma.
