CHST4 and hepatocellular carcinoma: Therefore, based on this data from previous studies (combined with the complementary sequences and expressions of miR-10b-5p, CHST4, and FENDRR in HBV-HCC), we speculate that the FENDRR–miR-10b-5p–CHST4 network plays an important role in HBV-HCC, although further experiments are necessary to prove this hypothesis.
