DNMT1 and hepatocellular carcinoma: -Reduced the viabilities of HCC cells but not L02 cells-Inhibited the stemness characteristics in HCC cells-Repressed DNMT1 activity and expression-Increased miR-148a-3p⇒ Casticin could inhibit stemness characteristics in HCC cells by interruption of the reciprocal negative regulation between DNMT1 and miR-148a-3p
