Core tip: HepG2.2.15 cells were treated with different concentrations of suberoylanilide hydroxamic acid (SAHA). Hepatitis B surface antigen (HBsAg) and hepatitis B e antigen (HBeAg) content were measured using chemiluminescence. Reverse transcription polymerase chain reaction was performed to measure hepatitis B virus (HBV) DNA in cell lysate. Results found that, the inhibitory effect of SAHA on cell proliferation was both time- and dose-dependent. After 24 h of treatment, the early cell apoptotic rate increased. After 48 h of treatment, HBsAg and HBeAg content both increased. Furthermore, HBV DNA content increased. In combination with anti-HBV drugs, SAHA may potentially be used cautiously for treatment of hepatocellular carcinoma.
