ETME synergized with As2O3 to induce cell cycle arrest in SMMC-7721 cells. (A) The cell cycle progress of SMMC-7721 cells was detected after treatment with ETME, As2O3 or their combination for 48 h. Data are expressed as mean±SD, n=3. *P<0.05, **P<0.01 vs control. (B) The protein expression of SMMC-7721 cells was detected after treatment with ETME, As2O3 or their combination for 48 h. β-actin is used as a loading control.
