The combination of As2O3 and siNrf2 induced G1 cell cycle arrest of 5-FU-resistant HCC cells. The cell cycle was analyzed using flow cytometry after treatment with or without 20 μM As2O3 for 24 h in (A–D) SNU-387/5-FU and (E–H) Hep3B/5-FU cells. All data are expressed as mean ± SEM. *P < 0.05; **P < 0.01; versus the control group. #P < 0.05; versus the indicated groups.
