Effect of EEL treatment on cell apoptosis and cell cycle distribution. Bel-7402 and Huh-7 cells in control, EEL1, EEL2 and EEL3 groups were respectively treated with 0, 25, 50 and 75 mg/ml EEL for 24 h. a, b Cell apoptosis and cell cycle distribution in Bel-7402 were detected using FCM. c, d Cell apoptosis and cell cycle distribution in Huh-7 were detected using FCM. Data were shown as mean ± S.D. for three independent experiments. ^*P < 0.05, ^**P < 0.01 versus control
