Flow cytometry analysis on cell cycle progression in A549 cells was carried out after incubation with AMEAE for (A) 0, (B) 24, (C) 48 and (D) 72 h. (E) Representative bar chart demonstrated significant cell cycle arrest at the G1 phase. The data represent the means ± SEM of three independent experiments. *p < 0.05 compared with the no-treatment group.
