Effects of HCT on cell-cycle transition in human lung cancer A549 cells. (A) The A549 cells were treated with HCT (0, 125, 250 and 500 μg/ml) for 24 h, and then were harvested for determination the distribution of cell cycle by flow cytometry and (B) quantitative results were expressed as described in Materials and Methods. The experiments were performed in triplicate (n = 3). Data represents mean ± S.D. of three experiments. ***p < 0.001 was considered significantly different in comparison with the control.
