Cell cycle distribution of viable MCTS cells in the G0/G1, G2 + M, and S phases of cell cycle. Flow cytometric cell cycle analysis was carried out after 4 days of treatment with E. scaber, tamoxifen citrate, and their combinatorial treatment. The population of dead cells in subG0/G1 was ignored in the calculation, and the percentage distribution of the nondead cells was adjusted to 100%. Recalculated percentages of the cells in each phase are presented as means ± SEM of three independent experiments: E. scaber ethanol extract 60 μg/mL (ES60), tamoxifen citrate 3.125 μg/mL (TC3), and tamoxifen citrate 6.25 μg/mL (TC6). ∗ Statistical significance () between control cells and treatment groups.
