Effect of treatments on cell cycle of MCF7 and HepG2 cells. A Cell cycle graphs as evaluated by flow cytometry (X-axis: PI fluorescence reflecting DNA content, and Y-axis: cell count). B Percentage of cells in subG0/G1, G0/G1, S, and G2/M phase. Values are expressed as mean ± SEM, n = 3. Various letters [a (highest value)–f (lowest value)] denote significant differences at P < 0.05. All groups were compared to each other
