Figure 4: Different concentrations of blueberry polyphenols affected different phases of cell cycle. Cells were treated with vehicle or 12.5-50 μg/ ml of polyphenols for 96 h. DNA was stained with propidium iodide and cell cycle distribution was detected using flow cytometry. A) Indicates the effect on G0/G1-phase (b:p<0.05, c:p<0.001, cb:p<0.001). B) Depicts changes on S-phase (p<0.001). C) Represents the effect on G2/M-phase (P<0.01). Data are reported as the mean ± SEM of 5 independent experiments. Means that do not share letters are significantly different from each other.
