PD induces S-phase arrest in SKM-1 and MUTZ-1 cells (n = 3). (A) and (B)Representative flow cytometry images. (C) and (D) Percentages of SKM-1 and MUTZ-1 cells in each phase of the cell cycle, respectively, after treatment with PD (0, 10, or 30 µmol) for 48 h. The values are expressed as the means ± SEMs. *p < 0.05, ****p < 0.0001.
