Fig. 9. Flow cytometry analysis for cell cycle distribution of MCF-7 cells. MCF-7 cells were treated with Taxol (8.24 μg mL⁻¹), GO (35.8 μg mL⁻¹), GO-EDTA (3.8 μg mL⁻¹), and GO-CS (23.1 μg mL⁻¹) or medium for 48 h. (A) Control, (B) Taxol, (C) GO, (D) GO-EDTA and (E) GO-CS treated cells. (F) A graphical illustration of cell cycle distribution analysis among different treated cells. * Significant P-value from control group at p < 0.01, # significant P-value from Taxol group at p < 0.01.
