Fig. 10. Effects of GO, GO-EDTA and GO-CS on the caspase-8 and caspase-9 activity (A and B, respectively) in MCF-7 cells compared to Taxol. 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. Data are represented as mean ± SD, *: significant from control group at P value < 0.0001.
