Concentration of superoxide dismutase 1 (SOD1) and activity of SOD in MCF-7 cells treated by DOX, C60 and C60–DOX complexes. Concentration of SOD1 in MCF-7 cells treated by (A) DOX, (B) C60, (C) complexes of C60–DOX. Activity of SOD in MCF-7 cells treated by (D) DOX, (E) C60, (F) complexes of C60–DOX. C60—fullerene, DOX—doxorubicin. For other experimental conditions, see Material and Methods. a p < 0.05 when compared to control cells; b p < 0.05 when compared to cells treated by 1 µM DOX; c p < 0.05 when compared to cells treated by 25 mg/mL C60; d p < 0.05 when compared to cells treated by C60–DOX complexes (25 mg/mL C60-1 µM DOX); e p < 0.05 when compared to cells treated by C60–DOX complexes (50 mg/mL C60-1 µM DOX).
