Fig. (8) Effects of glucose on CA-induced SOD-like activity in MCF-7 cells. (A): MCF-7 cells were incubated in the medium containing various concentrations (1.0 or 4.5 g/L) of D-glucose for 24 hours (Naive). (B): MCF-7 cells were incubated in the medium containing various concentrations (1.0 or 4.5 g/L) of D-glucose in the presence of 64 μM CA for 24 hours (CA treatment). The SOD-like activity was determined. All experiments were performed in triplicate, and values are indicated as mean ± S.D. Statistically significant differences are indicated by an asterisk (*p<0.05 by Student’s t-test).
