Modulation of Tamoxifen Cytotoxicity by Caffeic Acid Phenethyl Ester in MCF-7 Breast Cancer Cells

Figure 8

Glutathione (GSH) and nitric oxide (NO) levels in MCF7 cells following 48 h treatment. (a) Effect of treatment with 10 μM TAM, 4 μM CAPE, and their combination on glutathione (GSH) level in MCF-7 cells. The columns represent nmol GSH/mg protein. (b) Effect of treatment with 10 μM TAM, 4 μM CAPE, and their combination on nitric oxide (NO) level in MCF-7 cells. The columns represent μg/mL nitrate. The values were represented as means ± SD of three separate experiments. A: significantly different from the control group at . B: significantly different from TAM group at .
