Abstract

The role of antioxidants in prevention and treatment of cancers have been reported by several studies. In our investigation we studied the effects of ascorbic acid, α-tocopherol, and sodium selenite on proliferation of two breast cancer cell lines: T47D (estrogen-receptor positive) and MDA-MB-231 (estrogen-receptor negative). We also used 17-β-estradiol as positive control for proliferation of T47D cells. The viability of cells after 7 days of exposure to different concentrations of test compounds was determined by resazurine based method. Ascorbic acid and α-tocopherol significantly inhibited cell growth at a concentration of 10^-4 M in both cell lines and antagonized the cell proliferation induced by 17-β-estradiol in T47D cells. Sodium selenite at concentrations above 10^-6M strongly inhibited the cell growth in both cell lines and suppressed the stimulated growth of T47D cells by 17-β-estradiol. Our results with different strengths of activity of test compounds, further confirmed the findings of previous studies that showed the inhibitory effects of these antioxidants on other malignant cell lines.
