Antioxidants show promise for reducing prostate cancer risk. To understand the mechanism
of this protection, Ripple et al. (p. 1227) studied the effect of antioxidants
vitamins C and E on several male hormone (androgen)-induced changes in a human prostate
carcinoma cell line. Androgens increased both reactive oxygen species levels and the
DNA-binding activity of transcriptional activators AP-1 and NF-
B, which are sensitive to
oxidative stress. These effects were blocked by the antioxidants. The authors note that further
studies are needed to understand the pathways involving androgens,
