Clues on Vitamin E's Anti-Prostate Cancer Effects
(New York, Reuters Health, 5/29/02)

Dr. Shuyuan Yeh of the University of Rochester Cancer Center and fellow researchers report that Vitamin E protects against prostate cancer by inhibiting the production of both PSA (Prostate Specific Antigen) and AR, the androgen receptor which is the receptor for testosterone. Fewer androgen receptors render the cell less able to turn on prostate cancer genes.
