Vitamin E Inhibits Prostate Cancer

TAMPA, Fla.--Vitamin E succinate (VES), a vitamin E analogue, inhibited prostate cancer in vitro and in an animal model, according to a study published in the International Journal of Cancer (118,10:2441-47, 2006).

Researchers from the H. Lee Moffitt Cancer Center & Research Institute and Southern Illinois University School of Medicine found VES time- and dose-dependently inhibited proliferation and induced apoptosis in prostate cancer cell lines and a xenograft model of prostate cancer. In addition, daily injections of the vitamin E analogue inhibited prostate tumor growth as well as lung metastases in mice.

The researchers concluded these results suggest a potential therapeutic utility of VES for patients with prostate cancer.
