Vitamin D protects the prostate

The June 15, 2008 issue of the International Journal of Cancer published the discovery of researchers at the University of Rochester that vitamin D exerts a protective effect on prostate cells against excess DNA-damaging oxidative stress that can lead to cancer.

While examining the antioxidant effect of vitamin D suggested by a number of studies, Rochester Medical Center associate professor of urology Yi-Fen Lee and colleagues found that the active form of vitamin D (1-alpha, 25-dihydroxyvitamin D3) protected cultured nonmalignant prostate epithelial cells from oxidative stress-induced cell death, while failing to protect prostate cancer cells. The team discovered that the activity of a gene controlling the expression of an important antioxidant enzyme known as glucose-6-phosphate dehydrogenase was increased by vitamin D in a dose and time dependent manner.

“If you reduce DNA damage, you reduce the risk of cancer or aging,” Dr Lee explained. “Our study adds one more beneficial effect of taking a vitamin D supplement. Taking a supplement is especially important for senior citizens and others who might have less circulation of vitamin D, and for people who live and work areas where there is less sunshine.”

“Vitamin D does not protect cancer cells from injury or damage, which is good,” she added.

Earlier research conducted by Dr Lee found that vitamin D can inhibit prostate cancer metastasis by reducing the activity of two enzymes known as matrix metalloproteinase and cathepsin. The finding suggests that vitamin D could be used as a treatment for prostate cancer patients who have elevated levels of these enzymes.

“Many epidemiological studies have suggested the beneficial properties of vitamin D,” Dr Lee observed. “Our findings reflect what we see in those studies and demonstrate that vitamin D not only can be used as a therapy for prostate cancer, it can prevent prostate cancer from happening.”

I hate prostate cancer!


Time to go get some sun.

I don't think I could handle the scorpions  :-X  That and the snakes are the two things that freak me out about that state.
