TAP protein and dietary Vitamin E
As reported, A Protein That Helps Maintain Vitamin E Levels Suppresses Prostate Cancer, University of Rochester Medical Center researchers have found a protein that helps prostate cancer cells retain vitamin E. This helps vitamin E to limit the growth of the cancer.
The protein, which they call alpha tocopherol associated protein, or TAP, suppresses growth of the cancer by disrupting an important signaling pathway in prostate cancer cells.
A reader asks, for men with prostate cancer would it help to take a high quality vitamin E pill?
We don’t really know. Last year a controversial study from Johns Hopkins found that, especially in older people, consumption of current maximum dose of vitamin E was associated with a higher death rate.
