Blueberries may fight prostate cancer

 

 

 

 

Matrix metalloproteinases are enzymes that break down cellular tissue proteins such as collagen that lie in between cells. Because of the ability to knock down protective barriers these enzymes are active in cancer metastasis. These scientists investigated if blueberry polyphenols can inhibit these metalloproteinase enzymes in prostate cancer tissue and therefore help prevent the spread of this cancer. The blueberry polyphenols as it turns out work in various ways to inhibit these prostate cancer spreading enzymes. The polyphenols stimulate the release of metalloproteinase inhibitors within the cells and the polyphenols directly inhibit these cancer associated enzymes. The research was performed at the department of Biology, University of Prince Edward Island, in Canada, and is published in the August 2005 issue of The Journal of Nutritional Biochemistry.
