By blocking a protein key to prostate cancer cell growth, researchers at the Lombardi Cancer Center at Georgetown University have discovered a way to trigger extensive prostate cancer cell death. This finding opens a new window for developing targeted treatments aimed at destroying prostate cancer cells before they have the opportunity to grow or spread. The study is published in the April 29 online issue of the Journal of Biological Chemistry.
An Australian study has found that a supplement derived from red clover causes early-stage prostate cancer cells to die in numbers five times greater than in an untreated control group. The findings may explain the mystery of why Asian men, who have pre-cancerous prostate cells at similar rates to men in Western countries, see a much smaller percentage of those cells become cancerous. One previously reported study, for example, finds that 1.8 percent of men in China develop prostate cancer versus 53.4 percent of U.S. males. These findings led researchers to consider dietary differences between the cultures, particularly isoflavones.
