Breast Cancer Growth Stopped by Resveratrol in Red Wine

A new study reported in the October issue of the Federation of the American Societies for Experimental Biology (FASEB journal) concluded that resveratrol in red wine stops breast cancer cells from growing by blocking the growth effects of estrogen. These findings vary from earlier findings about red wine and cancer. The researchers used several breast cancer cell lines expressing the estrogen receptor to test the effect of resveratrol. Comparing the growth of cells treated with resveratrol to those untreated they found an important reduction in cell growth in the cells treated with resveratrol but no reduction in growth of the untreated cells. Additional studies showed that this reduction in growth was related to a drastic reduction of estrogen receptor levels caused by the resveratrol. The authors concluded that although these findings are exciting, “in no way does it mean that people should go out and start drinking red wine or resveratrol supplements as a treatment for breast cancer.”
