Bethesda, MD–Cheers! A new research report appearing in the October 2011 issue of The FASEB Journal (https://www.fasebj.org) shows that resveratrol, the “healthy” ingredient in red wine, stops breast cancer cells from growing by blocking the growth effects of estrogen. This discovery, made by a team of American and Italian scientists, suggests for the first time that resveratrol is able to counteract the malignant progression since it inhibits the proliferation of hormone resistant breast cancer cells. This has important implications for the treatment of women with breast cancer whose tumors eventually develop resistance to hormonal therapy.
“Resveratrol is a potential pharmacological tool to be exploited when breast cancer become resistant to the hormonal therapy,” said Sebastiano Andò, a researcher involved in the work from the Faculty of Pharmacy at the University of Calabria in Italy.
Resveratrol may help protect against breast cancer by blocking the growth effects of estrogen.
To make this discovery, Andò and colleagues used several breast cancer cell
expressing the estrogen receptor to test the effects of resveratrol. Researchers then treated the different cells with resveratrol and compared their growth with cells left untreated. They found an important reduction in cell growth in cells treated by resveratrol, while no changes were seen in untreated cells. Additional experiments revealed that this effect was related to a drastic reduction of estrogen receptor levels caused by resveratrol itself.
“These findings are exciting, but in no way does it mean that should people go out and start using red wine or resveratrol supplements as a treatment for breast cancer,” said Gerald Weissmann, M.D., Editor-in-Chief of The FASEB Journal. “What it does mean, however, is that scientists haven’t finished distilling the secrets of good health that have been hidden in natural products such as red wine.”

The FASEB Journal(https://www.fasebj.org) is published by the Federation of the American Societies for Experimental Biology (FASEB) and celebrates its 25th anniversary in 2011. Over the past quarter century, the journal has been recognized by the Special Libraries Association as one of the top 100 most influential biomedical journals of the past century and is the most cited biology journal worldwide according to the Institute for Scientific Information.
FASEB comprises 24 societies with more than 100,000 members, making it the largest coalition of biomedical research associations in the United States. FASEB enhances the ability of scientists and engineers to improve–through their research–the health, well-being and productivity of all people. FASEB’s mission is to advance health and welfare by promoting progress and education in biological and biomedical sciences through service to our member societies and collaborative advocacy.
