Red wine may protect against radiation exposure

Washington, Sept 24 : A natural antioxidant commonly found in red wine, may offer protection against radiation exposure, according to a study by the University of Pittsburgh School of Medicine.

When altered with acetyl, resveratrol (the antioxidant) administered before radiation exposure proved to protect cells from radiation in mouse models, the researcher found.

The study has been presented during the American Society for Therapeutic Radiology and Oncology's (ASTRO) 50th Annual Meeting in Boston.

The study, led by Joel Greenberger, M.D., professor and chairman of the Department of Radiation Oncology at the University of Pittsburgh School of Medicine, is overseen by Pitt's Center for Medical Countermeasures Against Radiation.

The center is dedicated to identifying and developing small molecule radiation protectors and mitigators that easily can be accessed and administered in the event of a large-scale radiological or nuclear emergency.

"New, small molecules with radioprotective capacity will be required for treatment in case of radiation spills or even as countermeasures against radiological terrorism," said Dr. Greenberger.

"Small molecules which can be easily stored, transported and administered are optimal for this, and so far acetylated resveratrol fits these requirements well," the expert added.

"Currently there are no drugs on the market that protect against or counteract radiation exposure. Our goal is to develop treatments for the general population that are effective and non-toxic," he added.
