Plant compound resveratrol shown to suppresses inflammation, free radicals in humans
Date:7/29/2010

BUFFALO, N.Y. -- Resveratrol, a popular plant extract shown to prolong life in yeast and lower animals due to its anti-inflammatory and antioxidant properties, appears also to suppress inflammation in humans, based on results from the first prospective human trial of the extract conducted by University at Buffalo endocrinologists.

Results of the study appear as a rapid electronic publication on the Journal of Clinical Endocrinology & Metabolism website and will be published in an upcoming print issue of the journal.

The paper also has been selected for inclusion in Translational Research in Endocrinology & Metabolism, a new online anthology that highlights the latest clinical applications of cutting-edge research from the journals of the Endocrine Society.

Resveratrol is a compound produced naturally by several plants when under attack by pathogens such as bacteria or fungi, and is found in the skin of red grapes and red wine. It also is produced by chemical synthesis derived primarily from Japanese knotweed and is sold as a nutritional supplement.

Husam Ghanim, PhD, UB research assistant professor of medicine and first author on the study, notes that resveratrol has been shown to prolong life and to reduce the rate of aging in yeast, roundworms and fruit flies, actions thought to be affected by increased expression of a particular gene associated with longevity.

The compound also is thought to play a role in insulin resistance as well, a condition related to oxidative stress, which has a significant detrimental effect on overall health.

"Since there are no data demonstrating the effect of resveratrol on oxidative and inflammatory stress in humans," says Paresh Dandona, MD, PhD, UB distinguished professor of medicine and senior author on the study, "we decided to determine if the compound reduces the level of oxidative and inflammatory stress in humans.

"Several of the key mediators of insulin resistance also ar
