Future Diabetes Treatment May Use Resveratrol To Target The Brain

Summary:
A new study shows that the brain plays a key role in mediating resveratrol's anti-diabetic actions, potentially paving the way for future orally delivered diabetes medications that target the brain.

Resveratrol, a molecule found in red grapes, has been shown to improve diabetes when delivered orally to rodents. Until now, however, little has been known about how these beneficial changes are mediated in the body. A new study accepted for publication in Endocrinology, a journal of The Endocrine Society, shows that the brain plays a key role in mediating resveratrol's anti-diabetic actions, potentially paving the way for future orally-delivered diabetes medications that target the brain.

Resveratrol activates sirtuins, a class of proteins that are thought to underlie many of the beneficial effects of calorie restriction. Previous studies in mice have provided compelling evidence that when sirtuins are activated by resveratrol, diabetes is improved. Sirtuin activators are now being tested in humans as anti-diabetic compounds.

Sirtuins are expressed virtually everywhere throughout the body and until now, little has been known about what tissues mediate resveratrol's beneficial effects. Knowing where in the body the beneficial effects of activated sirtuins are mediated could help in the development of more effective targeted diabetes medications.

"We know that sirtuins are expressed in parts of the brain known to govern glucose metabolism, so we hypothesized that the brain could be mediating resveratrol's anti-diabetic actions," said Roberto Coppari, PhD, of the University of Texas Southwestern Medical Center and co-author of the study. "To test the hypothesis, we assessed the metabolic consequences of delivering resveratrol directly into the brain of diabetic mice. We found that resveratrol did activate sirtuins in the brain of these mice which resulted in improving their high levels of blood sugar and insulin."

"These findings may lead to new strategies in the fight against type 2 diabetes," said Coppari. "By knowing that the brain mediates resveratrol's anti-diabetic actions, industry can now focus on developing sirtuin activators that directly target the brain. When orally-delivered, these drugs will likely improve diabetes without affecting the other organs in which activation of sirtuins may not always be beneficial."

Other researchers working on the study include Giorgio Ramadori, Laurent Gautron, Teppei Fujikawa, Claudia Vianna and Joel Elmquist of the University of Texas Southwestern Medical Center in Dallas, Tex.

The article, "Central administration of resveratrol improves diet-induced diabetes," will appear in the December 2009 issue of Endocrinology.
