Activators of SIRT1 in wound repair: an animal model study.

Caloric restriction (CR) and resveratrol activate SIRT1 and induce anti-inflammatory and antioxidant properties. We perform excisional lesion on the dorsum of four groups anesthetized animals: ad libitum-AL diet, AL diet with topical application of 2% resveratrol-Rv, 30% calorie restricted, and finally 30% calorie restricted with 2% resveratrol and we examine CR and Rv effects in wound repair. Restricted animals remained with CR for 31 days.
