One of the causes for aging is free radical damage. Resveratrol (RSV), a polyphenolic compound has been shown to act as an antioxidant and anti-inflammatory. The objective this study was to verify in an oxidative stress environment in Human Mononuclear cells from Middle aged and Elderly donors, the existence of a change in the SIRT1 and AMPK signaling pattern by RSV. In both age groups there was a reduction in reactive oxygen species (ROS) in cells stimulated with RSV. It was observed that in the Elderly group there was a higher production of ROS and that the reduction from RSV was smaller compared to the other group. There was an increased activity of Superoxide Dismutase in cells exposed to RSV in the elderly group. It was observed that for the Middle Aged group, SIRT 1 and AMPK are antioxidant pathways and RSV acts via SIRT1. In the elderly, the SIRT1 remains antioxidant and RSV ceases its operation via SIRT1. RSV has an antioxidant action in both age groups, and that in aging there was a change in the cellular context characterized by the silencing of the AMPK pathway antioxidant character.
