PTEN Mediates the Antioxidant Effect of Resveratrol at Nutritionally Relevant Concentrations

<table>Resveratrol upregulates the expression of catalase (a) and MnSOD (b) in MCF-7 cells. Resveratrol (1 nM) increased mRNA levels of catalase and Mn-superoxide dismutase (<svg height="13.95" id="M5" style="vertical-align:-0.30096pt" version="1.1" viewbox="0 0 66.324997 13.95" width="66.324997" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink">
