Michael Petriello, is a toxicology doctoral student working with Bernhard Hennig, Ph.D., at the University of Kentucky. Petriello is investigating the molecular mechanisms of PCB-induced cardiovascular disease and how bioactive nutrients, such as those found in green tea, can limit toxicant-induced oxidative stress, inflammation, and disease. Petriello and his colleagues have recently shown that green tea polyphenols such as EGCG can limit PCB-induced oxidative stress and vascular cell toxicity by upregulating the cellular antioxidant response. They hypothesize that a diet rich in fruits, vegetables, and omega-3 polyunsaturated fatty acids can better prepare us for toxicant exposure by priming our antioxidant defense. Petriello has a B.S. in biology and environmental science from Muhlenberg College.
