Effects of lipids and antioxidants on PCB-mediated dysfunction of vascular endothelial cells (EC)

Our findings suggest that exposure to specific environmental contaminants can trigger diseases of the vasculature, e.g., cardiovascular disease. In addition, high-fat diets may potentiate and diets high in antioxidant nutrients may protect against PCB-mediated endothelial cell dysfunction. Our data give an insight into the potential use of vitamin E and related antioxidants to limit PCB-mediated cell injury. These studies are significant for providing new insights into potential nutrition interventions in diseases that can be induced by the toxicity of PCBs and other halogenated compounds.
