Polychlorinated biphenyls (PCBs) are ubiquitous and persistent environmental contaminants that disturb normal hormonal functions.Numerous toxic substances that are found in the urban environment cause abnormalities in normal growth and development. Exposure to PCBs leads to decreased antioxidant system and increased reactive oxygen species (ROS). Diets rich in vegetables protecting against several toxicants. Hence, the study was designed to investigate the role of lycopene on PCB induced cytotoxicity in rats. Mitochondrial membrane potential, LDH leakage assay, intrinsic and extrinsic pathway...
