For example, HCH induced oxidative stress in Ehrlich Ascites tumor cells was studied by Srivastava and Shivanandappa [42], their results could be characterized by glutathione depletion, lipid peroxidation (LPO), reactive oxygen species (ROS) production and inhibition of antioxidant enzymes, superoxide dismutase (SOD) and catalase (CAT). Here, SOD1 is linked to neoplasm.
