  • Title: Lipid peroxidation as a possible cause of TCDD toxicity.
    Author: Stohs SJ, Hassan MQ, Murray WJ.
    Journal: Biochem Biophys Res Commun; 1983 Mar 29; 111(3):854-9. PubMed ID: 6838590.
    Abstract:
    The target tissues of TCDD, the dysfunctions that result in death in experimental animals, and the ultimate biochemical lesion(s) caused by TCDD are not known despite numerous studies. We have shown by the thiobarbituric acid and conjugated diene methods that TCDD induces hepatic lipid peroxidation in rats. The lipid peroxidation produced by TCDD is both dose and time dependent. A 5-6 fold increase in lipid peroxidation occurs within 6 days following the administration of 40 micrograms TCDD/kg body weight/day for 3 days. Thus, the toxicity of TCDD may be caused in part by free radical-mediated lipid peroxidation that leads to general cell membrane damage which can ultimately produce death in experimental animals at acutely toxic doses.
