Iron deficiency prevents liver toxicity of 2,3,7,8-tetrachlorodibenzo-
p-dioxin.
The compound 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) causes
hepatocellular damage and porphyria in C57B1/6J mice, among a wide
range of toxic effects. We compared the effect of TCDD toxicity in
iron-deficient mice with that in mice receiving a normal diet.
Porphyria did not develop in the iron-deficient animals, and these
animals were also protected from hepatocellular damage and certain
other toxic effects of TCDD. PMID: 432648
