We have previously shown that dietary inositol hexakisphosphate (IP6) and myo-inositol prevent fatty liver in rats fed a casein-based diet containing 1,1,1-trichloro-2,2-bis (p-chlorophenyl) ethane (DDT). This study was performed to examine the comparative effects of dietary equimolar amounts of sodium IP6 (1.02%) and myo-inositol (0.2%) on the development of DDT-induced fatty liver and hypercholesterolemia in rats fed 20% casein-type amino acid mixtures designed to exclude a possible myo-inositol contaminant in casein. Thirty-six male Wistar rats were divided into 6 groups of 6 rats each for: a control group, myo-inositol-supplemented group, IP6-supplemented group, DDT-treated group, DDT + myo-inositol-supplemented group, and a DDT + IP6-supplemented group. Dietary IP6 clearly suppressed the rises in serum concentrations of cholesterol and phospholipids because of DDT feeding, but myo-inositol had no significant influence on such elevations. Dietary IP6, but not myo-inositol, caused significant body weight gain with or without DDT intake. Supplemental IP6 and myo-inositol significantly increased hepatic-free myo-inositol regardless of DDT intake and prevented fatty liver in rats fed DDT. In conclusion, dietary IP6 and myo-inositol exert similar effects on DDT-induced fatty liver and myo-inositol status but distinct effects on DDT-induced hypercholesterolemia and growth rate in rats fed casein-type amino acid mixtures.

The toxicity of p,p'-dichlorodiphenyldichloroethylene (p,p'-DDE), a contaminant and metabolite derivative of DDT [1,1,1-trichloro-2,2-bis(p-chlorophenyl)ethane] is partially mediated by reactive oxygen species. Protein cysteine-based regulatory switches and subsequent alterations of the overall hepatic metabolism are triggered by p,p'-DDE through the disruption of the cellular redox status. The consequences are reproductive impairment, metabolic disorders, diabetes, neurotoxicity and cancer. In recent years, the risk of p,p'-DDE exposure has increased worldwide, reflecting the rise of mosquito-borne diseases in tropical countries that produce and export contaminated foods. Selenium (Se) is an essential trace element in animal nutrition with antioxidant properties that protects against the toxicity of some xenobiotics. We analyzed the ability of diet Se-supplementation to prevent damages induced by p,p'-DDE in the liver of M. spretus mice, by using redox proteomics based on the determination of the redox status of protein Cys residues. Se selectively acted on specific target, restoring the redox status and functionality of some membrane proteins involved in mitochondrial functionality, protein transport, cell signaling and protein metabolism. However, the Se-enriched diet did not completely prevent the metabolic shift caused by p,p'-DDE exposure that leads to disturbed lipogenesis, hepatic steatosis and alterations in the synthesis of hormones and other cell signals.
