Iron, ferritin, and nutrition.
Ferritin, a major form of endogenous iron in food legumes such as soybeans, is a novel and natural alternative for iron supplementation strategies where effectiveness is limited by acceptability, cost, or undesirable side effects. A member of the nonheme iron group of dietary iron sources, ferritin is a complex with Fe3+ iron in a mineral (thousands of iron atoms inside a protein cage) protecte...
متن کاملEffect of Dietary Aluminum on Iron and Ferritin Metabolism
Aluminum (AI) toxicity is known to cause microcytic anemia, osteomalacia, and encephalopathy, but the mechanisms are poorly understood. Although Al is a neurotoxicant, its role in Alzheimer's disease remains controversial. One hypothesis for the toxicity of Al is that it disrupts cellular iron (Fe) homeostasis, causing iron to become cytotoxic. Cell culture studies have shown that Al suppresses...
متن کاملEffects of Exogenous Antioxidants on Dietary Iron Overload
In dietary iron overload, excess hepatic iron promotes liver damage. The aim was to attenuate free radical-induced liver damage using vitamins. Four groups of 60 Wistar rats were studied: group 1 (control) was fed normal diet, group 2 (Fe) 2.5% pentacarbonyl iron (CI) followed by 0.5% Ferrocene, group 3 (Fe + V gp) CI, Ferrocene, plus vitamins A and E (42x and 10x RDA, respectively), group 4 (F...
متن کاملOral iron chelator L1 and autoimmunity.
As Brittenham’ has reviewed in detail, the use of the oral iron chelator LI has been associated with significant clinical and animal toxicity. One of the more controversial issues surrounding the human use of LI has been the possible development of autoimmune phenomena as manifested by development of autoantibodies such as antinuclear antibodies (ANA). The Canadian group investigating LI did no...
متن کاملIron-regulatory proteins, iron-responsive elements and ferritin mRNA translation.
Iron plays a central role in the metabolism of all cells. This is evident by its major contribution to many diverse functions, such as DNA replication, bacterial pathogenicity, photosynthesis, oxidative stress control and cell proliferation. In mammalian systems, control of intracellular iron homeostasis is largely due to posttranscriptional regulation of binding by iron-regulatory RNA-binding ...
