TLDR
Iron has the capacity to accept and donate electrons readily, interconverting between ferric (Fe2+) and ferrous (Fe3+) forms, which makes it a useful component of cytochromes, oxygen-binding molecules, and many enzymes.Abstract:

Bacterial heme sources: the role of heme, hemoprotein receptors and hemophores.
TL;DR: The major mechanisms by which Gram-negative bacteria acquire heme from host heme-carrier proteins involve either direct binding to specific outer membrane receptors or release of bacterial hemophores that take up heme and shuttle it back to specific receptors.
Journal ArticleDOI
An update on iron physiology
TL;DR: In chronic inflammation, the excess of hepcidin decreases iron absorption and prevents iron recycling, which results in hypoferremia and iron-restricted erythropoiesis, despite normal iron stores (functional ID), and anemia of chronic disease (ACD), which can evolve to ACD plus true ID (ACC + ID).

8-Hydroxyquinolines: a review of their metal chelating properties and medicinal applications
TL;DR: Diverse bioactivities of 8HQ and newly synthesized 8HQ-based compounds are discussed together with their mechanisms of actions and structure–activity relationships.
Journal ArticleDOI
Greater prevalence of iron deficiency in overweight and obese children and adolescents
TL;DR: Insufficient dietary intake of iron, whether absolute or relative to body mass, and increased iron needs may be a result of unbalanced nutrition or repeated short-term restrictive diets.

Regulatory defects in liver and intestine implicate abnormal hepcidin and Cybrd1 expression in mouse hemochromatosis.

TL;DR: It is proposed that inappropriate regulatory cues from the liver underlie greater duodenal iron absorption, possibly involving the ferric reductase Cybrd1.

TL;DR: Using linkage-disequilibrium and full haplotype analysis, this paper identified a 250-kilobase region more than 3 megabases telomeric of the major histocompatibility complex (MHC) that is identical-by-descent in 85% of patient chromosomes.

A novel MHC class-I-like gene is mutated in patients with hereditary haemochromatosis
TL;DR: Using linkage–disequilibrium and full haplotype analysis, a region more than 3 megabases telomeric of the major histocompatibility complex (MHC) that is identical–by–descent in 85% of patient chromosomes is identified, containing a gene related to the MHC class I family, termed HLA–H, containing two missense alterations.

TL;DR: A new metal-ion transporter in the rat, DCT1, which has an unusually broad substrate range that includes Fe2+, Zn2+, Mn2+, Co2+, Cd2+, Cu2+, Ni2+ and Pb2+.

Prevalence of Iron Deficiency in the United States
TL;DR: Iron deficiency and iron deficiency anemia are still relatively common in toddlers, adolescent girls, and women of childbearing age and were more likely in those who are minority, low income, and multiparous.

Microcytic anaemia mice have a mutation in Nramp2, a candidate iron transporter gene.
Joseph V. Gray,Keith J. Johnson +1 more
TL;DR: A positional cloning strategy is undertaken to identify the causative mutation in mice with microcytic anaemia, and it is suggested that the phenotype is a consequence of a missense mutation in Nramp2 (ref. 5), a previously identified gene of unknown function.
