Pulmonary Iron Homeostasis in Hepcidin Knockout Mice
Pulmonary iron excess is deleterious and contributes to a range of chronic and acute inflammatory diseases. Optimal lung iron concentration is maintained through dynamic regulation of iron transport and storage proteins. The iron-regulatory hormone hepcidin is also expressed in the lung. In order to better understand the interactions between iron-associated molecules and the hepcidin-ferroporti...
متن کاملDefective iron homeostasis in beta 2-microglobulin knockout mice recapitulates hereditary hemochromatosis in man
Previously, hepatic iron overload resembling that in hereditary hemachromatosis (HH) has been found in beta 2-microglobulin knockout (beta 2m-/-) mice. We have now characterized iron metabolism in beta 2m-/- mice. The mutant mice fail to limit the transfer of iron from mucosal cells into the plasma. Transferrin saturation is abnormally high. Pathologic iron depositions occur predominantly in li...
متن کاملAssessment of Pancreatic Iron Overload in Transfusion Dependent Thalassemic Patients
Advances in the management of transfusion dependent thalassemic patients have improved the survival of these patients. The most important consequence of repeated and frequent transfusions is iron accumulation in vital organs. The magnetic resonance imaging (MRI) is a non-invasive and valid technique for the estimation of iron stores. Despite multiple studies about cardiac and liver MRI T2*, the...
متن کاملNonrandom association of free iron with membranes of sickle and beta-thalassemic erythrocytes.
To further define the nature of abnormal iron deposits on the membranes of pathologic red blood cells, we have used sickle cell anemia (HbSS), HbSC, and beta-thalassemic erythrocytes (RBCs) to prepare inside-out membranes (IOM) and insoluble membrane aggregates (AGGs) containing coclustered hemichrome and band 3. Study of IOM from HbSC and thalassemic patients showed that amounts of heme iron a...
متن کاملSystemic and Cerebral Iron Homeostasis in Ferritin Knock-Out Mice
Ferritin, a 24-mer heteropolymer of heavy (H) and light (L) subunits, is the main cellular iron storage protein and plays a pivotal role in iron homeostasis by modulating free iron levels thus reducing radical-mediated damage. The H subunit has ferroxidase activity (converting Fe(II) to Fe(III)), while the L subunit promotes iron nucleation and increases ferritin stability. Previous studies on ...
