Mutations in the iron exporter ferroportin (Fpn) (IREG1, SLC40A1, and MTP1) result in hemochromatosis type IV, a disorder with a dominant genetic pattern of inheritance and heterogeneous clinical presentation. Most patients develop iron loading of Kupffer cells with relatively low saturation of plasma transferrin, but others present with high transferrin saturation and iron-loaded hepatocytes. ...

States of chronic inflammation such as inflammatory bowel disease are often associated with dysregulated iron metabolism and the consequent development of an anemia that is caused by maldistribution of iron. Abnormally elevated expression of the hormone hepcidin, the central regulator of systemic iron homeostasis, has been implicated in these abnormalities. However, the mechanisms that regulate...

Among various micro-nutrients, iron plays a major role not only for hemoglobin alone but also for oxidative metabolism and energy production. Hemoglobin functions as a chief oxygen carrier while other iron containing mitochondrial enzymes and respiratory chain proteins are involved in oxidative metabolism and release of energy from carbohydrates and fats. Iron salts have very low bioavailabilit...

High levels of alcohol (ethanol) exposure during fetal life can affect liver development and can increase susceptibility to infection after birth. Our aim was to determine the effects of a moderate level of ethanol exposure in late gestation on the morphology, iron status, and inflammatory status of the ovine fetal liver. Pregnant ewes were chronically catheterized at 91 days of gestation (DG; ...
