IRON METABOLISM Iron overload and chelation
Iron is one of the most common elements in nature. As a transition metal it is very efficient in electron transport and redox reactions. The proteins and enzymes in which iron is an essential component play a key role in respiration, energy production, detoxification of harmful oxygen species and cell replication. Despite the abundance of iron in nature, the solubility of its stable ferric form...
متن کاملTHE RELATIONSHIP BETWEEN ALUMINIUM TOXICITY AND IRON METABOLISM IN RATS
The relationship between aluminium toxicity and iron metabolism was studied. Male rats were exposed to aluminium by daily intraperitoneal injection of 40pmolelkg body weight. After 45 days, aluminium intoxified rats had a significant loweredserum ferritin (55%), iron (42%), TIBC (25%) and hemoglobin(31%). At thesame time the serum ceruloplasmin level was elevated by 60%. This result shows t...
متن کاملIron Status in Newborns Born to Iron-Deficient Mothers
Background: Iron deficiency anemia is one of the important problems during pregnancy. Iron deficiency has several adverse effects on pregnant women and their newborns. Objective: To determine the status of iron store in newborns born to mothers with iron deficiency anemia. Methods: In a cross-sectional study, 90 mothers were categorized into three groups according to their pre-delivery hemoglo...
متن کاملBradyrhizobium japonicum senses iron through the status of haem to regulate iron homeostasis and metabolism
The Irr protein from the bacterium Bradyrhizobium japonicum is expressed under iron limitation to mediate iron control of haem biosynthesis. The regulatory input to Irr is the status of haem and its precursors iron and protoporphyrin at the site of haem synthesis. Here, we show that Irr controls the expression of iron transport genes and many other iron-regulated genes not directly involved in ...
متن کاملHemochromatosis and Iron Metabolism
Hereditary hemochromatosis Hereditary hemochromatosis (HH) is characterized by abnormal iron absorption from the diet resulting in progressive iron overload, causing tissue damage of several organs, particularly the liver (1). Historically HH has been regarded as an extremely rare inborn error of metabolism causing "bronze diabetes", liver cirrhosis and hepatocellular carcinoma due to heavy iro...
