General description

Ammonium iron(III)citrate can be used as a reagent and iron precursor in several organic reactions and Fe3O4-based nanomaterial preparation. It can be prepared by treating Fe(OH)3 with citric acid and NH4OH in various ratios.

Application

Ammonium iron(III) citrate can be used as a reagent to prepare amphiphilic siderophore iron acinetoferrin complex from acinetoferrin in the presence of HEPES (4-(2-hydroxyethyl)-1-piperazineethanesulfonic acid) buffer. It can also be used as an iron precursor to prepare Fe3O4-carbon dots magnetic-fluorescent hybrid nanoparticles.

Hepcidin regulates systemic iron homeostasis. Suppression of hepcidin expression occurs physiologically in iron deficiency and increased erythropoiesis but is pathologic in thalassemia and hemochromatosis. Here we show that epigenetic events govern hepcidin expression. Erythropoiesis and iron deficiency suppress hepcidin via

Cytosolic ferritins sequester and store iron, consequently protecting cells against iron-mediated free radical damage. However, the mechanisms of iron exit from the ferritin cage and reutilization are largely unknown. In a previous study, we found that mitochondrial ferritin (MtFt) expression
