Ferroportin and Erythroid Cells: An Update
نویسندگان
چکیده
In recent years there have been major advances in our knowledge of the regulation of iron metabolism that have had implications for understanding the pathophysiology of some human disorders like beta-thalassemia and other iron overload diseases. However, little is known about the relationship among ineffective erythropoiesis, the role of iron-regulatory genes, and tissue iron distribution in beta-thalassemia. The principal aim of this paper is an update about the role of Ferroportin during human normal and pathological erythroid differentiation. Particular attention will be given to beta-thalassemia and other diseases with iron overload. Recent discoveries indicate that there is a potential for therapeutic intervention in beta-thalassemia by means of manipulating iron metabolism.

A ferroportin transcript that lacks an iron-responsive element enables duodenal and erythroid precursor cells to evade translational repression.
Ferroportin (FPN1), the sole characterized mammalian iron exporter, has an iron-responsive element (IRE) in its 5' untranslated region, which ensures that its translation is repressed by iron regulatory proteins (IRPs) in iron-deficient conditions to maintain cellular iron content. However, here we demonstrate that duodenal epithelial and erythroid precursor cells utilize an alternative upstrea...
متن کاملExpression of alternative transcripts of ferroportin-1 during human erythroid differentiation.
BACKGROUND AND OBJECTIVES Ferroportin-1 (FPN1) is expressed in various types of cells that play critical roles in mammalian iron metabolism and appears to act as an iron exporter in these tissues. The aim of this study was to investigate whether erythroid cells possess specific mechanisms for iron export. DESIGN AND METHODS The expression of FPN1 during human erythroid differentiation, the ch...
متن کاملDifferentiation of Mouse Yolk Sac Cells to Erythroid Cells in The Presence of Erythropoietin
Purpose: Yolk sac hematopoietic stem cells (YS-HSC) have two dominant characteristices: a larger reproductive capacity and the absence of the expression of MHC associated antigens. Therefore, these cells are promising candidates for transplantation, cell therapy and gene manipulation. There are controversial reports on the effects of erythropoietin (EPO) on the differentiation of yolk sac cells...
متن کاملGlutaredoxin 5 deficiency causes sideroblastic anemia by specifically impairing heme biosynthesis and depleting cytosolic iron in human erythroblasts.
Glutaredoxin 5 (GLRX5) deficiency has previously been identified as a cause of anemia in a zebrafish model and of sideroblastic anemia in a human patient. Here we report that GLRX5 is essential for iron-sulfur cluster biosynthesis and the maintenance of normal mitochondrial and cytosolic iron homeostasis in human cells. GLRX5, a mitochondrial protein that is highly expressed in erythroid cells,...
