A Liver Hepcidin-Intestinal HIF-2α Axis Regulates Iron Absorption During Systemic Iron Deficiency, Hypoxia and Hemochromatosis
Ontology highlight
ABSTRACT: Iron-related disorders are among the most prevalent diseases worldwide. Systemic iron homeostasis requires hepcidin (Hamp), a hepatic-derived hormone that controls iron mobilization through its molecular target, ferroportin (FPN), the only known mammalian iron exporter. Here, we took a transcriptomic approach to to compare the duodenal transcriptome during systemic iron demand to that of hepcidin-deficiency iron overload. Hampfl/fl (control) and AlbCreERT2;Hampfl/fl mice were placed on iron-replete and low-iron diets and were sacrificed two weeks following tamoxifen treatment. Duodenum RNA expression was compared across genotypes and across iron-replete and low iron diets.
