Abstract

Recovery from blood loss requires a greatly enhanced supply of iron to support expanded erythropoiesis. After hemorrhage, suppression of the iron-regulatory hormone hepcidin allows increased iron absorption and mobilization from stores. We identified a new hormone, erythroferrone (ERFE), that mediates hepcidin suppression during stress erythropoiesis. ERFE is produced by erythroblasts in response to erythropoietin. ERFE-deficient mice fail to suppress hepcidin rapidly after hemorrhage and exhibit a delay in recovery from blood loss. ERFE expression is greatly increased in Hbb(th3/+) mice with thalassemia intermedia, where it contributes to the suppression of hepcidin and the systemic iron overload characteristic of this disease.

  • In iron-loading anemias, such as β-thalassemia, enhanced albeit ineffective erythropoiesis releases erythroferrone, which sequesters BMP receptor ligands, thereby inhibiting hepcidin.

    “In iron-loading anemias, such as β-thalassemia, enhanced albeit ineffective ery-thropoiesis releases erythroferrone, which sequesters BMP receptor ligands, thereby inhibiting hepcidin.”
  • Erythroferrone (ERFE) is released by erythroid precursors stimulated by erythropoietin to suppress hepcidin expression and favor iron acquisition for hemoglobin synthesis.

    “Erythroferrone (ERFE) is released by erythroid precursors stimulated by erythropoietin to suppress hepcidin expression and favor iron acquisition for hemoglobin synthesis.52”
  • Erythroferrone is produced by erythroblasts in response to erythropoietic stimulation and suppresses hepcidin synthesis, making more iron available for erythropoiesis.

    “Another set of regulatory factors conveys the iron requirements for erythropoiesis and includes the recently identified hormone erythroferrone12, which is produced by erythroblasts in response to erythropoietic stimulation by endogenous or synthetic erythropoietin. Erythroferrone suppresses hepcidin synthesis, making more iron available for enhanced erythropoiesis.”

  • In untransfused patients with β-thalassaemia, blood hepcidin levels are very low despite high iron concentrations and iron deposition, due to suppression by mediators from expanded erythroblasts.

    “Despite high concentrations of iron and deposition of iron in the liver and other vital organs, the blood level of hepcidin in untransfused patients with β-thalassaemia is very low38–40, owing to suppression by mediators originating from the expanded erythroblast population in the bone marrow12,41.”

  • Erythroferrone is produced by EPO-stimulation of erythroid progenitors and blocks hepcidin synthesis in hepatocytes.

    “Erythroferrone (ERFE) is produced by erythropoietin (EPO)-stimulation of erythroid progenitors and blocks hepcidin synthesis in the hepatocytes (Kautz et al., 2014).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
