Abstract

Iron is essential for many biological processes, including oxygen delivery, and its supply is tightly regulated. Hepcidin, a small peptide synthesized in the liver, is a key regulator of iron absorption and homeostasis in mammals. Hepcidin production is increased by iron overload and decreased by anemia and hypoxia; but the molecular mechanisms that govern the hepcidin response to these stimuli are not known. Here we establish that the von Hippel-Lindau/hypoxia-inducible transcription factor (VHL/HIF) pathway is an essential link between iron homeostasis and hepcidin regulation in vivo. Through coordinate downregulation of hepcidin and upregulation of erythropoietin and ferroportin, the VHL-HIF pathway mobilizes iron to support erythrocyte production.

  • HIF effects (via hepcidin) mobilisation of iron and can cause expression of inflammatory cytokines such as IL-1, IL-6 and TNF-α under hypoxia, and consequently increases sepsis (HIF-knockout mice are resistant to LPS-induced sepsis).

    “In particular, HIF effects (via hepcidin) the mobilisation or iron and can cause the expression of inflammatory cytokines such as IL-1, IL-6 and TNF-α [2254-2256] under conditions (hypoxia) where superoxide and peroxide production are likely to be increased, and consequently increases sepsis (in that HIF-knockout mice are resistant to LPS-induced sepsis [2254,2255]).”
  • Hypoxia-induced proteins HIF-1 or PDGF-BB reduce hepcidin expression, enhancing iron delivery for erythropoiesis.

    “and several proteins induced by hypoxia such as hypoxia inducible factor-1 (HIF-1) or platelet derived growth factor BB (PDGF-BB) reduce hepcidin expression, thereby enhancing iron delivery for erythropoiesis (Peyssonnaux et al., 2007; Sonnweber et al., 2014).”

  • The von Hippel-Lindau/hypoxia-inducible transcription factor (HIF) system also appears to control hepcidin expression, with HIF1α acting as a repressor when it binds to the hepcidin promoter.

    “The von Hippel-Lindau/hypoxia-inducible transcription factor (HIF) system also appears to control hepcidin expression, with HIF1␣ acting as a repressor when it binds to the hepcidin promoter.109”

    From Forging a field: the golden age of iron biology. (2008) · cites this paper as [109]

  • Experimental studies in cultured cells, animal models and human subjects have established that hepcidin production is O2-sensitive and involves the HIF pathway.

    “Experimental studies in cultured cells, in animal models and in human subjects have established that hepcidin production is O2-sensitive and involves the HIF pathway.”

  • Nrf2 and AP1 family transcription factors, in conjunction with p300/CBP, are involved in activation of the ARE.

    “Subsequent investigation revealed that Nrf2 and AP1 family transcription factors, in conjunction with transcriptional coactivator p300/CBP, are involved in the activation of the ARE (246, 302, 306, 307)”

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.
