Abstract

Iron is an essential element in all living organisms and is required as a cofactor for oxygen-binding proteins. Iron metabolism, oxygen homeostasis and erythropoiesis are consequently strongly interconnected. Iron needs to be tightly regulated, as iron insufficiency induces a hypoferric anemia in mammals, coupled to hypoxia in tissues, whereas excess iron is toxic, and causes generation of free radicals. Given the links between oxygen transport and iron metabolism, associations between the physiology of hypoxic response, and the control of iron availability are important. Numerous lines of investigation have proven that the HIF transcription factors function as central mediators of cellular adaptation to critically low oxygen levels in both normal and compromised tissues. Several of these target genes are involved in iron homeostasis, reflecting the molecular links between oxygen homeostasis and iron metabolism.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • 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]).”

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.
