Redox regulation of the hypoxia-inducible factor

Pouysségur, Jacques, Mechta-Grigoriou, Fatima·2006·Biological Chemistry

Abstract

Reactive oxygen species (ROS) have long been considered only as cyto- and genotoxic. However, there is now compelling evidence that ROS also act as second messengers in response to various stimuli, such as growth factors, hormones and cytokines. The hypoxia-inducible transcription factor (HIF) is a master regulator of oxygen-sensitive gene expression. More recently, HIF has also been shown to respond to non-hypoxic stimuli. Interestingly, recent reports indicate that ROS regulate HIF stability and transcriptional activity in well-oxygenated cells, as well as under hypoxic conditions. Consequently, ROS appear to be key players in regulating HIF-dependent pathways under both normal and pathological circumstances. This review summarizes the current understanding of the role of ROS in the regulation of the mammalian HIF system.

  • HIF regulation by ROS is graded and redox-window-dependent, explaining how HIF signaling can be engaged under mild hypoxia or near-normoxic conditions in metabolically active or oncogenically transformed cells, rather than exhibiting a binary oxygen response.

    “Importantly, this regulation is graded and redox-window–dependent, explaining how HIF signaling can be engaged under mild hypoxia or even near-normoxic conditions in metabolically active or oncogenically transformed cells, rather than exhibiting a binary oxygen response [[201], [202], [203], [204]].”

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.
