Abstract

Oxygen sensing revisited: The cellular response to hypoxia (oxygen deficiency) is a contributing factor in many human diseases. Previous studies examining the way in which hypoxia alters gene expression have focused on oxygen-sensing enzymes that regulate the activity of a transcription factor called hypoxia-inducible factor (see the Perspective by Gallipoli and Huntly). Chakraborty et al. and Batie et al. now show that hypoxia can also affect gene expression through direct effects on chromatin regulators. Certain histone demethylases, such as KDM6A and KDM5A, were found to be direct sensors of oxygen. In cell-culture models, hypoxia diminished the activity of these enzymes and caused changes in the expression of genes that govern cell fate.

  • Hypoxia directly modulates the enzymatic activity of histone demethylases independently of HIF, with implications for cancer metabolism.

    “Hypoxia has been found to directly modulate the enzymatic activity of histone demethylases independently of HIF, with important implications for the control of metabolism in cancers.”

    From HIF-1-Independent Mechanisms Regulating Metabolic Adaptation in Hypoxic Cancer Cells (2021) · cites this paper as [110]

    The paper’s Abstract reports that hypoxia promotes histone methylation independently of HIF and identifies KDM6A as an oxygen-sensitive histone demethylase. It also discusses effects on cell differentiation and malignant transformation, including findings in cancer cells and tumors, but does not establish an effect on the control of metabolism in cancers. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • Rapid histone hypermethylation during hypoxia occurs independently of HIF-1 and of other known hypoxia-inducible inhibitors of KDM activity such as reactive oxygen species and 2-hydroxyglutarate.

    “These rapid histone hypermethylations occurred independently of HIF-1 and of other known hypoxia-inducible inhibitors of KDM activity, such as reactive oxygen species and 2-hydroxyglutarate [110,111].”

    From HIF-1-Independent Mechanisms Regulating Metabolic Adaptation in Hypoxic Cancer Cells (2021) · cites this paper as [110]

    The passage labeled Abstract (page unavailable) reports hypoxia-induced histone hypermethylation in cells unable to mount a HIF response. It also concludes that increased 2-hydroxyglutarate and reactive oxygen species did not explain the effect. The passages do not establish the claimed rapid timing. (LLM, conf=0.84)

    Experimental — accuracy not yet measured
  • KDM5A and KDM6A are oxygen sensors that become inactivated during hypoxia, causing rapid histone hypermethylation.

    “Two members of the Jumonji domain KDM enzymes, KDM5A and KDM 6A, were recently implicated as oxygen sensors that become inactivated during hypoxia, causing rapid histone hypermethylation [110,111].”

    From HIF-1-Independent Mechanisms Regulating Metabolic Adaptation in Hypoxic Cancer Cells (2021) · cites this paper as [110]

    In the paper’s main text (indexed as Abstract; page unavailable), the authors report low oxygen affinity for KDM5A and KDM6A and hypoxia-induced histone hypermethylation. They identify KDM6A as an oxygen sensor and argue that KDM5A likely plays a similar role. The passages establish the effect but do not establish the claim’s qualifier that hypermethylation occurs rapidly. (LLM, conf=0.84)

    Experimental — accuracy not yet measured
  • Histone demethylases KDM5A and KDM6A sense oxygen concentrations and modulate H3K4me3 and H3K27me3 levels.

    “The recent discovery that histone demethylases KDM5A and KDM6A (also known as UTX) can sense oxygen concentrations and thereby modulate H3K4me3 and H3K27me3 levels 91,92 is a first step in this direction.”

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.
