Abstract

Physiological hypoxia results in a host of responses that include increased ventilation, constriction of the pulmonary artery, and a cellular transcriptional program that promotes glycolysis, angiogenesis, and erythropoiesis. Mitochondria are the primary consumers of cellular oxygen and have thus been speculated for years to be the site of cellular oxygen sensing. Many of the cellular responses to hypoxia are now known to be mediated by the production of reactive oxygen species at mitochondrial complex III. While the mechanism by which cytosolic oxidant concentration is increased during hypoxia is unknown, the importance of the maintenance of cellular oxygen supply requires further investigation into the role of ROS as hypoxia signaling molecules. The following is a brief overview of the current understanding of the role of mitochondrial-produced ROS in cellular oxygen signaling.

  • HIFs both sense and remodel intracellular ROS levels through effects on mitochondrial activity, antioxidant pathways, and metabolic flux.

    “These functions are intimately coupled to redox regulation, as HIFs both sense and remodel intracellular ROS levels through effects on mitochondrial activity, antioxidant pathways, and metabolic flux [252,253].”

    From HIF inhibition: Current strategies and clinical challenges (2026) · cites this paper as [252]

    The section “Mitochondrial ROS are required for hypoxic activation of HIFs” reports that mitochondrial ROS help stabilize HIF-1α, supporting the ROS-to-HIF direction of the claim. The passages do not establish the reverse claim that HIFs remodel intracellular ROS through mitochondrial activity, antioxidant pathways, or metabolic flux. Page numbers are not provided in our copy.

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.
