Abstract

Although historically viewed as purely harmful, recent evidence suggests that reactive oxygen species (ROS) function as important physiological regulators of intracellular signaling pathways. The specific effects of ROS are modulated in large part through the covalent modification of specific cysteine residues found within redox-sensitive target proteins. Oxidation of these specific and reactive cysteine residues in turn can lead to the reversible modification of enzymatic activity. Emerging evidence suggests that ROS regulate diverse physiological parameters ranging from the response to growth factor stimulation to the generation of the inflammatory response, and that dysregulated ROS signaling may contribute to a host of human diseases.

  • High levels of ROS generated by ongoing aerobic glycolysis followed by pyruvate oxidation in mitochondria (the Warburg effect) increase receptor and oncogene activity and induce genetic instability.

    “high levels of ROS generated by ongoing aerobic glycolysis followed by pyruvate oxidation in mitochondria (the Warburg effect), increase receptor and oncogene activity, and the stimulation of growth factor-dependent pathways or oxidizing enzymes induce genetic instability3,4.”

    From ROS in cancer therapy: the bright side of the moon (2020) · cites this paper as [4]

    In “Oxidants and their cellular targets” (page unavailable), the paper says mitochondria produce ROS during aerobic respiration and that ROS are involved in growth-factor signaling. It does not link those effects to the claimed Warburg-effect sequence, establish increased oncogene activity, or say that these pathways induce genetic instability. (LLM, conf=0.87)

  • Generation of superoxide and hydrogen peroxide mediates critical processes such as angiogenesis, hypoxic adaptation, and energy homeostasis.

    “Indeed, the generation of superoxide and hydrogen peroxide, among others, has been shown to mediate critical processes such as angiogenesis, hypoxic adaptation, and energy homeostasis (96, 249, 291, 720, 778, 825, 960).”
  • ROS have origin from two main sources: mitochondrial oxidative metabolism and processes of cellular response to xenobiotics, bacteria, and cytokines during which ROS are formed as part of signal transduction or defense.

    “As outlined above, ROS have origin from two main sources: mitochondrial oxidative metabolism and processes of cellular response to xenobiotics, bacteria, and cytokines during which ROS are formed as a part of either signal transduction pathways or a cellular defense mechanism (Finkel 2011).”

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.
