Abstract

Reactive oxygen species (ROS) are generated during mitochondrial oxidative metabolism as well as in cellular response to xenobiotics, cytokines, and bacterial invasion. Oxidative stress refers to the imbalance due to excess ROS or oxidants over the capability of the cell to mount an effective antioxidant response. Oxidative stress results in macromolecular damage and is implicated in various disease states such as atherosclerosis, diabetes, cancer, neurodegeneration, and aging. Paradoxically, accumulating evidence indicates that ROS also serve as critical signaling molecules in cell proliferation and survival. While there is a large body of research demonstrating the general effect of oxidative stress on signaling pathways, less is known about the initial and direct regulation of signaling molecules by ROS, or what we term the "oxidative interface." Cellular ROS sensing and metabolism are tightly regulated by a variety of proteins involved in the redox (reduction/oxidation) mechanism. This review focuses on the molecular mechanisms through which ROS directly interact with critical signaling molecules to initiate signaling in a broad variety of cellular processes, such as proliferation and survival (MAP kinases, PI3 kinase, PTEN, and protein tyrosine phosphatases), ROS homeostasis and antioxidant gene regulation (thioredoxin, peroxiredoxin, Ref-1, and Nrf-2), mitochondrial oxidative stress, apoptosis, and aging (p66Shc), iron homeostasis through iron-sulfur cluster proteins (IRE-IRP), and ATM-regulated DNA damage response.

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

  • ROS interacting with proteins impact several signaling pathways involved in the control of cell proliferation and apoptosis.

    “By interacting with proteins, ROS have an impact on several signaling pathways involved in the control of cell proliferation and apoptosis.”

    From ROS in cancer therapy: the bright side of the moon (2020) · cites this paper as [8]

  • ROS induces cell death, cell senescence, repair failure, inhibition of cell proliferation, and cell cycle arrest.

    “Furthermore, ROS induces cell death11, cell senescence, repair failure12, inhibition of cell proliferation, and cell cycle arrest13.”

    From Key points for the development of antioxidant cocktails to prevent cellular stress and damage caused by reactive oxygen species (ROS) during manned space missions (2021) · cites this paper as [11]

    Citation 12 is attached to the claim about cell senescence and repair failure. Section 5 discusses ROS and aging, while section 7 discusses oxidative stress and DNA-repair signaling; neither states that ROS induces cellular senescence or repair failure. Searches for those terms found no passage establishing either outcome. (LLM, conf=0.72)

  • In response to increased levels of ROS, PKC is activated, which in turn can activate NOXs.

    “In response to the increased levels of ROS, the PKC is activated, which in turn, can activate NOXs (319, 776).”
  • Redox dysregulation can affect cell proliferation and differentiation, energy metabolism, and neurotransmission through altered redox-sensitive protein function, redox-dependent gene expression, and epigenetic mechanisms.

    “A redox dysregulation can affect cell proliferation/differentiation, energy metabolism, and neurotransmission via an alteration of redox-sensitive protein function, redox-dependent gene expression, and epigenetic mechanisms (Cyr and Domann, 2011; Ray et al., 2012; Valko et al., 2007).”

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.
