Mitochondrial ROS Generation and Its Regulation: Mechanisms Involved in H 2 O 2 Signaling

Rigoulet, Michel, Yoboue, Edgar D., Devin, Anne·2011·Antioxidants & Redox Signaling

Abstract

Mitochondria are the main source of reactive oxygen species in the cell. These reactive oxygen species have long been known as being involved in oxidative stress. This is a review of the mechanisms involved in reactive oxygen species generation by the respiratory chain and some of the dehydrogenases and the control by thermodynamic and kinetic constraints. Mitochondrial ROS produced at the level of the bc1 complex as well at the level of complex I are discussed. It was recognized more than a decade ago that they can also function as signaling molecules. This signaling role will be developed both in terms of mechanism and in terms of mitochondrial ROS signaling. The notion that hydrogen peroxide acts not only as a damaging oxidant but also as a signaling molecule was proposed more than a decade ago. Hydrogen peroxide signaling can be either direct (oxidation of its target) or indirect (involving peroxiredoxins, for example). The consequences of ROS signaling on crucial biologic processes such as cell proliferation and differentiation are discussed. Antioxid. Redox Signal. 14, 459—468.

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

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

  • Mitochondria produce reactive oxygen species as a consequence of electron leak during respiration.

    “It is well established that mitochondria produce ROS as a consequence of electron leak during respiration (223, 349).”

    From Redox regulation of mitochondrial function (2012) · cites this paper as [349]

  • There is a threshold range of ROS concentrations beyond which ROS become harmful, although some increases in ROS can stimulate essential pathways.

    “Although some increases in ROS can stimulate these essential pathways, there is a threshold range of concentrations beyond which ROS become harmful (83, 206, 349).”

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.
