Mitochondrial ROS regulation of proliferating cells

Diebold, Lauren, Chandel, Navdeep S.·2016·Free Radical Biology and Medicine

Abstract

Once thought of exclusively as damaging molecules, reactive oxygen species (ROS) are becoming increasingly appreciated for the role they play in cellular signaling through redox biology. Notably, mitochondria are a major source of ROS within a cell (mROS). Mounting evidence now clearly shows that mROS are critical for intracellular redox signaling by which they contribute to a plethora of cellular processes such as proliferation. mROS are essential for physiological cell proliferation, particularly by the regulation of hypoxia inducible factors (HIFs) under hypoxia. mROS are also vital mediators of growth factor signaling cascades such as angiotensin II (Ang II) and T-cell receptor (TCR) signaling. Pathological proliferative diseases such as cancer utilize mROS to their advantage, aberrantly activating growth factor signaling cascades and perpetuating angiogenesis under hypoxia. This review discusses how mROS positively regulate mitogenic cellular signaling through redox biology, which is critical for both physiological and pathological proliferation.

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?

  • Mitochondrial ROS have been implicated in pathways leading to cell proliferation and senescence and in activation of JNK and NF-κB.

    “Additionally, mitochondrial ROS have been implicated in pathways leading to cell proliferation and senescence (233, 1046) as well as in the activation of other major cell signaling molecules such as the MAP kinase JNK and NF-κB (330, 689).”

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.
