Abstract

Ferroptosis is a form of regulated cell death that is dependent on iron and reactive oxygen species (ROS) and is characterized by lipid peroxidation. It is morphologically and biochemically distinct and disparate from other processes of cell death. As ferroptosis is induced by inhibition of cysteine uptake or inactivation of the lipid repair enzyme glutathione peroxidase 4 (GPX4), the process is favored by chemical or mutational inhibition of the cystine/glutamate antiporter and culminates in the accumulation of reactive oxygen species (ROS) in the form of lipid hydroperoxides. Excessive lipid peroxidation leads to death by ferroptosis and the phenotype is accentuated respectively by the repletion and depletion of iron and glutathione in cells. Furthermore, oxidized phosphatidylethanolamines (PE) harbouring arachidonoyl (AA) and adrenoyl moieties (AdA) have been shown as proximate executioners of ferroptosis. Induction of ferroptosis due to cysteine depletion leads to the degradation of ferritin (i.e. ferritinophagy), which releases iron via the NCOA4-mediated autophagy pathway. Evidence of the manifestation of ferroptosis in vivo in iron overload mice mutants is emerging. Thus, a concerted synchronization of iron availability, ROS generation, glutamate excess and cysteine deficit leads to ferroptosis. A number of questions on the molecular mechanisms of some features of ferroptosis are highlighted as subjects for future investigations.

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?

  • The toxicity of high extracellular glutamate may depend at least in part on activation of ferroptosis through cysteine imbalance.

    “the toxicity of high extracellular glutamate may depend (at least in part) on the activation of ferroptosis through cysteine imbalance [534, 538, 552].”
  • If at the cellular level ROS production exceeds the cell's scavenging ability, lipid peroxidation and DNA damage can lead to cell death via ferroptosis.

    “Furthermore, if at the cellular level ROS production exceeds the cell's scavenging ability, lipid peroxidation and DNA damage can lead to cell death, via a process known as ferroptosis [116].”

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.
