Abstract

Ferroptotic cell death and cancer: Cell death can occur through different mechanisms, several of which are being explored as potential targets for cancer treatment. One form of cell death that has attracted recent interest is ferroptosis, which is triggered by high intracellular levels of lipid reactive oxygen species. Pancreatic cancer cells have high levels of reactive oxygen species but manage to avoid ferroptosis by importing extracellular cysteine. Studying mice bearing pancreatic tumors, Badgley et al. found that administration of a drug inhibiting cysteine import induced tumor-selective ferroptosis and inhibited tumor growth. Further work will be required to determine whether this therapeutic strategy will be effective in human pancreatic cancer, a tumor type for which new treatments are urgently needed.

  • Depletion of CoA contributes to the induction of ferroptosis by erastin.

    “Reflecting on recent reports suggesting that depletion of CoA contributes to the induction of ferroptosis by erastin (25, 26)”

    From Eprenetapopt triggers ferroptosis, inhibits NFS1 cysteine desulfurase, and synergizes with serine and glycine dietary restriction (2022) · cites this paper as [25]

    The passage discussing Fig. 3E–F reports that system xC– inhibition reduced CoA levels and that added CoA prevented ferroptosis induced by imidazole ketone erastin (IKE) in human PDAC cells. This supports a contribution from CoA depletion, but the experiments used IKE rather than erastin itself. (LLM, conf=0.83)

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.
