Abstract

Entosis is a mechanism of cell death that involves neighbor cell ingestion. This process occurs in cancers and promotes a form of cell competition, where winner cells engulf and kill losers. Entosis is driven by a mechanical differential that allows softer cells to eliminate stiffer cells. While this process can be induced by matrix detachment, whether other stressors can activate entosis is unknown. Here, we find that entosis is induced in adherent cells by glucose withdrawal. Glucose withdrawal leads to a bimodal distribution of cells based on their deformability, where stiffer cells appear in a manner requiring the energy-sensing AMP-activated protein kinase (AMPK). We show that loser cells with high levels of AMPK activity are eliminated by winners through entosis, which supports winner cell proliferation under nutrient-deprived conditions. Our findings demonstrate that entosis serves as a cellular response to metabolic stress that enables nutrient recovery through neighbor cell ingestion.

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?

  • Entosis can be triggered by differences in mechanical properties or responses to metabolic stress of cancer cells competing for proliferation.

    “differences in the mechanical properties [696] or responses to metabolic stress [697] of cancer cells competing for proliferation.”
  • In glucose withdrawal, cells with high AMPK activity succumb to entosis, suggesting a possible function of entosis for nutrient recovery by cells with lower AMPK activity.

    “in conditions of glucose withdrawal, cells displaying high 5′ AMP-activated protein kinase (AMPK) activity succumb to entosis, underscoring a possible function of this process for nutrient recovery by cells with comparatively lower AMPK activity (which a priori are metabolically fitter) [697].”

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.
