Metabolic reprogramming and cancer progression

Open access
Faubert, Brandon, Solmonson, Ashley, DeBerardinis, Ralph J.·2020·Science

Abstract

Metabolism as cancer progresses: Numerous cancer-specific alterations in metabolism have been identified but have not yet resulted in an effective anti cancer therapeutic. In a Review, Faubert et al. discuss how metabolism changes as cancer develops from a small, premalignant lesion to an aggressive primary tumor and then metastasizes. Metabolic vulnerabilities likely change with cancer progression, making the identification of general cancer-associated metabolic features difficult. The authors propose that a more targeted approach to tissues and vulnerabilities identified in patients may be more effective. Science , this issue p. eaaw5473

  • Loss of LKB1 sustains KRAS-mediated proliferation through autophagy and increased synthesis of essential macromolecules under nutrient deprivation.

    “This could be explained by the fact that loss of LKB1 sustains KRAS-mediated proliferation through autophagy and increased synthesis of essential macromolecules, even under nutrient-deprived conditions68.”
  • The two hallmarks exhibit commonalities but also differences or antagonisms between aging-associated deregulated nutrient sensing and cancer-associated deregulation of cellular energy metabolism.

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.

Claims read by deepseek-v4.1-flash under definition version 3 (extract-v3) on 2026-10-06.

Classified by jev-1.13-20260917 (gold-guideline-v0.2) on 2026-10-06.

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.
