Abstract

Autophagy is a critical cellular process that generally protects cells and organisms from stressors such as nutrient deprivation. In addition to its role in normal physiology, autophagy plays a role in pathological processes such as cancer. Indeed, there has been substantial work exploring the complex and context-dependent role of autophagy in cancer. One of the emerging themes is that in certain cancer types, autophagy is important to support tumor growth; therefore, inhibiting autophagy as a therapeutic approach is actively being tested in clinical trials. A key mechanism of how autophagy promotes the growth and survival of various cancers is its ability to support cellular metabolism. The diverse metabolic fuel sources that can be produced by autophagy provide tumors with metabolic plasticity and can allow them to thrive in what can be an austere microenvironment. Therefore, understanding how autophagy can fuel cellular metabolism will enable more effective combinatorial therapeutic strategies.

  • When cancer cells face metabolic stress, autophagy functions as a survival mechanism.

    “Autophagy is upregulated in KRAS mutant cancer cells and it serves as a cell survival mechanism when cancer cells experience metabolic stress (97).”

  • KRAS-mutant cancer cells show increased autophagy.

    “Autophagy is upregulated in KRAS mutant cancer cells and it serves as a cell survival mechanism when cancer cells experience metabolic stress (97).”

  • Once a potentially tumorigenic clone has emerged, autophagy must be reactivated to improve cellular fitness and facilitate transition to full-blown malignancy.

    “According to a recurrent scenario, once a potentially tumorigenic clone has emerged, autophagy must be (re)activated to improve cellular fitness and to facilitate the transition to full-blown malignancy.164”

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.
