Abstract

Autophagy is a catabolic process that is negatively regulated by growth and has been implicated in cell death. We find that autophagy is induced following growth arrest and precedes developmental autophagic cell death of Drosophila salivary glands. Maintaining growth by expression of either activated Ras or positive regulators of the class I phosphoinositide 3-kinase (PI3K) pathway inhibits autophagy and blocks salivary gland cell degradation. Developmental degradation of salivary glands is also inhibited in autophagy gene (atg) mutants. Caspases are active in PI3K-expressing and atg mutant salivary glands, and combined inhibition of both autophagy and caspases increases suppression of gland degradation. Further, induction of autophagy is sufficient to induce premature cell death in a caspase-independent manner. Our results provide in vivo evidence that growth arrest, autophagy, and atg genes are required for physiological autophagic cell death and that multiple degradation pathways cooperate in the efficient clearance of cells during development.

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?

  • In a limited number of cases, autophagy has been established as the cause of cell death, although opposite results have been reported using analogous experimental settings.

    “In a limited number of cases, autophagy has been established as the cause of cell death; 97,199,[658][659][660][661][662][663][664] although opposite results have been reported using analogous experimental settings.665”
  • Complete removal of larval salivary glands during D. melanogaster metamorphosis requires both apoptotic and autophagic machinery.

    “Along similar lines, the complete removal of larval salivary glands from D. melanogaster larvae undergoing metamorphosis requires the apoptotic as well as the autophagic machinery [830–832].”
  • In D. melanogaster midgut and salivary gland developmental scenarios, autophagy-dependent cell death is preceded by growth arrest and controlled by ecdysone.

    “In both these developmental scenarios, autophagy-dependent cell death is preceded by growth arrest and is controlled by ecdysone, a steroid hormone that is critically required in Drosophila to undergo the larva-to-pupa transition and subsequent metamorphosis into an adult fly [830, 833].”

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.
