Abstract

Programmed cell death (apoptosis) is a homeostasis program of animal tissues designed to remove cells that are unwanted or are damaged by physiological insults. To assess the functional role of apoptosis, we have studied the consequences of subjecting Drosophila epithelial cells defective in apoptosis to stress or genetic perturbations that normally cause massive cell death. We find that many of those cells acquire persistent activity of the JNK pathway, which drives them into senescent status, characterized by arrest of cell division, cell hypertrophy, Senescent Associated ß-gal activity (SA-ß-gal), reactive oxygen species (ROS) production, Senescent Associated Secretory Phenotype (SASP) and migratory behaviour. We have identified two classes of senescent cells in the wing disc: 1) those that localize to the appendage part of the disc, express the upd, wg and dpp signalling genes and generate tumour overgrowths, and 2) those located in the thoracic region do not express wg and dpp nor they induce tumour overgrowths. Whether to become tumorigenic or non-tumorigenic depends on the original identity of the cell prior to the transformation. We also find that the p53 gene contributes to senescence by enhancing the activity of JNK.

  • Elimination of scrib- cells by cell competition involves JNK-dependent suppression of Yki activity.

    “In contrast, elimination of scrib -cells by cell competition involved JNK-dependent suppression of Yki activity (12,30,36-38).”

    From A Tumour-Specific Molecular Network Promotes Tumour Growth in <i>Drosophila</i> by Enforcing a JNK-YKI Feedforward Loop (2023) · cites this paper as [37]

    The Introduction describes JNK-dependent cell killing after irradiation, and the Results examine JNK activity in apoptosis-deficient cells. Neither passage addresses elimination of scrib mutant cells by cell competition or suppression of Yki activity. Searches for “scrib,” “Yki,” and related phrasing found no passage in our copy supporting that mechanism. (LLM, conf=0.75)

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.
