Abstract

Summary Death of all the cancer cells in a tumor is the ultimate goal of cancer therapy. Therefore much of the current effort in cancer research is focused on activating cellular machinery that facilitates cell death such as factors involved in causing apoptosis. However, recently a number of studies point to some counter-intuitive roles for apoptotic caspases in radiation therapy as well as in tissue regeneration. It appears that a major function of apoptotic caspases is to facilitate tissue regeneration and tumor cell repopulation during cancer therapy. Because tumor cell repopulation has been shown to be important for local tumor relapse, understanding the molecular mechanisms behind tumor repopulation will be important to enhance cancer radiotherapy. In this review, we discuss our current knowledge of these potentially paradigm-changing phenomena and mechanisms in various organisms and their implications on the development of novel cancer therapeutics and strategies.

  • Mild caspase induction promotes tumour growth.

    “In addition, misregulation of the Hippo, JNK or Wg pathway is also linked to activation of caspases mediated apoptosis, and recently mild caspase induction was shown to promote tumour growth (66,67).”

    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 [66]

    The section “Cell death stimulated tumor repopulation during radiotherapy” reports that caspase-3 activity in irradiated, dying feeder cells promotes tumor-cell proliferation. The Summary also describes low-to-moderate caspase activation in some tumors, but does not show that mild caspase induction itself promotes tumor growth. (LLM, conf=0.84)

    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 [66]

    The sections “Cell death: the current paradigm” and “Compensatory proliferation, cell death induced tissue regeneration in lower organisms” describe caspase activation in apoptosis and link apoptotic cells to Wingless signaling; the paper also discusses JNK in compensatory proliferation. They do not say that misregulation of Hippo, JNK, or Wg activates caspase-mediated apoptosis, and the cited passages do not address Hippo. (LLM, conf=0.84)

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.
