Apoptotic Cells Can Induce Compensatory Cell Proliferation through the JNK and the Wingless Signaling Pathways

Abstract

In many metazoans, damaged and potentially dangerous cells are rapidly eliminated by apoptosis. In Drosophila, this is often compensated for by extraproliferation of neighboring cells, which allows the organism to tolerate considerable cell death without compromising development and body size. Despite its importance, the mechanistic basis of such compensatory proliferation remains poorly understood. Here, we show that apoptotic cells express the secretory factors wingless (wg) and decapentaplegic (dpp). When cells undergoing apoptosis were kept alive with the caspase inhibitor p35, excessive nonautonomous cell proliferation was observed. Significantly, wg signaling is necessary and, at least in some cells, also sufficient for mitogenesis under these conditions. Finally, we provide evidence that the DIAP1 antagonists reaper and hid can activate the JNK pathway and that this pathway is required for inducing wg and cell proliferation. These findings support a model where apoptotic cells activate signaling cascades for compensatory proliferation.

  • Wg is induced in a JNK-dependent manner during regenerative growth, tumourigenesis, and compensatory proliferation.

    “Both Yki/YAP and JNK are linked to Wg signalling, as Wg is induced in a JNK-dependent manner during regenerative growth, tumourigenesis, and compensatory proliferation (41,61,62), and interacts with Yki and the Hippo pathway during organ development and tumourigenesis (63-65).”

    Figure 6 and the accompanying results show that blocking JNK prevents Wg induction in the paper’s apoptotic-cell model of compensatory proliferation (page not provided). The copy does not establish the same JNK-dependent Wg induction during regenerative growth or tumourigenesis; the Abstract proposes only that mitogenic signals from apoptotic cells may contribute to tumour growth.

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.
