Drosophila Caspase DRONC Is Required for Specific Developmental Cell Death Pathways and Stress-Induced Apoptosis

Abstract

Proteases of the caspase family play key roles in the execution of apoptosis. In Drosophila there are seven caspases, but their roles in cell death have not been studied in detail due to a lack of availability of specific mutants. Here, we describe the generation of a specific mutant of the Drosophila gene encoding DRONC, the only caspase recruitment domain (CARD) containing apical caspase in the fly. dronc mutants are pupal lethal and our studies show that DRONC is required for many forms of developmental cell deaths and apoptosis induced by DNA damage. Furthermore, we demonstrate that DRONC is required for the autophagic death of larval salivary glands during metamorphosis, but not for histolysis of larval midguts. Our results indicate that DRONC is involved in specific developmental cell death pathways and that in some tissues, effector caspase activation and cell death can occur independently of DRONC.

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.
