The craniofacial phenotype associates with decreased chondrocyte size and increased neural crest cell death. We found that autophagy is elevated in raptor mutants. Chemical inhibition...

Because there was no accompanying increase in cell death ( Zhang et al., 2008 ), cell proliferation and not cell survival likely explains why young male rats have...

... were caused by JNK-mediated cell death in the wing pouch via Eiger/TNF signaling. The JNK activation in M /+, yki /+ wing discs required the caspase Dronc, which is normally blocked by DIAP1. Notably, heterozygosity of yki reduced DIAP1 expression in the wing pouch, leading to elevation of Dronc...

In Arabidopsis , final seed size is determined by early expansion of the coenocytic endosperm, which then cellularises and subsequently undergoes developmental programmed cell death, breaking down as the embryo grows. Endosperm breakdown requires the endosperm...

Overexpression of Draper or the JNK pathway in follicle cells is sufficient to induce death of the underlying germline, suggesting that there is coordination between the germline and follicular epithelium to promote germline cell death.
