Programmed cell death during Drosophila embryogenesis.
The deliberate and orderly removal of cells by programmed cell death is a common phenomenon during the development of metazoan animals. We have examined the distribution and ultrastructural appearance of cell deaths that occur during embryogenesis in Drosophila melanogaster. A large number of cells die during embryonic development in Drosophila. These cells display ultrastructural features that...
متن کاملThe Role of Caspase 9 during Programmed Cell Death in Ciliary Ganglia of Chick Embryos
During programmed cell death (PCD) apoptosis is controlled by many factors such as proteases. With no specific protease (s) known during PCD in the developing nervous system so far, we sought to determine if any specific protease (s) is involved in this process and therefore used different protease inhibitors during PCD (from embryonic day 6 to 10) in chick embryos. Among the inhibitors commerc...
متن کاملMetacaspase-dependent programmed cell death is essential for plant embryogenesis
In plants, as in animals, programmed cell death (PCD) is a key process responsible for the elimination of unneeded structures and for overall shape remodeling during development [1]; however, the molecular mechanisms remain poorly understood. Despite the absence of canonical caspases in plants, dying plant cells show an increased proteolytic caspase-like activity [2]. Moreover, the cell death c...
متن کاملCysteine protease mcII-Pa executes programmed cell death during plant embryogenesis.
Programmed cell death (PCD) is indispensable for eukaryotic development. In animals, PCD is executed by the caspase family of cysteine proteases. Plants do not have close homologues of caspases but possess a phylogenetically distant family of cysteine proteases named metacaspases. The cellular function of metacaspases in PCD is unknown. Here we show that during plant embryogenesis, metacaspase ...
