Genetic control of programmed cell death in Drosophila melanogaster.
Apoptosis is a genetically controlled form of cell death that is an important feature of animal development and homeostasis. The genes involved in the control and execution of apoptosis are conserved throughout evolution. However, the actual molecular mechanisms used by these genes vary from species to species. In this review, we focus on the genetic components of apoptosis in the fruit fly Dro...
متن کاملGenetic control of programmed cell death in Drosophila.
A gene, reaper (rpr), that appears to play a central control function for the initiation of programmed cell death (apoptosis) in Drosophila was identified. Virtually all programmed cell death that normally occurs during Drosophila embryogenesis was blocked in embryos homozygous for a small deletion that includes the reaper gene. Mutant embryos contained many extra cells and failed to hatch, but...
متن کاملEcdysone-mediated programmed cell death in Drosophila.
During Drosophila development, the steroid hormone ecdysone plays a key role in the transition from embryo into larva and then into pupa. It is during larval-pupal metamorphosis that extensive programmed cell death occurs to remove large obsolete larval tissues. During this transition, ecdysone pulses control the expression of specific transcription factors which drive the expression of key gen...
متن کاملProgrammed 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 کاملCell Death Regulation in Drosophila
Programmed cell death, or apoptosis, is a genetically encoded form of cell suicide that results in the orderly death and phagocytic removal of excess, damaged, or dangerous cells during normal development and in the adult. The cellular machinery required to carry out apoptosis is present in most, if not all cells, but is only activated in cells instructed to die (for review see Jacobson et al.,...
