Genetic control of programmed cell death in the Caenorhabditis elegans hermaphrodite germline.
Development of the nematode Caenorhabditis elegans is highly reproducible and the fate of every somatic cell has been reported. We describe here a previously uncharacterized cell fate in C. elegans: we show that germ cells, which in hermaphrodites can differentiate into sperm and oocytes, also undergo apoptotic cell death. In adult hermaphrodites, over 300 germ cells die, using the same apoptot...
متن کاملGenetic control of programmed cell death in the nematode Caenorhabditis elegans.
Studies of the development of the nematode Caenorhabditis elegans established that programmed cell death involves specific genes and proteins and that those genes and proteins act within the cells that die. This finding revealed that cell death is a fundamental and active biological process, much like cell division and cell differentiation. The characterization of genes responsible for programm...

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 کاملProgrammed Cell Death During Caenorhabditis elegans Development.
Programmed cell death is an integral component of Caenorhabditis elegans development. Genetic and reverse genetic studies in C. elegans have led to the identification of many genes and conserved cell death pathways that are important for the specification of which cells should live or die, the activation of the suicide program, and the dismantling and removal of dying cells. Molecular, cell bio...
