摘要：

Genetic studies of programmed cell death in Caenorhabditis elegans and Drosophila melanogaster have led to the identification of several invertebrate cell death genes. In C. elegans, ced-3 and ced-4 function to kill cells, whereas ced-9 protects cells from death. In Drosophila, the genes reaper and hid act in parallel to promote cell death. Characterization of these genes has revealed that the...
