摘要：

Programmed cell death in the nematode Caenorhabditis elegans requires the activities of the genes ced-3 and ced-4 and is antagonized by the activity of the gene ced-9. Cloning of these C. elegans genes has shown that two of them encode proteins with similarity to vertebrate cell death genes and has revealed that nematodes and mammals share a common pathway for programmed cell death.
