Summary

One point that emerges from the studies of programmed cell death in C. elegans and other organisms is the striking similarity of genes and gene pathways among organisms that are as superficially distinct as worms and humans.

– H. Robert Horvitz, 2002 Nobel Lecture

Overview

Since Caenorhabditis elegans was pioneered as a research tool in the early 1970s, it has become a window for peering into programmed cell death (PCD), also known as apoptosis. A soil-dwelling organism that is 1 mm in length and transparent, C. elegans is well suited for microscopic inquiry. Its reproductive cycle lasts 2 to 3 days and begins with either self-fertilization of a hermaphrodite or cross-fertilization between a hermaphrodite and a male. Forward genetic approaches using random mutagenesis and phenotypic screening, combined with a rapid generation turnover, have made C. elegans a powerful platform for discovery of new genes in PCD.
