Work in Caenorhabditis elegans has been instrumental in deciphering the molecular basis of programmed cell death. However, despite extensive characterization of broadacting cell death genes, the molecular events triggering cell-specific activation of the cell death machinery remain, for the most part, unknown. In some C. elegans somatic cells, transcription of the egl-1 /BH3-only gene is believed to promoted cell-specific death. EGL-1 protein inhibits the CED-9/Bcl-2 protein, resulting in release of the caspase activator CED-4/Apaf-1. Subsequent activation of CED-3 caspase by CED-4 leads to cell death. But despite the important role of egl-1 transcription in promoting CED-3 activity in cells destined …
