Function of the PHA-4/FOXA transcription factor during C. elegans post-embryonic development

摘要

Backgroundpha-4 encodes a forkhead box (FOX) A transcription factor serving as the C. elegans pharynx organ identity factor during embryogenesis. Using Serial Analysis of Gene Expression (SAGE), comparison of gene expression profiles between growing stages animals and long-lived, developmentally diapaused dauer larvae revealed that pha-4 transcription is increased in the dauer stage.
