Young adults (20 per group) were grown on plates treated with LY294002 (LY; 150 µM) or an equivalent amount of DMSO diluent for 1.5 hr before transfer off food. Pharyngeal pumping was measured periodically as before and the means and S.D. are summarized here. Significant differences from the corresponding DMSO control group have been indicated with asterisks:
p<0.05,
p<0.01.
The daf-2(e1391) strain was grown at 25°C overnight prior to testing, and during food deprivation.
