Table 2.

Wild-type N2 and daf-2 mutant forward duration at increasing times after removal of food

Strain	Mean forward duration off food 5 min	Mean forward duration off food 60 min
N2	26.9 ± 2.4	46 ± 8.0*
daf-2(m577)	25.4 ± 3.4	23.9 ± 2.6
daf-2(e1370)	31.4 ± 5.3	33.1 ± 7.2

The mean duration (sec) of forward movement of wild-type worms (n = 30) increased after 60-min off food. This is not seen in daf-2(m577) (n = 15) or daf-2(e1370) (n = 13). Values are mean ± s.e.m. Mean forward duration was compared between off food for 5 min and 60 min using a paired Student’s t test
