Caspase CED-3 acts upstream of CED-7 in axon regeneration. a Caspase recognition sequence of CED-7. The CED-3 recognition sequence, DQXD, in its C-terminal region is boxed with a magenta line. b Percentages of axons that initiated regeneration 24 h after laser surgery in the L4 stage. The number (n) of axons examined are shown. Error bars indicate 95% CI. *P < 0.05, **P < 0.01, and ***P < 0.001 as determined by Fisher’s exact test. NS: not significant
