Normal N2 C. elegans worms were cultured on NGM plates containing E. coli cells carrying vector control or ceMTM3bF1. A. Statistical analysis of morbidity and mortality. B. Survival curves. Data (Mean ± SD, n ≥50) represent the ages at which the indicated symptoms occurred. Back Track, loss of sinusoidal moving tracks; Inactive, failure to move 0.5 cm in 2 hr; Near Death, failure to move 0.5 cm in 24 hr; Death, no pharyngeal pumping and no response to prodding. Borderline cases were usually resolved clearly by the next day of scoring. About 4% of ceMTM1F1-treated worms died of formation of larvae in the womb (worm bagging), and were excluded from this analysis.
