Dopamine D1- and D2-like receptors oppositely regulate lifespan in C. elegans. A Survival curves of different worm strains cultured at 20 °C (mutant strains were compared with the wild-type N2: ns = not significant; **** indicated P < 0.0001, log-rank test). B Fast body movement spans of different worm strains cultured at 20 °C (mutant strains were compared with the N2: **, P < 0.01, log-rank test). C Progeny produced per day by different worm strains. D The number of worms with different reproductive lifespans. E The developmental stage of different worm strains reached 2.5 days post-hatching. (see Additional file 2 for supporting data). Experiments were performed in three independent biological replicates
