Fig. 1 agrp Is Required for Normal Somatic Growth in Larval Zebrafish
(A–D) Representative fish at 3 dpf following injection at day 0 with morpholino oligonucleotides designed to inhibit expression of each of the zebrafish agouti proteins (A). Body lengths (jaw to tail fin) of injected fish were measured using a micrometer at 5 dpf, showing a dose-responsive inhibition of growth following morpholino blockade of agrp expression (B). Body lengths corresponding to fish injected at day 0 were measured at 14 dpf, showing partial restoration of length (C). Body lengths at 5 dpf following injection of zygotes with 5 ng morpholino oligonucleotide are indicated, plus 30 pg capped agrp RNA, where indicated, showing partial rescue of growth (D). Bars indicate mean ± SEM. n = 30 (B), 10 (C), and 18–23 (D). Statistical significance was tested by one-way ANOVA followed by Tukey′s post test (p < 0.05; p < 0.01; p < 0.001). See also Figure S1
