Insulin b Is the Upstream Ligand that Drives Melanophore Dendricity in Wanderlust
(A and B) Morpholino knockdown of the ligand insulin B (insb) in bace2−/− embryos rescues the hyperdendritic melanophores, quantified in (B). The data are from three independent experiments, two-tailed t test, ∗∗∗∗p < 0.0001.
(C–E) Fluorescent ISH shows zebrafish insb ligand mRNA is initially expressed ubiquitously at 24 hpf and then restricted to the head/brain region (arrowhead) in bace2−/− embryos at 48–72 hpf, sense probe controls for background signal. All bar graphs are presented as mean ± SEM. Scale bars: (A) 100 μm, (C and D) 150 μm, and (E) 200 μm.
