Motor behavior and motor neuron phenotype induced by tbk1 knockdown in zebrafish larvae. A Western blot quantification (ratio to β-actin level) of tbk1 expression after antisense morpholino oligonucleotide (AMO)- and hTBK1 mRNA injections. B Traces representative of the touch-evoked escape response (TEER) in 48 hpf zebrafish injected with tbk1 or mismatch AMO and hTBK1 mRNA injections. C Quantitative analysis of the TEER velocity of 48 hpf zebrafish larvae injected with tbk1 or mismatch AMO and rescued with mRNA encoding human TBK1. One-way ANOVA with Tukey’s multiple comparisons test was used. *p < 0.05, **p < 0.01). D In vivo quantification of spinal motor neuron axonal length and number in 48 hpf transgenic Tg(mnx1:gal4/UAS:RFP) embryos injected with tbk1 or mismatch AMO.
