Analysis of transgenic zebrafish shows that ECR2 directs expression to the dorsal neural tube and that this expression requires Lef1/TCF sequences. (A1–A4) Lateral view of a 1-dpf zebrafish embryo that is stably transgenic for Sox10:EGPF and transiently transgenic for ECR2:mCherry demonstrates strong dorsal neural tube expression (yellow arrowheads). (B1–B4) Dorsal view of a similarly injected embryo as shown in column A. (C1–C4) Lateral view of a 24-hpf zebrafish embryo that is stably transgenic for Sox10:EGPF and injected with an ECR2ΔLef:mCherry transgene shows that mutations in the Lef1/TCF sequences abrogates expression. (D1–D4) Lateral view of a 24-hpf zebrafish embryo that has been injected with both ECR2:EGFP and ECR2ΔLef:mCherry transgenes shows EGFP expression in the dorsal neural tube (yellow arrowheads). Despite effective transposase activity, no mCherry expression is detected. Scale bar = 500 μm. |
