Fig. 2 Zebrafish wnt4a can activate the zebrafish eaf1 and eaf2/U19 promoters.
(A) The sequence of the 1.2 kb zebrafish eaf1 promoter and the positions of primers used for subcloning. The transcriptional initial site is indicated by +1. (B) Zebrafish embryos were co-injected with the eaf1 promoter reporter and either a control vector or a vector expressing Myc-Want4a. The luciferase activity was normalized to Renilla and reported as the mean ± standard deviation (SD). (C) The sequence of the 1.0 kb zebrafish eaf2/u19 promoter and the primers used for subcloning. The transcriptional initial site is indicated by +1. (D) The expression of Myc-Wnt4a was verified by Western blot using an anti-Myc antibody. (E) Zebrafish embryos were co-injected with the eaf2/u19 promoter reporter and either a control vector or a vector expressing Myc-Wnt4a. The luciferase activity was normalized to Renilla and reported as the mean ± SD.
