Knocking down znfl1s reduces RA signaling in zebrafishembryos. Whole mount in situ hybridized embryos are positioned animal pole top (8 hpf, A–B) or anterior left (20 hpf, C–F). The expression of cyp26a1 was examined in controls (A, C) and znfl1s morphants (B) at 8 hpf or 20 hpf (D). The expressions of en2a, egr2b and hoxb4a in control embryos (E) and znfl1smorphants (F). All embryos were positioned in lateral view. The arrow points to the expression of hoxb4a in E–F.
