Fig. 4 Pak1 nuclear import is critical for zebrafish development and survival.
(A) Representative images of zebrafish embryos at 4 dpf. Embyros were co-injected with the morpholino (MO1) and either human wt-Pak1 mRNA, human Pak1-NLSmut or human Pak1-LC8mut (last three panels). Uninjected embryos and MO1 only injected embryos are also shown. (B–D) Quantitative analysis of differential zebrafish survival, body length, and extent of cardiac edema at 4 dpf in embryos injected with different morpholino/Pak1 mRNA combinations. For B, percent survival of uninjected control fish is approximately 90%. For D, cardiac edema for experimental fish was normalized to the control fish.
