Fig. 3 The C&E Defects in Like1 Morphants Can Be Rescued by Re-establishing smad2 Signaling (A) Schematic of the morpholino used to induce exon 9 skipping (S2-i8e9-MO). (B) Immunoblotting of detergent extracts reveals a reduction in total and phospho-Smad2 protein expression in the S2-i8e9-morphants. (C–E) S2-i8e9-MO induction of smad2 mis-splicing phenocopied the C&E defects caused by Like1 knockdown, as indicated by altered morphology (C, red arrow) and alterations in ntl/hgg1/dlx3b and lefty1 expression and distribution, as measured by in situ hybridization (D, 10 hpf, red arrows, anterior dorsal view; E, 16 hpf, lateral view). (F–H) mRNA encoding constitutively activated smad2 (Ca-Smad2, 20 pg) was used for injection alone or co-injected with Like1-A-MO. Embryo morphology (F) as well as the abnormal distribution of ntl (G, red arrows) and myod1 (H, red arrows) at 10 hpf can be rescued by ectopic expression of Ca-Smad2. All embryos are dorsal view with the anterior on top at 10 hpf. All results are representative of at least three experiments performed. See also Figure S3.
