Fig. 3

Pea3 ETS factors are required for target gene responses to FGF signaling. (A–P) Lateral views of embryos injected with MOs indicated above and assayed with probes indicated on the left. Expression of FGF target genes, dusp6 and sef, were unchanged in etv5MO-injected embryos (B, F). In contrast, the double or triple knockdown of Pea3 ETS genes elicited a drastic reduction of dusp6 and sef (C, D, G, H). Knockdown of Pea3 ETS genes resulted in MHB defect as measured by her5 (I–L) and pax2a (M–P) expression. Individual knock-down had minimal effects, while 3EtsMO injections resulted in dramatic reduction of her5 (L) and pax2a (P). (Q) Graph depicting the phenotypic effects of etv5MO, 2EtsMO and 3EtsMO on expression FGF target genes and MHB markers. Red arrowhead marks loss of MHB gene expression.
