Relative expression levels in 5 dpf wild type zebrafish larvae treated with 5 µM of BGJ398.

Exposure windows were 0–12 and 24–36 hpf. Exposed fish (n = 8) were compared to a DMSO control (n = 8, final concentration 0.1%). (A) Expression of fgfr s showing differential expression in fgfr1a, fgfr1b, fgfr2 and fgfr4. (B) Expression of genes involved in bone formation. (C) Genes involved in cartilage formation. From col9a1b one outlier (p < 0.01 in Grubbs’ test) was removed. (D) Neural crest cell marker genes. All data are presented as box plots, with median represented by a line within the box; interquartile ranges by the boxes, 5–95 confidence intervals by whiskers and means indicated by “+” symbol. All the data were analyzed using a Kruskal–Wallis test followed by a Dunn’s multiple comparison test. Asterisks indicate significant differences; p < 0.05, ∗∗p < 0.01, ∗∗∗p < 0.001.
