FIG. 2.

RNA transcript levels of genes related to dopamine transport (slc6a3), reception (drd1, drd2a, drd3), and synthesis (th1) in zebrafish exposed to deltamethrin (DLM) during development. Transcript levels were assayed at (A) 72 hpf and (B) 2 wpf. The graphs represent the mean fold change in transcript copy number ± S.E.M of one representative experimental replicate (n = 4). A 1-way ANOVA or a Kruskal-Wallis ANOVA on Ranks was used to determine if there was a significant effect of deltamethrin exposure on transcript levels where appropriate. * indicates a significant difference versus control as determined by Holm-Sidak or Dunn’s post hoc analyses where appropriate (P ≤ 0.05).
