Induction of COX2b but not COX2a by TCDD in whole zebrafish eleutheroembryos. Expression levels of COX2a (A) and COX2b (B) transcripts in whole zebrafish eleutheroembryos at 55 hpf and 72 hpf were determined by qRT-PCR. Embryos were exposed to 1 ppb TCDD (solid black bars) or 0.1% DMSO (solvent control, open bars) from 24 hpf until the determination. Results are expressed as mean ± SEM N= 5 per group. Thirty eleutheroembryos were used for each group. Values with different letters are significantly different (p < 0.05).
