Abstract
This study examined the developmental toxicity of the polycyclic aromatic hydrocarbons (PAHs) 11H-benzo(b)fluorene (BBF) and 4-azapyrene (AP) in comparison to the known teratogen retene. Developmental toxicity assays were performed in zebrafish embryos exposed for 120h. BBF and retene induced a similar dioxin-like phenotype, whereas AP showed distinct effects, particularly craniofacial malformations. Microarray analysis revealed that for BBF and retene, drug metabolism pathways were induced, which were confirmed by subsequent studies of cyp1a gene expression. For AP, microarray analysis revealed the regulation of genes involved in retinoid metabolism and hematological functions. Studies with a panel of CALUX
