Bisphenol F exposure impairs neurodevelopment in zebrafish larvae (Danio rerio).

BPF, a substitute of BPA, has been widely detected in environment and human bodies. Although the genotoxicity, endocrine disrupting effects, reproductive toxicity of BPF has been well documented, its neurodevelopmental toxicity still remains nebulous. In our study, zebrafish embryos were exposed to BPF treatment (0, 7, 70 and 700 μg/L) for 3 or 6 days. Our results showed that BPF exposure markedly decreased zebrafish locomotor behavior, increased oxidative stress, promoted apoptosis and altered brain structure in zebrafish. In addition, the expressions of neurodevelopment related genes were also downregulated upon BPF treatment. In conclusion, our results systematically demonstrated the developmental neurotoxicity of BPF in zebrafish.
