Neurodevelopmental toxicity of bisphenol AF in zebrafish larvae and the protective effects of curcumin

In this study, the effects of BPAF on neurotoxicity of zebrafish embryos/larvae and whether CUR could reverse effects induced by BPAF were investigated. The results showed that BPAF treatment induced deficits in locomotor behavior, altered the larval brain development, caused aberrant expression of neurogenesis related genes (elavl3,zn5,α-tubulin,syn2a, andgap43), decreased acetylcholinesterase (AChE) activity, and induced oxidative stress, cell apoptosis, and neuroinflammation in zebrafish larvae. CUR addition could block the adverse effects of BPAF on nervous development by attenuated oxidative stress and cell apoptosis induced by BPAF in zebrafish, enhanced the activity of AChE, and increased the expression of genes involved in the pro-inflammatory cytokines (IL-6,IL-1 β,TNF- α, andIL-8). The results of this study indicate that BPAF could induce aberrant development on nervous system. However, CUR exerts neuroprotective effects on BPAF-induced neurotoxicity in zebrafish larvae.
