Abstract
Environmental endocrine chemicals have various adverse effects on the development of vertebrates. Fluorene-9-bisphenol (BHPF), a substitute of bisphenol A (BPA), is widely used in commercial production. The effects of BHPF on development and behavior are unclear. Melatonin plays a protective role under many unfavorable conditions. In this study, we investigated the effects of BHPF on the development and behaviors of zebrafish and whether melatonin reverses effects induced by BHPF. Zebrafish embryos were exposed to 0.1, 10, or 1000 nM BHPF with or without 1 μM melatonin from 2 hours post-fertilization to 6 days post-fertilization. The results showed that 0.1 and 10 nM BHPF had little effect on development. High-dose BHPF (1000 nM) delayed the development, increased mortality and surface tension of embryonic chorions, caused aberrant expression of the key genes (ntl, shh, krox20, pax2, cmlc2) in early development detected by in situ hybridization, and damaged the CaP motor neurons, which were associated with locomotion ability detected by immunofluorescence. Melatonin addition reversed or weakened these adverse effects of BHPF on development, and melatonin alone increased surface tension as the effects of high-dose BHPF. However, all groups of BHPF exposure triggered insomnia-like behaviors, with increased waking activity and decreased rest behaviors. BHPF acted on the hypocretin (hcrt) system and up-regulated the expression of sleep/wake regulators such as hcrt, hcrt receptor (hcrtr), arylalkylamine N-acetyltransferase-2 (aanat2). Melatonin recovered the alternation of sleep/wake behaviors induced by BHPF and restored abnormal gene expression to normal levels. This study showed that high-dose BHPF had adverse effects on early development and induced behavioral alternations. However, melatonin prevented BHPF-induced aberrant development and sleep/wake behaviors. This article is protected by copyright. All rights reserved.
