Bisphenol A (BPA), a well-known endocrine disruptor, is metabolized and eliminated rapidly from the body in adult animals. However, many authors have reported that perinatal BPA exposure alters development of the brain, reproductive system and behavior in the next generation. Recently, BPA substitutes, especially bisphenol F (BPF), have been used because of concerns about the influence of BPA on children, although the actual effects on the next generation are unknown. In this study, we observed behavioral adverse effects of the offspring of mice exposed to BPA or BPF in fetal period. Female C57BL/6 mice were given oral BPA or BPF (0 or 10 mg/kg body weight) daily from gestational day 11.5 to 18.5. The open field test, the elevated plus maze test and the forced swim test were performed at postnatal week 10. BPF exposure altered offspring behavior significantly, resulting in increases in anxiety and depressive state. The influence of BPF was stronger than that of BPA. We demonstrated novel evidence that BPF influences the behavior of offspring.
双酚A(BPA)是一种著名的内分泌干扰物,在成年动物体内会迅速代谢并排出体外。然而,许多作者报告称,围产期暴露于双酚A会改变下一代的大脑发育、生殖系统和行为。最近,由于担心双酚A对儿童的影响,双酚A替代品,尤其是双酚F(BPF)已被使用,尽管其对下一代的实际影响尚不清楚。在本研究中,我们观察了胎儿期暴露于双酚A或双酚F的小鼠后代的行为不良反应。从妊娠第11.5天至18.5天,每天给雌性C57BL/6小鼠口服双酚A或双酚F(0或10毫克/千克体重)。在出生后第10周进行旷场试验、高架十字迷宫试验和强迫游泳试验。暴露于双酚F会显著改变后代行为,导致焦虑和抑郁状态增加。双酚F的影响比双酚A更强。我们证明了双酚F会影响后代行为的新证据。
