双酚A暴露对kisspeptin系统影响的研究进展

Research advances on effects of bisphenol A on kisspeptin system

  • 摘要: 双酚A(BPA)是一类环境内分泌干扰物(EDCs),具有弱雌激素和抗雄激素作用。近年来BPA对生殖系统的影响得到了广泛的研究,包括干扰性分化、性成熟、配子发生、激素生成等。kisspeptin是一组由KiSS-1基因编码的神经多肽,可以通过作用于下丘脑-垂体-性腺轴,调控生殖系统功能。研究提示,kisspeptin系统可能是EDCs干扰性发育与生殖功能的作用靶点。本文总结了BPA对生殖系统的影响、kisspeptin系统的生殖调控功能及性激素在其中的重要作用,并在此基础上综述了BPA暴露对kisspeptin系统影响的研究结果,为未来研究BPA影响生殖系统的作用机制和潜在靶点提供参考依据。

     

    Abstract: Bisphenol A (BPA), with weak estrogenic and anti-androgenic effects, is a kind of environmental endocrine disrupting chemicals (EDCs). In recent years, the effects of BPA on reproductive system have been widely studied, including disrupting sexual differentiation, sexual maturity, gamete production, and steroidogenesis. Kisspeptin, a polypeptide encoded by KiSS-1 gene, is able to regulate reproductive function through hypothalamic-pituitary-gonadal axis. Studies have reported that kisspeptin system may be a potential target of EDCs to disrupt sexual development and reproduction. Based on the effects of BPA on reproductive system, the regulation of kisspeptin on reproduction, and the roles of sexual hormones in the regulation, this review summarized the effects of BPA on kisspeptin system, aiming to provide insights for further studies on the potential mechanism and targets through which BPA disrupts reproductive system.
