Bisphenol A (BPA) and di-n-butyl phthalate (DBP) are well-known endocrine-disrupting chemicals (EDCs) that have human health risks. Chronic exposure to BPA and DBP increases the occurrence of human disease. Despite the potential for exposure in embryonic development, the mechanism of action of BPA and DBP on vertebrate development and disease still remains unclear. In the present study, we identified proteins and protein networks that are perturbed by BPA and DBP during zebrafish (Danio rerio) development. Zebrafish embryos were exposed to environmentally relevant levels of BPA (10 μg/L) and DBP (50 μg/L) for 96 h. By iTRAQ labeling quantitative proteomics, a set of 26 and 41 differentially expressed proteins were identified in BPA- and DBP-treated zebrafish embryos, respectively. Integrated toxicity analysis predicted that these proteins function in common regulatory networks that are significantly associated with developmental and metabolic disorders. Exposure to low concentrations of BPA and DBP has potential health risks in zebrafish embryos. Our results also show that BPA and DBP significantly up-regulate the expression levels of multiple network proteins, providing valuable information about the molecular actions of BPA and DBP on the developmental systems.
双酚 A(BPA)和邻苯二甲酸二丁酯(DBP)是众所周知的内分泌干扰化学物质(EDCs),对人类健康存在风险。慢性暴露于 BPA 和 DBP 会增加人类疾病的发生。尽管在胚胎发育过程中存在潜在暴露的可能性,但 BPA 和 DBP 对脊椎动物发育和疾病的作用机制仍不清楚。在本研究中,我们鉴定了 BPA 和 DBP 在斑马鱼(Danio rerio)发育过程中干扰的蛋白质和蛋白质网络。斑马鱼胚胎在 96 小时内暴露于环境相关浓度的 BPA(10μg/L)和 DBP(50μg/L)下。通过 iTRAQ 标记定量蛋白质组学,在 BPA 和 DBP 处理的斑马鱼胚胎中分别鉴定出 26 种和 41 种差异表达的蛋白质。综合毒性分析预测,这些蛋白质在与发育和代谢障碍密切相关的共同调控网络中发挥作用。低浓度 BPA 和 DBP 的暴露对斑马鱼胚胎存在潜在的健康风险。我们的研究结果还表明,BPA 和 DBP 显著上调了多个网络蛋白的表达水平,为 BPA 和 DBP 对发育系统的分子作用提供了有价值的信息。
