Effects of hexabromocyclododecane (HBCD) on cardiac development in zebrafish embryos (Danio rerio): the mechanisms involved

Abstract

六溴环十二烷(1,2,5,6,9,10-Hexabromocyclododecane,HBCD)是被运用最广泛的阻燃剂之一,在全球的用量仅次于四溴双酚A和多溴联苯醚。HBCD具有持久性、生物累积性和生物放大效应,因而被定义为持久性有机污染物(persistentorganicpollutants,POPs)。已有研究表明HBCD具有发育毒性、神经毒性、内分泌毒性和生殖毒性,但对心脏发育毒性的研究十分有限,尤其缺乏对心脏发育毒性机制的研究。本研究以斑马鱼和H9C2细胞系为实验模型,采用低浓度HBCD(0,2nM,20nM和200nM)对其进行暴露,应用生态毒理学、分子生物学以及生物信息学技术检测...Hexabromocyclododecane (HBCD) is the third most commonly used brominated flame retardants, following tetrabromobisphenol A and polybrominated diphenyl ethers. HBCD has a strong potential to be persistent, bioaccumulative and biomagnified, so it is listed into persistent organic pollutants. Studies have reported that HBCD can cause developmental, neural, endocrine and reproductive toxicities. Howev...学位:理学博士院系专业:生命科学学院_动物学学号:2162012015376
