研究领域：
﻿　　本课题组着眼于生态毒理学的国际前沿领域开展工作，研究新型持久性污染物在野生动物体内的分布特征，以及这些污染物对动物的毒性效应及机制，评估新型持久性污染物对野生动物的健康及繁衍的潜在威胁。
首次摸清了我国圈养野生动物体内全氟烷酸（PFAAs）的分布特征，揭示PFAAs在野生动物体内具有富集及生物放大效应。另外，在大、小熊猫体内发现十溴二苯乙烷（DBDPE）的累积，该结果改变了“十溴二苯乙烷不能被陆生生物利用”的观点，使科学界开始重新审视其生物可利用性和生物效应。
发现全氟烷酸主要抑制脂肪酸和胆固醇的合成和转运。在哺乳动物肝脏，PFAAs主要通过激活过氧化物酶体增殖剂受体（PPARs）及其下游基因的表达发挥毒性作用。
发现稀有鮈鲫暴露PFAAs后，雄性个体出现雌雄同体现象，雄鱼肝脏卵黄蛋白酶原mRNA、蛋白，以及雌激素受体表达均升高，提示PFAAs具有潜在的生殖内分泌干扰作用。观察到PFAA能够干扰哺乳动物睾丸类固醇（睾酮和孕酮）的合成，导致血清睾酮水平明显降低。进一步研究揭示了PFAAs生殖内分泌毒性作用的机理－主要通过抑制类固醇激素合成急性调节蛋白(StAR)对胆固醇的转运干扰性激素的合成。
承担科研项目情况：
