主要成就

研究方向

1. 丁二烯毒性的分子机理研究

丁二烯是一个重要的石油化工产品,用于合成塑料和橡胶。但它也存在于汽车尾气、香烟烟雾、垃圾焚烧产生的烟雾中。因此,城市的空气中存在着低浓度的丁二烯。丁二烯是一个致癌物,被美国环境保护署列为187个“Air Toxic”之一。它的毒性源于其代谢产物,主要有2-乙烯基环氧乙烷、双环氧丁烷、3-丁烯-1,2-二醇和3,4-环氧-1,2-丁二醇。这些代谢产物能够与DNA和蛋白质反应产生各种加成产物。我们将重点研究这些代谢产物与蛋白质的相互作用,以及这种相互作用是怎样扰动细胞内的信号传导过程的。

2. 持久性有机污染物(persistent organic pollutants,POPs)毒性的分子机理研究

持久性有机污染物是一类有机化合物的统称。它们难于通过化学、生物和光解过程降解,因而在环境内长期存在和积累,并能通过食物链在生物组织中富集,进而对人的健康产生危害。POPs包括农药和杀虫剂(如滴滴涕和氯丹)、工业产品(主要指多氯联苯)和工业污染物(主要是二恶英)。这些污染物一般被认为是通过与细胞上的受体结合,扰乱细胞内的生理过程而起作用的。我们将用各种生物化学、分子生物学和细胞生物学的手段(特别是荧光技术)研究POPs对细胞内的信号传导过程的影响的分子机理。

学术成就
