研究方向

RNA修饰介导的发育与代谢研究

RNA中有超过100种化学修饰被发现，它们的生物学功能和调控机制才刚刚开始被揭示，因此这些科学问题成为目前国际研究的焦点并形成了一个新的领域，表观转录组学(epitranscriptomics)。我们前期首次鉴定了N6-甲基腺嘌呤(m6A)甲基转移酶复合物(又称为writer complex)三个新的、在进化中保守的组分Nito/Rbm15、Xio/ZC3H13和Hakai，并发现它们通过修饰果蝇性别决定主导基因Sxl的mRNA，从而调控其可变剪接(alternative splicing)来控制果蝇的性别决定。实验室今后将使用果蝇和小鼠模型在以下几个方面开展研究：(1)筛选m6A通路中新的因子及动物性别决定途径新的成员；(2)解析m6A修饰在发育和代谢过程中的作用机理；(3)构建在动物体内修改RNA修饰的体系；(4)利用已构建的m6A报告系统筛选影响这一过程的化学小分子；(5)利用在m6A研究过程中积累的技术和手段展开对其它RNA修饰的功能性探索。
