　　真核细胞中，核膜将贮存遗传信息的DNA与翻译遗传信息的核糖体分隔在细胞核与细胞质中。由RNA介导的遗传信息跨核膜传递为所有真核生物生命活动所必需。新生pre-mRNA在细胞核内完成一系列复杂加工后，成熟mRNA被转运到细胞质中进行翻译。mRNA出核转运与pre-mRNA加工过程相互偶联，确保遗传信息的精准表达。细胞核中普遍存在RNA质量监控系统，可快速识别并降解携带错误遗传信息的或异常mRNA，从而保证遗传信息的准确传递。新生转录本被快速、准确地分选到出核或降解通路是遗传信息高效、精准传递的基本保证，具有重要生物学意义。本实验室自2008年成立以来，主要围绕“新生转录本出核和降解的命运决定与调控”这一基因表达领域的关键科学问题，系统性地开展mRNA出核与加工的复杂关联、RNA的质量控制和核内降解及其调控两个方向的研究工作。具体如下。

　　利用分子与细胞生物学、生物化学、化学生物学及多种组学研究手段及技术，重点研究：

　　1、mRNA出核与pre-mRNA加工的复杂关联;

　　2、RNA的质量控制和核内降解及其调控;

　　3、细胞核亚结构调控RNA出核或降解的生理病理机制。
