    研究方向:
  • 表观遗传调控及其与癌症等重大疾病的关系
    研究工作:
  • 多细胞生物的个体发育是一个复杂而奇妙的过程,从最原始的一个受精卵细胞发育成由不同细胞类型组成的个体,体现出细胞在时间与空间上的多样性。而这些不同细胞类型的大部分基因序列并没有改变,那么各种基因是如何实现时间空间上的表达调控等问题成为了后基因组学时代重大的科学研究问题。

    以染色质共价修饰为主要标志的表观遗传学(epigenetics),基于其不改变基因序列而引起可遗传的基因转录调控理论,为解决这一科学问题提供了一个新的研究方向。染色质共价修饰有二个方面:一是针对DNA本身的修饰,研究比较成熟的是胞嘧啶碱基第5位碳原子上的甲基化以及羟甲基化;二是对组蛋白的修饰。这两种修饰都会引起染色质结构和基因转录活性的变化。因而形成了一套相对于基本遗传学基因水平的表观遗传系统。

    在这个系统中,不仅涉及到基因如何响应内外环境的变化从而实现在时间和空间上的表达调控,而且众多癌症与重大疾病都与之息息相关。表观遗传网络也作为整合细胞内外环境因素与基因组遗传信息的媒介,直接调控了基因表达,决定了细胞增殖、分化与功能特化,在正常的生命活动中起到不可或缺的作用。特别是一些与个体发育和癌症密切相关的基因,经常发生启动子区域非正常甲基化以及组蛋白修饰的紊乱而引起疾病的发生。

    表观遗传学研究因其作用广泛、影响深远,已经引起了越来越多的重视并成为目前生命科学研究中发展迅速而崭新的研究领域。

    本实验室采用生物化学、细胞生物学和遗传学(包括基因组学)相互依托的实验手段致力于探索:DNA甲基化谱式是如何在胚胎发育早期建立起来的?异常的表观因子会对生殖细胞的发生和早期胚胎的发育产生何种影响?是否存在不依赖于TET和TDG的主动去甲基化?是否存在新的碱基修饰形式?胚胎干细胞与成体干细胞自我更新与分化是如何达到平衡的,以及哪些因素导致了这一平衡的改变而导致肿瘤和疾病发生?对表观遗传信息调控的研究将有助于了解生长发育与疾病发生发展的分子机理,为维护人类健康尤其是再生医学的技术开发提供理论依据。除了对DNA甲基化和氧化的机制感兴趣外,我们还在拓展研究范围,包括建立永生化的精子细胞系,通过囊胚补偿实现器官再生,以及真核生物对磁场的响应机制等方向。
