    研究方向:
  • 减数分裂启动
    研究工作:
  •   减数分裂的诞生是生命进化史上的标志性事件,意味着生命有了新的繁衍方式——有性生殖。因此,减数分裂是生物有性生殖的根本基础,也是保证物种繁衍、染色体数目稳定和物种适应环境变化而不断进化的基本前提。所以,减数分裂的调控机制是探索生命奥秘的关键科学问题。

      从单细胞酵母到哺乳动物,减数分裂的关键生物学过程包括同源染色体配对联会、重组交换与分离都高度保守,然而不同生物体之间调控减数分裂的分子机制却显著不同。如绝大多数调控酵母、果蝇、线虫减数分裂的关键基因,在哺乳动物中并无同源基因存在。减数分裂启动是有丝分裂细胞转换为减数分裂细胞的关键步骤。就生命科学研究现状而言,学术界对哺乳动物减数分裂启动的调控机制几乎一无所知。同时,减数分裂至今还难以在体外实现,而在体外重建体内的减数分裂过程对阐明遗传稳定性、基因多样性的起源和表观遗传重编程发生的程度具有重大意义,对遗传疾病的防治、干预和男性不育的治疗以及对物种改良、动物保种都具有重要价值。

      本实验室将针对“减数分裂如何启动?”这一重大科学问题,综合应用分子生物学、遗传学、功能基因组学、蛋白组学、系统生物学等技术手段,致力于以下研究:

      1. 减数分裂启动和发展的调控机制:绘制哺乳动物减数分裂启动和发展过程中RNA(mRNA和非编码RNA)和蛋白质动态变化和其修饰图谱及其调控的酶系图谱,揭示这种动态变化及其修饰发生的分子基础。

      2. 减数分裂启动和发展的表观遗传调控机制:以 RNA甲基化、组蛋白修饰和染色质重塑为重点,阐明哺乳动物减数分裂启动和发展过程中的表观遗传变化及其机制。

      3. 微环境对减数分裂启动和发展的作用及其机制

      4. 减数分裂体外重建技术: 建立包括人精原干细胞在内的精原细胞培养、体外分化及减数分裂的技术平台,实现在培养皿中培养获取单倍体精子细胞。
