工作经历
2023/07-2024/10 哥伦比亚大学 副研究员
2025/01至今 四川大学华西公共卫生学院 特聘研究员
研究方向(含承担课题)
课题组聚焦真核细胞基因组稳定性与重复序列的表观遗传调控机制,研究亲本组蛋白转运及表观遗传记忆的分子基础,探索亲本组蛋白在DNA复制中的转运机制及其在细胞命运决定中的意义。通过高通量测序、单细胞表观遗传组学和基因编辑等技术,解析基因组重复序列(如L1、ERV等)的表观遗传调控网络及其在疾病中的作用。同时,实验室还致力于开发新型表观遗传组学和基因组学技术,结合人工智能整合多组学数据,揭示基因调控网络。我们的长期研究目标是通过研究表观遗传紊乱在肿瘤进展中的作用,鉴定新型靶点,开发靶向表观遗传调控的治疗策略,为肿瘤精准医学提供新思路。
科研成果

1) 首次发现抑制性组蛋白修饰H3K9me3在DNA复制时的转运机制及其生物学功能(Nature 2023,Molecular Cell 2025)。
2) 首次发现连接组蛋白H1的乙酰化和多聚合糖基化等修饰参与调控DNA损伤修复和基因组稳定性的机制(Cell Research 2018,Nucleic Acids Research 2018);
3) 开发新型表观遗传组学技术eSPAN,并系统鉴定了Pol α和Pol ε等作为亲本组蛋白转运的分子伴侣在核小体组装和基因组稳定性中的调控机制(Science Advances 2020,Nature Protocols 2021)。
4) 阐明表观遗传调控DNA损伤修复关键因子的新机制及其在肿瘤放化疗增敏中的作用(Science Advances 2019)。
