染色质结构的动态变化是表观遗传调控的重要基础,与DNA复制、基因转录、DNA损伤修复、基因组稳定性维持等重要生物学事件密切相关。染色质动态源于DNA或组蛋白的序列及化学性质的改变,以及核小体组成和染色质结构的差异,同时也受到组蛋白变体、组蛋白伴侣、组蛋白修饰酶、染色质重塑复合物、非编码RNA等多种表观因子的调节。
本课题组关注的科学问题是染色质动态的调控及功能,我们将运用包括冷冻电镜在内的多种结构生物学手段,结合生物化学、生物物理学、酵母遗传学、单分子力谱、计算生物学等方法,开展两个方向的研究:
1. 核小体编辑
研究染色质重构复合物如何催化组蛋白变体对常规组蛋白进行替换,以及如何实现核小体编辑的人工操控。核小体编辑通过将组蛋白H2A变体精准定位到基因组特定区域进行基因表达调控,其功能异常与癌症等多种疾病密切相关。阐明核小体编辑的作用机制有助于新型表观遗传编辑技术的研发(图一)。
2. DNA损伤修复调控
研究细胞如何选择特定的修复途径对DNA损伤进行修复。DNA损伤"合成致死"效应在癌症治疗中的作用,催生了PARP抑制剂等一线抗癌药物,阐明DNA损伤修复的调控机制有助于发现新的药物靶点,促进抗癌药物的研发(图二)。
