真核生物染色質的結構與功能受到眾多表觀調控因子在時間與空間水平上的精準調控,從而確保生命活動的有序進行。DNA組蛋白和核小體的分子結構與組成形式是造成染色質動態(tài)結構變化的基礎,并與其他表觀因子如組蛋白變體、組蛋白伴侶、組蛋白修飾酶和染色質重塑復合物等一起調控染色質的動態(tài)變化和功能。針對這一重要生命過程,課題組主要從以下幾個方向展開研究工作:
1. 重要表觀遺傳調控相關復合體的功能和分子機制
染色質的表觀遺傳調控由相應的大分子復合物來完成,想要充分闡明表觀遺傳信息是如何被呈現(xiàn)和維持的,就必須對這些調控復合物有分子水平上的理解。課題組通過生物化學和冷凍電鏡等手段,對乙?;头核鼗嚓P的表觀復合物開展功能和結構研究,揭示其發(fā)揮生理功能的分子構架特征。這些復合物往往與腫瘤等重要疾病發(fā)生密切相關,我們希望能進一步在分子水平上理解其參與腫瘤發(fā)生發(fā)展的致病機理,并以此鑒定出創(chuàng)新性藥物靶標蛋白。
2.染色質動態(tài)的原位研究
常染色質和異染色質的動態(tài)變化是細胞命運轉換的關鍵,但是這一變化的具體分子過程和調控機制還有很多未知之處。課題組致力于在細胞核內原位環(huán)境中,在傳統(tǒng)細胞生物學研究的基礎上,結合轉錄組、蛋白質組等組學手段和超分辨結構光成像、冷凍電子斷層成像等成像手段,全面揭示多種表觀因子與染色質的相互作用網(wǎng)絡,從而在多尺度上描繪這些表觀因子所主導的染色質動態(tài)變化的分子景觀藍圖。
3. 基于人工智能的冷凍電鏡研究
課題組致力于通過AI算法的開發(fā)與應用,一方面旨在提升Cryo-EM實驗流程的自動化程度和數(shù)據(jù)收集效率;另一方面,則聚焦于對海量成像數(shù)據(jù)進行深度挖掘與分析,以期揭示更為精細、全面的生物分子結構與功能信息,從而為表觀遺傳調控及染色質動態(tài)學的深入研究提供強有力的技術支持與數(shù)據(jù)洞察。
