研究方向:
1. 【染色質(zhì)結(jié)構(gòu)調(diào)控基因表達(dá)的功能機(jī)制】
DNA包裹組蛋白形成的染色質(zhì)結(jié)構(gòu)是基因表達(dá)的基本元件。染色質(zhì)表觀遺傳狀態(tài)和轉(zhuǎn)錄活性受到轉(zhuǎn)錄因子、表觀修飾因子、基因組序列和結(jié)構(gòu)等方面的嚴(yán)格調(diào)控?;蚪M二級(jí)結(jié)構(gòu),包括非B型DNA結(jié)構(gòu)G4和R-loop,在遺傳信息表達(dá)中起關(guān)鍵調(diào)控性作用。G4與R-loop的異常累積可導(dǎo)致轉(zhuǎn)錄起始和延伸障礙、染色質(zhì)不穩(wěn)定、DNA復(fù)制異常,進(jìn)而造成細(xì)胞功能紊亂、胚胎發(fā)育異常及相關(guān)人類(lèi)疾病。研究其特異性調(diào)控對(duì)于理解不同細(xì)胞間的轉(zhuǎn)錄調(diào)控和命運(yùn)切換具有重要意義。實(shí)驗(yàn)室在國(guó)際上首次鑒定了ZEBRA (ZNF281,BRCA2,EMSY,QSER1)復(fù)合物,其通過(guò)維持染色質(zhì)的DNA-RNA雜交三鏈結(jié)構(gòu)R-loop(R環(huán))動(dòng)態(tài)平衡,影響基因轉(zhuǎn)錄和DNA復(fù)制,介導(dǎo)干細(xì)胞多能性。實(shí)驗(yàn)室將繼續(xù)致力于染色質(zhì)結(jié)構(gòu)介導(dǎo)基因轉(zhuǎn)錄調(diào)控的機(jī)制探究,及其如何影響疾?。ò[瘤等)發(fā)生發(fā)展。
2.【表觀遺傳與基因組印記調(diào)控新機(jī)制探究】
基因組印記是一種非孟德?tīng)柺降奶厥膺z傳現(xiàn)象,受印記調(diào)控的基因(印記基因)呈父或母源特異性單拷貝表達(dá)。印記基因?qū)τ趥€(gè)體的生長(zhǎng)發(fā)育起到至關(guān)重要的作用,其異常會(huì)導(dǎo)致嚴(yán)重的多器官發(fā)育缺陷、智力障礙以及惡性腫瘤,如Angelman綜合征、Beckwith-Wiedemann 綜合征及Prader-Willi 綜合征。一直以來(lái),表觀遺傳,包括DNA甲基化以及組蛋白H3K9甲基化,是調(diào)控基因組印記的唯一且經(jīng)典機(jī)制。實(shí)驗(yàn)室前期的研究在國(guó)際上首次發(fā)現(xiàn)轉(zhuǎn)錄延伸因子AFF3可結(jié)合在抑制性的甲基化印記控制區(qū)ICR,與表觀遺傳機(jī)器互作,雙向調(diào)控印記控制區(qū)ICR與增強(qiáng)子,以維持正確的基因組印記狀態(tài)。
實(shí)驗(yàn)室將進(jìn)一步探究表觀遺傳與基因組印記調(diào)控的新機(jī)制,探究增強(qiáng)子如何與ICR及表觀調(diào)控網(wǎng)絡(luò)互作,并結(jié)合多種疾病與發(fā)育模型中來(lái)探索基因組印記與X染色體失活的調(diào)控機(jī)制,為印記基因參與重大疾病發(fā)生發(fā)展提供新思路與新認(rèn)識(shí)。
3.【表觀遺傳與疾病發(fā)生發(fā)展】
癌癥等疾病的產(chǎn)生是諸多遺傳因素共同作用的結(jié)果,除了基因突變外,表觀遺傳學(xué)變化導(dǎo)致的轉(zhuǎn)錄調(diào)控遺傳也被認(rèn)為是癌癥產(chǎn)生的重要因素。研究癌癥表觀遺傳調(diào)控,可以溯源癌癥的發(fā)生過(guò)程、指針癌癥的惡性程度、尋找癌癥新的治療靶標(biāo)。實(shí)驗(yàn)室前期發(fā)現(xiàn)ZEBRA復(fù)合物通過(guò)轉(zhuǎn)錄調(diào)控、表觀遺傳修飾調(diào)控等多種方式影響惡性腫瘤疾病進(jìn)程。我們將進(jìn)一步探究表觀遺傳調(diào)控異常和疾病發(fā)生發(fā)展的關(guān)系,以期尋找潛在的癌癥分子治療靶標(biāo)。
