【摘要】:正近年發(fā)現(xiàn)的長鏈非編碼RNA(long non-coding RNA,lncRNA)在細(xì)胞生長、發(fā)育、表觀遺傳學(xué)以及腫瘤和心血管疾病發(fā)生過程中,發(fā)揮重要的調(diào)控作用[1-9]。LncRNAs長度為1 000~10 000個堿基,通常是多聚腺苷酸化的,受RNA聚合酶Ⅱ催化轉(zhuǎn)錄合成[3,6,7]。LncRNAs主要分布于胞核,在胞漿中也有存在。很多l(xiāng)ncRNAs與組蛋白修飾、染色質(zhì)重塑和表觀遺傳效應(yīng)有關(guān)[10]。但是,表觀遺傳因子識別它們的作用機制仍然是個謎。在哺乳動物的基因組中,lncRNAs的重要性已引起研究者的重視,lncRNAs可能在
