哺乳动物基因组可以转录数以千计的长非编码RNA(longnon-coding RNA, lncRNA),lncRNA能够在多种层次以灵活的方式对基因表达进行调控.尽管lncRNA在基因表达调控过程中的作用已经毋庸置疑,但目前只有少数lncRNA的功能和作用机制得到了研究.lnc1343是一条由小核仁RNA宿主基因3所转录的lncRNA,其表达失调与许多人类疾病有密切关联.研究结果表明lnc1343能够通过自身转录本来调控小鼠胚胎干细胞(mouse embryonic stem cells, mESCs)的多能性维持, CRISPR-cas9 介导的lnc1343的转录起始位点和基因座的敲除显著降低了多能性基因(Nanog, Sox2, Oct4)的表达,同时也能通过邻近调控相邻基因Rcc1的表达.此外,通过对Chip-seq数据库的分析,发现lnc1343基因座位存在大量的H3K27ac以及H3K4mel的表观遗传修饰,通过Capture C实验捕获与lnc1343基因座位相互作用的DNA区域,发现大部分相互作用区域位于基因的启动子区,表明lnc1343基因座位可能发挥增强子功能,通过长距离染色质相互作用调控基因表达,进而调控mESCs多能性.总之,lnc1343不仅可以通过自身的转录剪切形成的lncRNA来调控mESCs的多能性,同时也能通过其基因座位调控染色质的长远距离相互作用. 相似文献
