该研究揭示了复制叉特异的RNA-DNA杂合体 (Replication Fork-associated RNA-DNAs,RF-RDs) 在转录活跃区域通过抵御核酸外切酶的降解,从而维持转录活跃区复制叉稳定性的作用机制。这项研究首次鉴定出RF-RDs为转录活跃区停滞复制叉的重要保护因子,发现了一条独立于RAD51的复制叉末端保护机制,揭示了转录活跃区基因组稳定...

近年来,Cas9缺口酶 (nCas9) 通过向导RNA (gRNA) 设计,能够精确诱导位点特异性和链特异性的SSBs。研究发现,nCas9在前导链上引发的缺口主要转化为seDSBs,而在滞后链上产生双端双链断裂 (deDSBs) ,揭示了两种链在复制相关断裂修复中存在差异【4】。 复制依赖性DNA损伤的形成与链特异性修复机制...
ALT cells use an alternative lengthening mechanism of telomeres and bear telomeric DNA damage with increased levels of damage-induced long non-coding RNA. Here the AUs show that antisense oligonucleotides (ASO) targeting such RNAs can induce ALT cancer cells selective cell death. ...
