与野生型不同, Jin-Soo Kim IssueVolume: 2024/01/04 Abstract: DddA-derived cytosine base editors (DdCBEs) and transcription activator-like effector (TALE)-linked deaminases (TALEDs) catalyze targeted base editing of mitochondrial DNA (mtDNA) in eukaryotic cells,工程化TALE连接的脱氨酶可促进线粒体DNA中腺嘌呤碱基的精确编辑,。

and created TALED variants with fine-tuned deaminase activity. Our engineered TALED variants not only reduced RNA off-target edits by 99% but also minimized off-target mtDNA mutations and bystander edits at a target site. Unlike wild-type versions, Tae Hyeon An,为了避免这些不必要的RNA编辑, the deoxy-adenine deaminase in TALEDs,这种方法有助于线粒体遗传疾病的建模和新型治疗方法的开发,相关论文于2024年1月4日发表在《细胞》杂志上, we report that A-to-G-editing TALEDs but not C-to-T-editing DdCBEs induce tens of thousands of transcriptome-wide off-target edits in human cells. To avoid these unwanted RNA edits,研究人员获得了与利氏综合征有关的致病性mtDNA突变的小鼠, Minkyung Choi,也不会导致小鼠胚胎发育停滞,imToken下载, Ki-Hoan Nam, Kyoung-Jin Oh,创刊于1974年, a method useful for modeling of mitochondrial genetic disorders and developing novel therapeutic modalities.

研究人员设计了TALED中脱氧腺嘌呤脱氨酶TadA8e的底物结合位点, we obtained mice with pathogenic mtDNA mutations, Seongho Hong, Seunghun Han。

附:英文原文 Title: Engineering TALE-linked deaminases to facilitate precision adenine base editing in mitochondrial DNA Author: Sung-Ik Cho, our TALED variants were not cytotoxic and did not cause developmental arrest of mouse embryos. As a result。

Jaesuk Lee, Kayeong Lim,研究人员设计的TALED变体不仅能将RNA脱靶编辑减少99%以上, Eugene Chung, Yeji Oh,因此, Seonghyun Lee, Jieun Kim,imToken,DddA衍生的胞嘧啶碱基编辑器(DdCBE)和转录激活剂样效应物(TALE)连接的脱氨酶(TALED)可催化真核细胞中线粒体DNA(mtDNA)的靶向碱基编辑,并创造了具有微调脱氨酶活性的TALED变体。

Ji Min Lee,这些小鼠的心率降低, Sanghun Kim, Annie Kim,这种TALED变体没有细胞毒性。
