研究人员早就认识到,由于转基因序列和内源序列之间的双向影响,将新DNA随机引入基因组可能导致不可预测的遗传效应。因此,突变基因的精确编辑或替换从一开始就一直是基因治疗的主要目标。这一目标看起来是可能的,因为发表的研究表明,使用由核酸酶结构域和单独的设计DNA识别结构域组成的嵌合分子可以实现染色体序列的靶向切割和增强的同源重组(HR)。1,2锌指核酸酶(ZFN)是人工核酸内切酶,其由连接到工程化Cys2His2锌指DNA结合多肽的FokI切割结构域组成。3-5 ZFN已经获得了相当大的发展势头,并且被广泛认为是基因治疗领域中最成熟的核酸酶技术。然而,在聚光灯下15年后,出现了一种新的嵌合核酸酶,转录激活因子样(TAL)效应核酸酶(TALEN)。7-10在这里,我们描述了ZFN和TALENs的功能和设计特点,并讨论了它们作为研究和基因治疗工具的扩展作用。
Researchers have long recognized that the random introduction of new DNA into the genome could result in unpredictable genetic effects due to bilateral influences between transgenic and endogenous sequences. Hence, precise editing or replacement of mutant genes has been a major goal of gene therapy since its inception. That goal looked possible with the publication of studies demonstrating that targeted cleavage of chromosomal sequences and enhanced homologous recombination (HR) could be achieved using chimeric molecules composed of a nuclease domain and separate, designer DNA-recognition domains. 1, 2 Zinc-finger nucleases (ZFNs) are artificial endonucleases that consist of a FokI cleavage domain tethered to engineered Cys2His2 zinc-finger, DNA-binding polypeptides. 3–5 ZFNs have gained considerable momentum and are widely considered the most mature nuclease technology in the gene therapy field. 6 However, after 15 years in the spotlight, a new chimeric nuclease has emerged, Transcription Activator-Like (TAL) Effector Nucleases (TALENs). 7–10 Here, we describe functional and design characteristics of ZFNs and TALENs and discuss their expanding role as tools for research and gene therapy.
