转录激活因子样效应物核酸酶(TALEN)是一类新的工程化核酸酶,其比先前类型的核酸酶更容易设计以在基因组中的期望位点处切割。我们报告了使用TALEN在培养的体细胞或人多能干细胞中快速有效地产生15个基因的突变等位基因,其中后者我们将靶向细胞系和等基因对照细胞系分化成各种代谢细胞类型。我们证明了细胞自主表型与疾病-血脂异常、胰岛素抵抗、低血糖、脂肪代谢障碍、运动神经元死亡和丙型肝炎感染直接相关。我们几乎没有发现TALEN脱靶效应的证据,但每个克隆系都含有大量独特的突变。鉴于我们能够快速、轻松地推导和表征这些细胞系,我们预计TALEN介导的人类细胞基因组编辑将成为人类生物学和疾病研究的支柱。
Transcription activator-like effector nucleases (TALENs) are a new class of engineered nucleases that are easier to design to cleave at desired sites in a genome than previous types of nucleases. We report the use of TALENs to rapidly and efficiently generate mutant alleles of 15 genes in cultured somatic cells or human pluripotent stem cells, the latter of which we differentiated both the targeted lines and isogenic control lines into various metabolic cell types. We demonstrate cell-autonomous phenotypes directly linked to disease—dyslipidemia, insulin resistance, hypoglycemia, lipodystrophy, motor neuron death, and hepatitis C infection. We find little evidence of TALEN off-target effects, but each clonal line nevertheless harbors a significant number of unique mutations. Given the speed and ease with which we were able to derive and characterize these cell lines, we anticipate TALEN-mediated genome editing of human cells becoming a mainstay for the investigation of human biology and disease.
