目前,大鼠遗传学工具箱缺乏将定点的、可遗传的突变引入基因组以创造基因敲除动物的能力。使用旨在靶向整合报告基因和两个内源性大鼠基因(免疫球蛋白 M (IgM) 和 Rab38)的工程化锌指核酸酶 (ZFN),我们证明,将编码 ZFN 的 DNA 或 mRNA 单次注射到单细胞大鼠胚胎中会导致动物在目标位点发生 25-100% 的破坏。这些突变通过种系忠实而有效地传递。我们的数据证明了四个月内对多种大鼠品系进行靶向基因破坏的可行性,为人源化单克隆抗体平台和其他人类疾病模型铺平了道路。
The toolbox of rat genetics currently lacks the ability to introduce site-directed, heritable mutations into the genome to create knockout animals. Using engineered zinc-finger nucleases (ZFNs) designed to target an integrated reporter and two endogenous rat genes, Immunoglobulin M (IgM) and Rab38, we demonstrate that a single injection of DNA or mRNA encoding ZFNs into the one-cell rat embryo leads to a high frequency of animals carrying 25–100% disruption at the target locus. These mutations are faithfully and efficiently transmitted through the germline. Our data demonstrate the feasibility of targeted gene disruption in multiple rat strains within four months time, paving the way to a humanized monoclonal antibody platform and additional human disease models.
