杜氏肌营养不良症 (DMD) 是一种 X 连锁致死性肌肉疾病,由编码肌营养不良蛋白的 Dmd 基因突变引起。 DMD 模型动物,例如 mdx 小鼠和犬 X 连锁肌营养不良犬,已广泛用于开发 DMD 治疗方法。在这里,我们展示了使用簇状间隔短回文重复序列 (CRISPR)/Cas 系统生成 Dmd 突变大鼠,这是一种基于 RNA 的基因组工程技术,也适用于大鼠。我们同时靶向大鼠 Dmd 基因中的两个外显子,导致 F0 代中肌营养不良蛋白表达缺失。 Dmd 突变大鼠表现出肌肉力量下降,骨骼肌、心脏和膈肌出现退行性/再生表型。这些突变可遗传给下一代,F1 代雄性大鼠的骨骼肌表现出相似的表型。这些模型大鼠应该被证明有助于开发治疗 DMD 的治疗方法。
Duchenne muscular dystrophy (DMD) is an X-linked lethal muscle disorder caused by mutations in the Dmd gene encoding Dystrophin. DMD model animals, such as mdx mice and canine X-linked muscular dystrophy dogs, have been widely utilized in the development of a treatment for DMD. Here, we demonstrate the generation of Dmd-mutated rats using a clustered interspaced short palindromic repeats (CRISPR)/Cas system, an RNA-based genome engineering technique that is also adaptive to rats. We simultaneously targeted two exons in the rat Dmd gene, which resulted in the absence of Dystrophin expression in the F0 generation. Dmd-mutated rats exhibited a decline in muscle strength, and the emergence of degenerative/regenerative phenotypes in the skeletal muscle, heart, and diaphragm. These mutations were heritable by the next generation, and F1 male rats exhibited similar phenotypes in their skeletal muscles. These model rats should prove to be useful for developing therapeutic methods to treat DMD.
