Project Summary Cystic fibrosis (CF) animal models have contributed significantly to understanding the mechanism of underlying disease. However, existing CF animal models have their limitations, either because the animal models fail to reproduce human phenotypes or because the animal models have very high maintenance costs and need specialized care. In addition, lacking good ΔF508CFTR animal model results in poor understanding the pathogenesis of the most common mutation in CF patients and halts CF drug discovery. Using CRISPR/Cas9 we have developed the first rabbit with the disruption of cystic fibrosis transmembrane conductance regulator (CFTR). Initial work on CFTR knockout rabbits (CFTR-/-) revealed lung pathology that is similar to that in human CF patients. In this application, we will test: Aim 1, generate rabbits carrying F508 mutation (CFTRF508/F508) in CFTR locus; Aim 2, generate gut-corrected CFTRF508/F508 rabbits (TgCFTR-CFTRF508/F508); and Aim 3, characterize CFTRF508/F508 rabbits. The success of proposed work will provide an animal model for understanding the underlying molecular mechanisms, accelerating CF drug discovery and testing the efficacy of new drugs.

项目摘要 囊性纤维化（CF）动物模型对了解 潜在疾病的机制。但是，现有的CF动物模型有其局限性， 要么是因为动物模型无法再现人类表型，要么是因为动物 模型的维护成本很高，需要专业护理。另外，缺乏好 ΔF508CFTR动物模型导致不良了解最常见的发病机理 CF患者和停止CF药物发现的突变。使用CRISPR/CAS9我们已经开发了 囊性纤维化跨膜电导调节器的第一只兔子 （CFTR）。 CFTR淘汰兔子的初步工作 （CFTR - / - ）揭示了与人类CF患者相似的肺病理学。在此应用程序中 我们将测试：AIM 1，生成携带F508突变（CFTRF508/F508）的兔子； AIM 2，生成肠道校正的CftrF508/F508兔子（TGCFTR-CFTRF508/F508）;和目标3， 特征CFTRF508/F508兔子。拟议工作的成功将提供动物模型 为了理解潜在的分子机制，加速CF药物发现和 测试新药的效率。 项目摘要/摘要页面6
