The goal of this study is to establish a Cre/loxP rat resource for conditional and physiologically predictive rat models of human diseases. The laboratory rat (R. norvegicus) is a central experimental animal in several fields of biomedical research, such as cardiovascular diseases, aging, infectious diseases, autoimmunity, cancer models, transplantation biology, inflammation, cancer risk assessment, industrial toxicology, pharmacology, behavioral and addiction studies, and neurobiology. Up till recently, the ability of creating genetically modified rats has been limited compared to that in the mouse mainly due to lack of genetic manipulation tools and technologies in the rat. Recent advances in nucleases, such as CRISPR/Cas9 (clustered regularly-interspaced short palindromic repeats/CRISPR associated protein 9), as well as TARGATT™ integrase system enables fast, efficient and site-specific introduction of exogenous genetic elements into the rat genome. Here, we report the generation of a collection of tissue-specific, inducible transgenic Cre rats as tool models using TARGATT™, CRISPR/Cas9 and random transgenic approach. More specifically, we generated Cre driver rat models that allow controlled gene expression or knockout (conditional models) both temporally and spatially through the Cre-ERT2/loxP system. A total of 10 Cre rat lines and one Cre reporter/test line were generated, including eight (8) Cre lines for neural specific and two (2) lines for cardiovascular specific Cre expression. All of these lines have been deposited with the Rat Resource and Research Center and provide a much-needed resource for the bio-medical community who employ rat models for their studies of human diseases.

建立 Cre-rat 资源,用于创建人类疾病的条件和生理相关模型

本研究的目标是为人类疾病的条件和生理预测大鼠模型建立 Cre/loxP 大鼠资源。实验室大鼠(R . norvegicus)是生物医学研究多个领域的中心实验动物,如心血管疾病、衰老、传染病、自身免疫、癌症模型、移植生物学、炎症、癌症风险评估、工业毒理学、药理学、行为和成瘾研究以及神经生物学。直到最近,与小鼠相比,创造转基因大鼠的能力仍然有限,主要是由于大鼠缺乏基因操作工具和技术。核酸酶的最新进展,例如 CRISPR/Cas9(成簇的规则间隔短回文重复序列/CRISPR 相关蛋白 9)以及 TARGATT™ 整合酶系统,能够快速、高效和位点特异性地将外源遗传元件引入大鼠基因组。在这里,我们报告了一组组织特异性、使用 TARGATT™、CRISPR/Cas9 和随机转基因方法将诱导型转基因 Cre 大鼠作为工具模型。更具体地说,我们生成了 Cre 驱动大鼠模型,允许通过 Cre-ERT2/loxP 系统在时间和空间上控制基因表达或敲除(条件模型)。总共生成了 10 条 Cre 大鼠系和一条 Cre 报告基因/测试系,包括八 (8) 条神经特异性 Cre 系和两 (2) 条心血管特异性 Cre 表达系。所有这些品系都存放在大鼠资源和研究中心,并为使用大鼠模型研究人类疾病的生物医学界提供了急需的资源。我们生成了 Cre 驱动大鼠模型,允许通过 Cre-ERT2/loxP 系统在时间和空间上控制基因表达或敲除(条件模型)。总共生成了 10 条 Cre 大鼠系和一条 Cre 报告基因/测试系,包括八 (8) 条神经特异性 Cre 系和两 (2) 条心血管特异性 Cre 表达系。所有这些品系都存放在大鼠资源和研究中心,并为使用大鼠模型研究人类疾病的生物医学界提供了急需的资源。我们生成了 Cre 驱动大鼠模型,允许通过 Cre-ERT2/loxP 系统在时间和空间上控制基因表达或敲除(条件模型)。总共生成了 10 条 Cre 大鼠系和一条 Cre 报告基因/测试系,包括八 (8) 条神经特异性 Cre 系和两 (2) 条心血管特异性 Cre 表达系。所有这些品系都存放在大鼠资源和研究中心,并为使用大鼠模型研究人类疾病的生物医学界提供了急需的资源。包括八 (8) 条神经特异性 Cre 系和两 (2) 条心血管特异性 Cre 表达系。所有这些品系都存放在大鼠资源和研究中心,并为使用大鼠模型研究人类疾病的生物医学界提供了急需的资源。包括八 (8) 条神经特异性 Cre 系和两 (2) 条心血管特异性 Cre 表达系。所有这些品系都存放在大鼠资源和研究中心,并为使用大鼠模型研究人类疾病的生物医学界提供了急需的资源。
