    • The present invention provides a desired rat or a rat cell which contains a predefined, specific and desired alteration rendering the rat or rat cell predisposed to alterations in drug and chemical metabolism by modification of its structure or mechanism. Specifically, the invention pertains to a genetically altered rat, or a rat cell in culture, that is defective in at least one of two alleles of a drug metabolism gene such as the Cyp7b1 gene, the Cyp3a4 gene, etc. In another embodiment, the rat cell is a somatic cell. The inactivation of at least one drug metabolism allele results in an animal with a higher susceptibility to altered drug and chemical metabolism. In one embodiment, the genetically altered animal is a rat of this type and is able to serve as a useful model for altered drug and chemical metabolism or toxicology and as a test animal for autoimmune and other studies. The invention additionally pertains to the use of such rats or rat cells, and their progeny in research and medicine. In one embodiment, the invention provides a genetically modified or chimeric rat cell whose genome comprises two chromosomal alleles of a drug metabolism gene wherein at least one of the two alleles contains a mutation, or the progeny of the cell.
    • 本发明提供了期望的大鼠或大鼠细胞,其包含预定义的特异性和期望的改变,使得大鼠或大鼠细胞易于改变其结构或机制而改变药物和化学代谢。 具体地说,本发明涉及在诸如Cyp7b1基因,Cyp3a4基因等药物代谢基因的两个等位基因中的至少一个中缺失的基因改变的大鼠或培养物中的大鼠细胞。在另一个实施方案中, 大鼠细胞是体细胞。 至少一种药物代谢等位基因的失活导致对改变的药物和化学代谢具有较高敏感性的动物。 在一个实施方案中,遗传改变的动物是这种类型的大鼠,并且能够用作改变的药物和化学代谢或毒理学的有用模型,并且作为用于自身免疫和其他研究的测试动物。 本发明还涉及这些大鼠或大鼠细胞及其后代在研究和医学中的应用。 在一个实施方案中,本发明提供了遗传修饰或嵌合的大鼠细胞,其基因组包含药物代谢基因的两个染色体等位基因,其中两个等位基因中的至少一个含有突变或细胞的后代。

    • This invention relates to the engineering of animal cells, preferably mammalian, more preferably rat, that are deficient due to the disruption of gene(s) or gene product(s) resulting in altered nervous system function. In one aspect, the altered function results in pain in the mammal. In another aspect, the nervous system dysfunction results in prolonged hyperalgesia, allodynia, and loss of sensory function. In another aspect, the invention relates to genetically modified rats, as well as the descendants and ancestors of such animals, which are animal models of altered nervous system function mediated pain and methods of their use. In another aspect, the genetically modified rats, as well as the descendants and ancestors of such animals, are animal models of nervous system dysfunction resulting in prolonged hyperalgesia, allodynia, and loss of sensory function and methods of their use. In another aspect, the present invention provides a method of identifying a compound useful for the treatment or prevention of pain.
    • 本发明涉及由于导致神经系统功能改变的基因或基因产物的破坏而缺乏的动物细胞,优选哺乳动物,更优选的大鼠的工程。 在一个方面,改变的功能导致哺乳动物的疼痛。 另一方面,神经系统功能障碍导致持续的痛觉过敏,异常性疼痛和感觉功能丧失。 另一方面,本发明涉及遗传修饰的大鼠,以及这些动物的后代和祖先,其是改变的神经系统功能介导的疼痛的动物模型及其使用方法。 另一方面,遗传修饰的大鼠以及这些动物的后裔和祖先是神经系统功能障碍的动物模型,导致持续的痛觉过敏,异常性疼痛和感觉功能丧失及其使用方法。 另一方面,本发明提供鉴定可用于治疗或预防疼痛的化合物的方法。
