Abstract: This invention relates to the engineering of animal cells, preferably mammalian, more preferably rat, that are deficient due to the disruption of tumor suppressor gene(s) or gene product(s). 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 human cancer and methods of their use.

Abstract: The invention relates to organisms and compositions comprising one or more stem cells or one or more embryos, wherein the one or more stem cells or one or more embryos comprise one or more of the following mutations: (i) a deletion mutation; (ii) a knockout mutation; and/or (iii) an addition of a heterologous nucleic acid sequence; wherein the one or more mutations of (i), (ii), and/or (iii) are site-specific mutations caused by a Xanthomonas TAL nuclease (XTN). The invention also relates to method of mutating an embryo, iPS cell, stem cell, or more particularly a spermatogonial stem cell by exposing the nucleic acid sequence contained within such embryos or cell with a Xanthomonas TAL nuclease.

Abstract: This invention relates to the engineering of animal cells, preferably mammalian, more preferably rat, that are deficient due to the disruption of tumor suppressor gene(s) or gene product(s). 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 human cancer and methods of their use.

Abstract: This invention relates to a genetically modified or chimeric rat cell whose genome comprises chromosomal alleles of an obesity-diabetes gene (especially, the Mc4r gene or Lep gene), wherein at least one of the two alleles contains a mutation, or the progeny of this cell. The obesity or diabetes gene may affect any of the pathways of obesity and diabetes. The obesity or diabetes gene may predispose the rat to a phenotype of obese and diabetic, lean and diabetic, obese and non-diabetic, non-obese and diabetic or any of the combinations thereof. In another aspect, the invention relates to a desired rat or a rat cell which contains a predefined, specific and desired alteration rendering the rat or rat cell predisposed to obesity or diabetes.

Abstract: The present 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 cytokine-cytokine mediated autoimmune and inflammatory disease. 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 human autoimmune and inflammatory disease and methods of their use. 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 cytokine gene such as the Faslg gene, the Fas gene, etc. In one embodiment, the cytokine gene is the Faslg gene. In another embodiment, the cytokine gene is one of several known cytokine genes, such as Fas, IFN?, TNF-?, IL-2, IL-10, and IL-12.

Abstract: The present invention, relates to methods including compounds, derivatives, antibodies, interfering RNA, biologies, polypeptides, dominant negative effectors, and their use in the treatment of neuropathic pain by inhibition of transient receptor potential (TRP) channels. In another embodiment, this invention relates to inhibitors, antagonists, and agonists of TRPC4. TRPC4 therapeutic agents and modulators include but are not limited to small molecule inhibitors, compounds, amino acid derivatives, polypeptides, RNA interference agents, natural chemicals, ligand derivatives, and ions. TRPC4 therapeutic agents and modulators are developed for the treatment of neuropathic pain, including but not limited to pain sensations such as nociception, hyperalgesia, allodynia, and loss of sensory function.
