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.

The instant application discloses methods of treating, reducing, or preventing pain in a mammal, which may include administering a compound capable of modulating a transient receptor potential channel. In one aspect, the TRP channel may be TRPC4. Types of pain contemplated by the present disclosure include acute, chronic, neuropathic, and nociceptive pain.

Genetically engineered or transgenic rats exhibiting a cancer phenotype due to a disruption of germline tumor suppressor genes

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&#x3b3;, TNF-&#x3b1;, IL-2, IL-10, and IL-12. The inactivation of at least one of these cytokine alleles results in an animal with a higher susceptibility to cytokine-cytokine mediated autoimmune and inflammatory disease induction. In one embodiment, the genetically altered animal is a rat of this type and is able to serve as a useful model for cytokine-cytokine mediated autoimmune and inflammatory disease and as a test animal for autoimmune and other studies.
