  • Publication number: 20050257279
    Abstract: Cells and non-human transgenic animals have been engineered to be deficient in the gene encoding agouti-related protein (AgRP). AgRP deficient transgenic animals have a reduced day time respiratory quotient (RQ), indicating that AgRP is involved in the regulation of energy metabolism, resulting in the reduced usage of fat as an energy source. These AgRP deficient transgenic animals can be used to select for and test potential modulators of AgRP. This data allows for methods of screening for AgRP modulators which regulate energy metabolism and caloric utilization. The disclosure also relates to a NPY/AgRP double knockout mouse which can be used to select for and test potential modulators (e.g., agonists or antagonists) of AgRP and/or NPY.

  • Publication number: 20050222402
    Abstract: A rat bombesin receptor subtype-3 has been isolated, cloned and sequenced. This receptor is characteristic of the G-protein family of receptors. Isolation of rat bombesin receptor subtype-3 may be used to screen and identify novel bombesin receptor modulators that may contribute to the regulation of endocrine processes, metabolism, or the cell cycle. Such compounds may be used in the treatment of conditions that result from deregulated expression of bombesin receptor subtype-3.

  • Publication number: 20050169839
    Abstract: The present invention relates to a biomarker for the efficacy of appetite suppressant drugs given to humans or other mammals for the treatment of obesity. It further relates to a novel method of determining the efficacy of a test compound given to a subject for the treatment of obesity, wherein the test compound is an appetite suppressant which does not stimulate the release of serotonin. It also relates to a method for following the progress of a therapeutic regime designed to alleviate obesity and to a method for determining the appropriate dosage of an appetite suppressant given to a subject for the treatment of obesity.
