  • Publication number: 20100093604
    Abstract: The present invention relates to a method for identifying a metabolic stabilizing compound by: a) contacting a candidate compound with GPR43, and b) determining whether GPR43 functionality is modulated, where a modulation in GPR43 functionality is indicative of the candidate compound being a metabolic stabilizing compound. In addition, the invention relates to a method for identifying a metabolic stabilizing compound, comprising: a) contacting a candidate compound with GPR43, and b) determining whether GPR43 functionality is increased, wherein an increase in GPR43 functionality is indicative of the candidate compound being a metabolic stabilizing compound. Further, the invention relates to a method for identifying a metabolic stabilizing compound, comprising: a) contacting a candidate compound with GPR43, and b) determining whether GPR43 functionality is decreased, wherein a decrease in GPR43 functionality is indicative of the candidate compound being a metabolic stabilizing compound.

  • Publication number: 20090297537
    Abstract: The present invention concerns combination of an amount of a BRS-3 agonist with an amount of a dipeptidyl peptidase IV (DPP-IV) inhibitor such that the combination provides an effect in lowering a blood glucose level or in increasing a blood GLP-1 level in a subject over that provided by the amount of the BRS-3 agonist alone and by the amount of the DPP-IV inhibitor alone and the use of such a combination for treating or preventing obesity and diabetes and conditions related thereto and conditions ameliorated by increasing a blood GLP-1 level. The present invention also relates to the use of a G protein-coupled receptor to screen for GLP-1 secretagogues.

  • Publication number: 20090270422
    Abstract: The present invention relates to the use of GPR119 receptor agonists for treating or preventing a condition characterized by low bone mass, such as osteoporosis, and for increasing bone mass in an individual. The present invention further relates to the use of a GPR119 receptor agonist in combination with a dipeptidyl peptidase IV (DPP-IV) inhibitor for treating or preventing a condition characterized by low bone mass, such as osteoporosis, and for increasing bone mass in an individual. A GPR119 receptor agonist and the combination of a GPR119 receptor agonist and a DPP-IV inhibitor promote bone formation in an individual.

  • Publication number: 20090253153
    Abstract: The present invention relates to methods of using GPR119 receptor to identify peptide YY (PYY) secretagogues and compounds useful in the treatment of conditions modulated by PYY, such as conditions modulated by stimulation of NPY Y2 receptor (Y2R). Agonists of GPR119 receptor are useful as therapeutic agents for treating or preventing a condition modulated by PYY, such as a condition modulated by stimulation of Y2R. Conditions modulated by PYY such as may be a condition modulated by stimulation of Y2R include bone-related conditions, metabolic disorders, angiogenesis-related conditions, ischemia-related conditions, convulsive disorders, malabsorptive disorders, cancers, and inflammatory disorders.

  • Publication number: 20080312277
    Abstract: The present invention relates to a method for identifying a glycemic stabilizing compound by: a) contacting a candidate compound with GPR41, and b) determining whether GPR41 functionality is modulated, where a modulation in GPR41 functionality is indicative of the candidate compound being a glycemic stabilizing compound. In addition, the invention relates to a method for identifying a glycemic stabilizing compound, comprising: a) contacting a candidate compound with GPR41, and b) determining whether GPR41 functionality is increased, wherein an increase in GPR41 functionality is indicative of the candidate compound being a glycemic stabilizing compound. Further, the invention relates to a method for identifying a glycemic stabilizing compound, comprising: a) contacting a candidate compound with GPR41, and b) determining whether GPR41 functionality is decreased, wherein a decrease in GPR41 functionality is indicative of the candidate compound being a glycemic stabilizing compound.

  • Patent number: 5741673
    Abstract: In accordance with the present invention, there are provided novel homeobox-type pancreatic islet transcription factor proteins useful to bind to tissue-specific elements (TSEs) within a pancreatic islet hormone gene promoter and modulate hormone gene expression both in vivo and in vitro. Nucleic acid sequences encoding such transcription factor proteins and assays employing same are also disclosed. The invention transcription factor proteins can be employed in a variety of ways, for example, to modulate RNA transcription, for production of antibodies thereto, in therapeutic compositions and methods employing such proteins and/or antibodies.
