Abstract: Cells and non-human transgenic animals have been engineered to be deficient in the gene encoding the melcanocortin-3 receptor protein (MC-3R). MC-3R deficient transgenic animals have increased fatmass and reduced lean body mass, showing that the MC-3R protein is involved in the regulation of body fat and muscle mass. These MC-3R deficient transgenic animals can be used to select for and test potential modulators of MC-3R. This data allows for methods of screening for MC-3R modulators which effect body weight and associated methods of treating various disorders associated with inappropriate regulation of body weight. The disclosure also relates to a MC-3R/MC-4R double knockout mouse which can be used to select for and test potential modulators (e.g., agonists or antagonists) of MC-3R and/or MC-4R. It is shown that MC-3R serves a non-redundant role, when compared to MC-4R, in the regulation of energy homeostasis.

Abstract: This invention relates to a new family of receptors, growth hormone secretagogue-related receptors, which exhibit moderate sequence identity to both the growth hormone secretagogue receptor (GHS-R) and the neurotensin receptor (NT-R). These newly identified receptors are expressed in a diverse set of tissues. This invention also relates to nucleic acids encoding these receptors, and to the use of these receptors to identify ligands that modulate growth hormone release as well as other modulators of endocrine function.

Abstract: Vascular endothelial cell growth factor C subunit DNA is prepared by polymerase chain reaction techniques. The DNA encodes a protein that may exist as either a heterodimer or homodimer. The protein is a mammalian vascular endothelial cell mitogen and as such is useful for the promotion of vascular development and repair. This unique growth factor is also useful in the promotion of tissue repair.

Abstract: Human, swine and rat growth hormone secretagogue receptors have been isolated, cloned and sequenced. Growth hormone secretagogue receptors are new members of the G-protein family of receptors. The growth hormone secretagogue receptors may be used to screen and identify compounds which bind to the growth hormone secretagogue receptor. Such compounds may be used in the treatment of conditions which occur when there is a shortage of growth hormone, such as observed in growth hormone deficient children, elderly patients with musculoskeletal impairment and recovering from hip fracture and osteoporosis.

Abstract: Adenoviral particles are produced by incubating cells containing a helper adenovirus vector and a helper-dependent adenoviral vector including an Adeno-Associated Virus (AAV) rep gene, such as rep 78. Cells are provided containing a helper adenovirus vector. A helper-dependent adenoviral vector including an AAV rep gene is introduced into the cells, for instance by infection with infective viral particles. The cells are incubated to produce adenoviral particles containing nucleic acid including the AAV rep gene. Advantageously, cells containing helper adenovirus vector are pre-incubated for 0.5-12 hours, preferably about 4 hours, to allow expression of viral proteins required for adenoviral genome replication before introducing the helper-dependent adenovirus vector including an AAV rep gene.

Abstract: In accordance with the present invention, there are provided nucleic acids encoding human metabotropic glutamate receptor subtypes and the proteins encoded thereby. In a particular embodiment, the invention nucleic acids encode mGluR1, mGluR2, mGluR3 and mGluR5 subtypes of human metabotropic glutamate receptors. In addition to being useful for the production of metabotropic glutamate receptor subtypes, these nucleic acids are also useful as probes, thus enabling those skilled in the art, without undue experimentation, to identify and isolate related human receptor subunits. In addition to disclosing novel metabotropic glutamate receptor subtypes, the present invention also comprises methods for using such receptor subtypes to identify and characterize compounds which affect the function of such receptors, e.g., agonists, antagonists, and modulators of glutamate receptor function.
