Publication number: 20070191592Abstract: A human urocortin-related peptide with significant sequence homology to the CRF neuropeptide family was identified. A mouse CDNA was isolated from whole brain poly (A+) RNA that encodes a predicted 38 amino acid peptide protein designated herein as urocortin II. Both human URP and mouse Ucn II are structurally related to the other known mammalian family members, CRF and urocortin (Ucn). These peptides are involved in the regulation of the hypothalamic-pituitary-adrenal axis under basal and stress conditions, suggesting a similar role for URP and Ucn IL Synthesized Ucn-II and URP peptide binds with higher affinity to CRF-R2 than to CRF-R1 Ucn II and human URP appear to be involved in the regulation of body temperature and appetite and may play a role in other stress related phenomenon. These findings identify Ucn II and human URP as a new members of the CRF family of neuropeptides, which are expressed centrally and bind to CRF-R2.Type: ApplicationFiled: April 5, 2007Publication date: August 16, 2007Applicant: Research Development FoundationInventors: Wylie Vale, Teresa Reyes, Paul Sawchenko, Jean Rivier, Kathy Lewis, John Hogenesch, Joan Vaughan, Marilyn Perrin

Publication number: 20030032587Abstract: Urocortin (Ucn) is a native mammalian peptide generally related to Urotensin I and Corticotropin Releasing Factor (CRF). Human Ucn has the formula: Asp-Asn-Pro-Ser-Leu-Ser-Ile-Asp-Leu-Thr-Phe-His-Leu-Leu-Arg-Thr-Leu-Leu-Glu-Leu-Ala-Arg-Thr-Gln-Ser-Gln-Arg-Glu-Arg-Ala-Glu-Gln-Asn-Arg-Ile-Ile-Phe-Asp-Ser-Val-NH2 (SEQ ID NO: 15). Rat-derived Ucn is identical but for 2 substitutions, Asp2 for Asn2 and Pro4 for Ser4. Ucn or analogs thereof or pharmaceutically acceptable salts can be administered to humans and other mammals to achieve substantial elevation of ACTH, &bgr;-endorphin, &bgr;-lipotropin, other products of the pro-opiomelanocortin gene and corticosterone. They can also be used to lower blood pressure over an extended period of time, as stimulants to elevate mood and to improve memory and learning performance, as well as diagnostically. Shortened fragments may be administered to release endogenous CRF and/or Ucn in the brain and peripherally.Type: ApplicationFiled: March 26, 2001Publication date: February 13, 2003Applicant: The Salk Institute for Biological StudiesInventors: Wylie W. Vale, Joan Vaughan, Cynthia J. Donaldson, Kathy A. Lewis, Paul Sawchenko, Jean E.F. Rivier, Marilyn H. Perrin

Patent number: 5449766Abstract: Mammalian melanin-concentrating hormone (MCH) is isolated from rat tissue, purified and characterized. These MCH peptides are useful for treating skin disorders, for suppressing the proliferation of skin tumor cells, such as melanomas in mammals, and for modulating the secretion of ACTH. Generally, peptides are provided which have the following formula: ##STR1## or which are naturally occurring homologs of the peptide with said formula. The peptides which are the naturally occurring MCH homologs of mammalian species other than rat can also be obtained using the materials disclosed, as demonstrated specifically with human MCH, which is found to have the same structure as rat MCH. Also disclosed are the amino acid sequences of, and the nucleotide sequences of the cDNAs which encode, the putative precursors of rat MCH and human MCH. These precursors may also include one or more biologically active peptides N-terminally of the mature MCH's.Type: GrantFiled: March 9, 1994Date of Patent: September 12, 1995Assignee: The Salk Institute For Biological StudiesInventors: Joan Vaughan, Wolfgang H. Fischer, Jean E. F. Rivier, Jean-Louis M. Nahon, Francoise G. Presse, Wylie W. Vale, Jr.

Patent number: 5032507Abstract: A method for modulating the rate of erythropoiesis in human hematopoietic progenitor cells. FRP is found to be an efficacious potentiator of, and inhibin a suppressor of, erythropoietin-induced differentiation. FRP and inhibin are shown to be functional antagonists of each other, and thus represent an effective means for modulating erythropoiesis in a number of disease states which are directly caused by or associated with an abnormal rate of erythropoiesis.Type: GrantFiled: November 13, 1987Date of Patent: July 16, 1991Assignees: The Salk Institute for Biological Studies, The Regents of the University of California, Scripps Clinic and Research FoundationInventors: John Yu, Alice L.

Patent number: 4973577Abstract: A 28,000-dalton protein with FSH-releasing activity is isolated from porcine follicular fluid in a multi-step procedure including gel filtration, ion exchange chromatography and several reverse-phase high-performance liquid chromatography steps. The 28 kD protein promotes secretion of FSH, but not of LH, in a rat anterior pituitary monolayer culture system, exhibiting an EC.sub.50 of 0.5 ng/ml. These peptides are dimers of inhibin .beta.-chains of mammals, and homodimers or heterodimers of the .beta..sub.A and .beta..sub.B chains are biologically active to regulate fertility of various mammalian species, including humans.Type: GrantFiled: August 31, 1987Date of Patent: November 27, 1990Assignee: The Salk Institute for Biological StudiesInventors: Wylie W. Vale, Jr., Jean E. F. Rivier, Richard A. McClintock, Anne Corrigan, Joan Vaughan, Joachim Spiess, Nicholas C. Ling, Shao-Yao Ying, Frederick S. Esch, Roger C. L. Guillemin
