Abstract: Based on extensive in vivo studies in animals, it has now been discovered that KGF stimulates proliferation, growth and differentiation in various cells of epithelial tissue, besides keratinocytes. This better understanding of the biological effects of KGF in vivo enables the use of this polypeptide as a therapeutic agent, suitably formulated in a pharmaceutical composition, for the specific treatment of disease states and medical conditions afflicting tissues and organs such as the dermal adnexae, the liver, the lung, and the gastrointestinal tract.

Abstract: DNA isolates coding for sialyltransferase which contain a conserved region of homology and methods of obtaining such DNA are provided, together with expression systems for recombinant production of sialyltransferase.

Abstract: Disclosed are novel peptides that modulate inflammatory heart disease. Also disclosed are DNA molecules encoding the peptides, and methods of making the peptides.

Abstract: Disclosed are novel polypeptides possessing part or all of the primary structural conformation and one or more of the biological properties of mammalian erythropoietin ("EPO") which are characterized in preferred forms by being the product of procaryotic or eucaryotic host expression of an exogenous DNA sequence. Illustratively, genomic DNA, cDNA and manufactured DNA sequences coding for part or all of the sequence of amino acid residues of EPO or for analogs thereof are incorporated into autonomously replicating plasmid or viral vectors employed to transform or transfect suitable procaryotic or eucaryotic host cells such as bacteria, yeast or vertebrate cells in culture. Upon isolation from culture media or cellular lysates or fragments, products of expression of the DNA sequences display, e.g., the immunological properties and in vitro and in vivo biological activities of EPO of human or monkey species origins.

Abstract: MSP analogs which have increased heterodimer formation and enhanced biological activity compared recombinant MSP are provided. The analogs are constructed by substituting unpaired cysteine residues which may interfere with interchain disulfide bonding. DNA sequences encoding MSP analogs, vectors and host cells for the expression of MSP analogs, and pharmaceutical compositions are also provided. The analogs may be used to treat conditions treatable by MSP such as gastrointestinal or hematopoietic disorders.

Abstract: The present invention relates to a process for purifying polyethylene glycols (PEGs) which utilizes hydrophobic interaction chromatography (HIC) to separate the PEGs based on their size and on their end-group functionality. The purified PEGs can be used to modify biologically active molecules and improve overall production of such molecules.

Abstract: A novel neurotrophic factor referred to as glial cell line-derived neurotrophic factor (GDNF) has been identified and isolated from serum free growth conditioned medium of B49 glioblastoma cells. Rat and human genes encoding GDNF have been cloned and sequenced. A gene encoding GDNF has been subcloned into a vector and the vector has been used to transform a host cell in order to produce biologically active GDNF in a recombinant DNA process. Antibodies to GDNF are disclosed, as well as methods for identifying members of the GDNF family of neurotrophic factors.

Abstract: The survival and proliferation of Schwann cells can be promoted by culturing such cells in the presence of peptides derived from the EGF-like domain of proteins from the NDF/heregulin family. Colon epithelial cells can be stimulated to multiply and differentiate by culturing such cells in the presence of the same peptides.

Abstract: The present invention relates generally to methods for preventing and/or treating injury or degeneration of cochlear (and vestibular) hair cells and spiral ganglion neurons (as well as vestibular neurons--Carpa's neurons) by administering glial cell line-derived neurotrophic factor (GDNF). The invention relates more specifically to methods for treating sensorineural hearing loss and vestibular disorders.

Abstract: The present invention relates to monoclonal antibodies specific for a cell receptor specific for human stem cell factor (hSCF) as well as pharmaceutical compositions containing such monoclonal antibodies and uses of such monoclonal antibodies.

Abstract: Disclosed are nucleic acid molecules encoding polypeptides that specifically bind telomerase RNA. Also disclosed are methods of preparing the nucleic acid molecules and polypeptides, and methods of using these molecules.

Abstract: Polypeptide growth factors, termed PDFs, are described which are derived from placental tissue and promote the proliferation, growth and survival of prostate cells and epithelial cells. Nucleic acid molecules encoding the polypeptides are also described which are useful in recombinant methods for the production of the polypeptides.

Abstract: Non-human mammals comprising a disrupted MSH2 gene are disclosed. More particularly, animals having a disruption in one or both alleles of the MSH2 gene or a homolog of the MSH2 gene are disclosed. Animals homozygous for the disruption are viable past the embryonic stage of development but show an increased incidence of lymphoma, intestinal adenomas and carcinomas, and squamous cell tumors of the skin. Specifically disclosed are mice whose genome comprises a disrupted MSH2 gene such that the mice exhibits an increase in the incidence of spontaneous lymphoma over the incidence of spontaneous lymphoma in wild type mice.

Abstract: The present invention broadly relates to chemical modification of biologically active proteins or analogs thereof. More specifically, the present invention describes novel methods for site-specific chemical modification of various proteins, and resultant compositions having improved biocompatibility and bioactivity.

Abstract: Analogs of the serine protease inhibitors in which the amino acid sequence is varied slightly are disclosed, which analogs variously show improved properties including improved resistance to oxidative inactivation, improved ability to inhibit pancreatic elastase, improved ability to inhibit cathepsin G, and improved ability to inhibit trypsin.

Abstract: Disclosed are nucleotide sequences encoding a novel polypeptide termed LSIRF. Also disclosed are methods of preparing the polypeptide and uses thereof.

Abstract: Antibodies and fragments thereof which activate an erythropoietin receptor and stimulate erythropoiesis are described. Also described are hybridoma cell lines which produce the antibodies and methods and compositions for the treatment of anemia.
