Abstract: The present invention discloses a novel cDNA isolated from human osteoclastoma tissue which encodes a novel polypeptide identified herein as Extracellular/Epidermal Growth Factor HCABA58X owing in part to the presence in its amino acid sequence of epidermal growth factor (EGF) domains characteristic of the EGF family of polypeptides. Also provided are procedures for producing such polypeptides by recombinant techniques and therapeutic uses of the polypeptides. Also disclosed are antagonists against such polypeptides and their uses. Also disclosed are diagnostic assays for detecting altered levels of the polypeptides of the present invention and mutations in the nucleic acid sequences which encode such polypeptides.

Abstract: A human deoxycytidine kinase 2 polypeptide and DNA (RNA) encoding such polypeptide and a procedure for producing such polypeptide by recombinant techniques is disclosed. Also disclosed are methods for utilizing such polypeptide for the treatment of malignancies and viral infections. Antagonist against such polypeptides and their use as a therapeutic to treat immunodeficiency disorders are also disclosed. Diagnostic assays for detecting diseases related to mutations in the hdCK2 nucleic acid sequence and the concentration of the polypeptide encoded by such nucleic acid sequence is also disclosed.

Abstract: There is disclosed a human Corpuscles of Stannius, stanniocalcin polypeptide and DNA(RNA) encoding such polypeptide. There is also provided a procedure for producing such polypeptide by recombinant techniques and for producing antibodies and antagonist/inhibitors against such polypeptide. Another aspect of the invention provides a combination of the polypeptide of the present invention and a suitable pharmaceutical carrier for providing therapeutic treatment of disease or the inhibition of such polypeptide for therapeutic treatment of disease.

Abstract: Human elastase IV polypeptides and DNA (RNA) encoding such polypeptides and a procedure for producing such polypeptide by recombinant techniques and utilizing such polypeptide for therapeutic purposes, for example, restoration of elasticity of arterial walls, improvement of serum lipid abnormality and improvement of serum lipoprotein metabolism are disclosed. Also disclosed are antagonist/inhibitors against such polypeptides and their use in treating inflammation, arthritis, e.g. rheumatoid arthritis and osteoarthritis, septic shock, pancreatitis and limiting tissue damage in ulceration. Diagnostic assays for identifying mutations in nucleic acid sequence encoding a polypeptide of the present invention and for detecting altered levels of the polypeptide of the present invention are also disclosed.

Abstract: A human cytostatin I polypeptide and DNA encoding such polypeptide and a procedure for producing such polypeptide by recombinant techniques is disclosed. Also disclosed are methods for utilizing such polypeptide for the treatment of cancers, particularly breast cancer, leukemias, and other metastases.
