A recombinant antibody in which at least the constant regions in the heavy chain and the light chain have been converted into human-origin regions and which inhibits the binding of an integrin recognizing the RGD sequence to osteopontin or its fragment and inhibits the binding of an integrin recognizing the SVVYGLR sequence or a sequence corresponding thereto to osteopontin or its fragment. This antibody is useful as a remedy for autoimmune diseases and a remedy for rheumatism or rheumatoid arthritis. Thus, a method of treating autoimmune diseases, rheumatism or rheumatoid arthritis is provided. This osteopontin antibody is useful in a diagnostic for rheumatism and a method of diagnosing rheumatism too.

The present invention is directed to diagnostic methods based upon the expression of the protein osteopontin. In particular, it is concerned with assays of urine samples collected from women for the purpose of determining whether they are at increased risk for having ovarian cancer.

An osteopontin containing implant which increases the rate of osseointegration and the percentage of bone apposition is described. In one embodiment, the implant includes osteopontin or an active fragment thereof or an active peptide derived thereform. In another embodiment, the implant includes a material suitable for use in vivo within a subject in combination with a releasable form of osteopontin forming an osteopontin containing implant. The disclosed osteopontin derived peptides bind to various cell types and play important roles in cellular differentiation and / or motility. Many of these interactions are mediated by integrins as disclosed. Antibodies provide a mechanism to abolish or attenuate the activities of the claimed peptides.

The present invention relates to the use of proteins which are differentially expressed in primary brain tumor tissues, as compared to normal brain tissues, as biomolecular targets for brain tumor treatment therapies. Specifically, the present invention relates to the use of immunotherapeutic and immunoimaging agents which specifically bind to one or more of human proteins angiopoietin related protein 2 (ARP-2,) secreted protein acidic, rich in cysteine (SPARC,) c-met proto-oncogene (C-MET,) brevican (BEHAB,) CD-44 antigen (CD-44,) tetraspanin 3 (TSPN3,) pleiotrophin (PTN,) osteopontin (OPN,) vasoactive intestinal peptide receptor-2 (VIPR-2,) and receptor protein tyrosine phosphatase zeta (PTPζ) for the treatment and visualization of brain tumors in patients. The present invention also provides compounds and pharmaceutically acceptable compositions for administration in the methods of the invention. The present invention also provides novel splice variants of protein PTPζ, PTPζ SM1 and PTPζ SM2. Nucleic acid probes specific for the spliced mRNA encoding these variants and affinity reagents specific for the novel proteins are also provided.

A recombinant antibody in which at least the constant regions in the heavy chain and the light chain have been converted into human-origin regions and which inhibits the binding of an integrin recognizing the RGD sequence to osteopontin or its fragment and inhibits the binding of an integrin recognizing the SVVYGLR sequence or a sequence corresponding thereto to osteopontin or its fragment. This antibody is useful as a remedy for autoimmune diseases and a remedy for rheumatism or rheumatoid arthritis. Thus, a method of treating autoimmune diseases, rheumatism or rheumatoid arthritis is provided. This osteopontin antibody is useful in a diagnostic for rheumatism and a method of diagnosing rheumatism too.

Gene expression profiling and hierarchial clustering analysis readily distinguish normal ovarian epithelial cells from primary ovarian serous papillary carcinomas. Laminin, tumor-associated calcium signal transducer 1 and 2 (TROP-1 / Ep-CAM; TROP-2), claudin 3, claudin 4, ladinin 1, S100A2, SERPIN2 (PAI-2), CD24, lipocalin 2, osteopontin, kallikrein 6 (protease M), kallikrein 10, matriptase and stratifin were found among the most highly overexpressed genes in ovarian serous papillary carcinomas, whereas transforming growth factor beta receptor III, platelet-derived growth factor receptor alpha, SEMACAP3, ras homolog gene family, member I (ARHI), thrombospondin 2 and disabled-2 / differentially expressed in ovarian carcinoma 2 (Dab2 / DOC2) were significantly down-regulated. Therapeutic strategy targeting TROP-1 / Ep-CAM by monoclonal chimeric / humanized antibodies may be beneficial in patients harboring chemotherapy-resistant ovarian serous papillary carcinomas.

Monoclonal antibodies immunospecific for osteopontin are disclosed. Also provided are therapeutic methods of use thereof for modulating osteopontin levels for the treatment of autoimmune disorders.

Isolated fibroblast growth factor receptor 5 (FGFR5) polypeptides are provided, together with polynucleotides encoding such polypeptides. Also provided are modulators of FGFR5 gene expression and binding molecules that specifically bind to, and agonize or antagonize, FGFR5 polypeptide finction. Binding molecules include antibodies, and functional fragments thereof, as well as scFv and Camelidae heavy chain IgG that specifically bind to FGFR5 thereby modulating the activity of FGFR5. Such binding agents and modulators of FGFR5 gene expression may be employed for the treatment of disorders including: osteopontin-mediated diseases; autoimmune diseases, such as systemic lupus erythematosus; bone disorders such as osteoporosis and osteopetrosis; and cancers, including cellular carcinomas such as hepatocellular carcinomas.
