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. Claudin-3 and claudin-4 being receptors for Clostridium Perfringens enterotoxin, this toxin may be used as a novel therapeutic agent to treat ovarian serous papillary tumors.

This invention also provides methods for inhibiting the onset of, and treating, osteopontin-related disorders, as well as compositions for practicing the same. This invention further provides methods for determining the amount of osteopontin in a sample, and a kit for practicing the same. This invention also provides methods for determining whether an agent reduces the amount of osteopontin in an osteopontin-expressing cell. Finally, this invention provides methods for treating a subject afflicted with a disorder mediated by an endogenous protein.

Various therapeutic polynucleotides are provided along with their use to treat a variety of disease states. The chimeric polynucleotides disclosed herein comprise an OPN aptamer linked to an OPN-specific therapeutic oligonucleotide in order to deliver the OPN-specific therapeutic polynucleotide to the site of OPN expression. Thus, the specificity of OPN aptamers allows delivery of therapeutic molecules to the site of unhealthy tissue. Accordingly, the chimeric polynucleotides disclosed herein can reduce at least one symptom of a disease or unhealthy condition by delivering an OPN-specific therapeutic oligonucleotide that interferes with a disease promoting factor.

The invention relates to the technical field of formula milk powder, and in particular relates to infant formula milk powder. The formula milk powder is rich in 0.02wt%-0.24wt% of osteopontin.

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 function. 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.
