Abstract: Polypeptides and polynucleotides useful for detecting, diagnosing, staging, monitoring, prognosticating, in vivo imaging, preventing or treating, or determining the predisposition of an individual to diseases and conditions of the urinary tract, such as urinary cancer, are described. These sequences are derived from keratin/cytokeratin, CAS, or mat-8 polypeptides and polynucleotides. Also provided are antibodies which specifically bind to keratin/cytokeratin, CAS, or mat-8-encoded polypeptides or proteins, which molecules are useful for the therapeutic treatment of urinary tract diseases, tumors or metastases.

Abstract: A novel member of the uteroglobin family of proteins, designated as BU101, is described. BU101 is defined by a set of contiguous and partially overlapping RNA sequences transcribed from breast tissue, and polypeptides encoded thereby. A fully sequenced clone representing the longest continuous sequence of BU101 is also disclosed. These sequences are useful for the detecting, diagnosing, staging, monitoring, prognosticating, preventing or treating, or determining the predisposition of an individual to diseases and conditions of the breast such as breast cancer. Also provided are antibodies which specifically bind to BU101-encoded polypeptide or protein, and agonists or inhibitors which prevent action of the tissue-specific BU101 polypeptide, which molecules are useful for the therapeutic treatment of breast diseases, tumors or metastases.

Abstract: A set of contiguous and partially overlapping cDNA sequences and polypeptides encoded thereby, designated as PS108 and transcribed from prostate tissue, is described. These sequences are useful for the detecting, diagnosing, staging, monitoring, prognosticating, in vivo imaging, preventing or treating, or determining the predisposition of an individual to diseases and conditions of the prostate, such as prostate cancer. Also provided are antibodies which specifically bind to PS108-encoded polypeptide or protein, and agonists or inhibitors which prevent action of the tissue-specific PS108 polypeptide, which molecules are useful for the therapeutic treatment of prostate diseases, tumors or metastases.
