Abstract: The invention provides methods of identifying premalignant and malignant breast cancer, determining lymph node involvement in patients diagnosed with premalignant and malignant breast cancer growths, and methods of treating premalignant and malignant breast cancer. The diagnostic and methods comprise intraductal administration of a targeting molecule either alone acting as an identifying agent, or coupled to an identifying agent; the therapeutic methods comprise intraductal administration of a targeting molecule coupled to a therapeutic agent or administration of a targeting molecule having therapeutic activity in and of itself.

Abstract: The invention is to methods for screening women for breast cancer and precancer by determining a level of an estrogen-related marker. The invention further provides methods of treating such patients identified as having one or more abnormal ductal epithelial cells and an estrogen-related marker. The invention provides methods for screening patient for hormone replacement therapy (HRT), and of monitoring such patients once they begin HRT. The invention provides methods of treating peri-, menopausal or postmenopausal women for both cancer risk reduction and menopausal symptoms (or other conditions related to lowered systemic estrogen levels). The invention also provides kits for the screening, monitoring, and treating methods described.

Abstract: The invention describes a method of screening for factors that modulate gene expression, by detection of factors including factors that stimulate or inhibit cell growth, differentiation or proliferation, factors involved in one or more signal transduction pathways, or factors involved in protein-protein interactions. Identification of such factors that modulate gene expression is accomplished by detection of an intracellular event mediated by the factor. The intracellular event can be an increase or decrease in transcription or translational activities. Detection of the intracellular event is accomplished by any highly sensitive assay targeting a transcription or translation product, including, for example, a bDNA assay to the nascent transcript induced by the factor.

Abstract: This invention relates generally to the field of protein modification, e.g., post-translational modification. In particular, the invention provides a method for detecting protein modification profile in a sample, which method comprises: a) contacting a sample containing or suspected of containing a target protein with a capture molecule, or a plurality of capture molecules, immobilized on a solid support, said capture molecule is capable of specifically binding to said target protein, whereby said target protein is immobilized on said solid support; and b) assessing modification status and/or identity of said immobilized target protein. Kits and arrays useful for detecting protein modification are also provided. Arrays, kits and methods useful for detecting enzymatic activities, especially protein modification enzymatic activities, are further provided.

Abstract: This invention relates generally to the field of target detection. In particular, the present inventions provides for methods and compositions for assaying a plurality of different non-nucleic acid targets or for assaying activities of a plurality of enzymes using, inter alia, oligonucleotide identification (ID) tags.

Abstract: This invention relates to human fibroblast growth factor (FGF 98), and to variants thereof and to polynucleotides encoding FGF 98. The invention also relates to diagnostic and therapeutic agents related to the polynucleotides and proteins, including probes and antibodies.

Abstract: The disclosure describes methods of identifying and treating premalignant and malignant breast cancer, and systems and kits for the same. The diagnostic methods comprise intraductal administration of agents that can clear in the body comprising a targeting molecule either alone acting as an identifying agent, or coupled to an identifying agent; the therapeutic methods comprise intraductal administration of agents that can clear n the body comprising a targeting molecule coupled to a therapeutic agent or a targeting molecule having also therapeutic activity.

Abstract: A mammalian protein involved in receptor-mediated endocytosis specifically binds to phosphatidylinositol 3-kinase. More specifically it binds to the Bcr homology domain of the p85 subunit of phosphatidylinositol 3-kinase. Phathoidylinositol 3-kinase also binds to platelet derived growth factor receptor. Other receptors may also bind, including those for insulin, insulin-like growth factor-1, colony stimulating factor 1, nerve growth factor, hepatocyte growth factor, stem cell growth factor, and epidermal growth factor. Mitogenesis is the consequence of the binding and internalization of these growth factors. Inhibition of the process of receptor-mediated internalization inhibits mitogenesis.
