Abstract: This invention relates to methods to diagnose colon cancer and other proliferative diseases. Gene 26#77 is identified herein as a novel oncogene. Methods are provided for diagnosing and treating a disease or disorder characterized by amplification of the 26#77 gene and/or overexpression of 26#77 gene products. The 26#77 gene is located on chromosome 20q13.2, a region whose amplification is associated with a poor cancer prognosis. The 26#77 gene is amplified and 26#77 RNA and protein are overexpressed in 60% of colorectal cancers.

Abstract: Methods and materials relating to the orphan receptor tyrosine kinase (ROR1) are described. ROR1 exhibits restricted tissue expression in normal adult tissue and is overexpressed in certain breast cancer subtypes. ROR1 provides a diagnostic and/or therapeutic target for breast cancers.

Abstract: The disclosure provided herein identifies and characterizes the domain in HER3 receptor that interacts with heregulin ligand. Typical embodiments of the invention disclosed herein include HER3 variant polypeptides having amino acid sequences which differ from the native HER3 polypeptide sequence and which have altered affinities for heregulin. Also disclosed herein are methods and materials for identifying compounds that bind to the heregulin binding domain in HER3 as well as methods and materials for modulating the interaction between HER3 and heregulin.

Abstract: The disclosure provided herein identifies and characterizes the domain in HER3 receptor that interacts with heregulin ligand. Typical embodiments of the invention disclosed herein include methods for identifying compounds which specifically bind the heregulin binding domain in HER3.

Abstract: The present invention relates to the identification of the H37 tumor suppressor gene and methods of diagnosing and treating a disease or disorder characterized by abnormal cellular proliferation, such as a tumor or cancer. Diagnosis is accomplished examining or monitoring cells for perturbations in H37 expression or function. Treatment is accomplished by inserting a host cell compatible H37 expression vector or an effective amount of H37 protein into a cell or cells in need of treatment.

Abstract: The invention disclosed herein improves upon existing tissue microarray technology by using frozen tissues embedded in tissue embedding compound as donor samples and arraying the specimens into a recipient block comprising tissue embedding compound. Tissue is not fixed prior to embedding, and sections from the array are evaluated without fixation or post-fixed according to the appropriate methodology used to analyze a specific gene at the DNA, RNA, and/or protein levels. Unlike paraffin tissue arrays which can be problematic for immunohistochemistry and for RNA in situ hybridization analyses, the disclosed methods allow optimal evaluation by each technique and uniform fixation across the array panel. The disclosed arrays work well for DNA, RNA, and protein analyses, and have significant qualitative and quantitative advantages over existing methods.

Abstract: The present invention provides human Her-2/neu overexpression modulated proteins (HOMPS) and polynucleotides encoding HOMPS polypeptides. The invention also provides HOMPS containing expression vectors and host cells, HOMPS antibodies and methods of producing HOMPS. In addition, the invention provides methods for generating, identifying and manipulating HOMPS.

Abstract: The present invention provides methods for obtaining genetic profiles of cancer cells in order to assess the status of a cancer in an individual. In addition, the present invention provides methods for inhibiting the growth of cancer cells that exhibit certain genetic profiles. These methods identify an important link between HER-2/neu overexpression and loss of growth inhibition by the TGF-&bgr; signaling pathway in cancer cells. Compositions as well as therapeutic and diagnostic methodologies based on this disclosure are provided.

The methods comprise providing a nucleic acid sample from a premalignant lesion in colorectal tissue from a human patient and contacting the sample with a nucleic acid probe that selectively hybridizes to a chromosomal region at 20q.

Abstract: Cellular components are quantitated using stained cell samples, computerized image analysis, and cellular standards, where the computerized image analysis value can be translated into the amount of the component per cell. The methodology is demonstrated with breast cancer cells and quantitation of the HER-2/neu gene. The quantitation is shown to have prognostic capability as to the future course of the disease.
