  • Patent number: 7514219
    Abstract: The present invention is a method distinguishing between head and neck squamous cell carcinoma and lung squamous cell carcinoma. In particular, a 10-gene classifier has been identified which can be used to distinguish between primary squamous cell carcinoma of the lung and metastatic head and neck squamous cell carcinoma. These genes include CXCL13, COL6A2, SFTPB, KRT14, TSPYL5, TMP3, KLK10, MMP1, GAS1, and MYH2. A panel of one or more of these genes, or proteins encoded thereby, can be used for early diagnosis and selection of an appropriate therapeutic treatment.

  • Publication number: 20070178044
    Abstract: A method for detecting DNA damage in a tissue sample involves contacting an immobilized biological sample with a labeled ligand which binds to human 53Bp1, and examining the immobilized sample for the presence of a label generated-detectable signal concentrated in foci in said sample. The presence of concentrated foci is indicative of DNA damage and the presence of diffuse signal is indicative of a normal sample. Diagnostic reagents contain a ligand that binds to human 53Bp1 associated with a detectable label. Diagnostic kits for detecting DNA damage in a biological sample contain such diagnostic reagents and signal detection components. Compositions that inhibit or antagonize the biological activity of 53Bp1 are identified by suitable assays, and are employed in methods of retarding the growth of a cancer cell.

  • Patent number: 7217570
    Abstract: An organotypic culture comprises an artificial stroma overlayed with epithelial cells isolated from a human colon or intestine. The stroma comprises a mixture of collagen and human fibroblasts isolated from a human colon or intestine. The culture contains a factor that binds the IGF-1 receptor, a factor that binds the EGF receptor, and a factor that binds the LIF receptor. These factors may be added exogenously to the culture via medium or may be expressed by various recombinantly engineered cell types in the culture. The organotypic culture can result in growth that is in situ-like or emphasizes other physiological or morphological states, depending on the balance of factors in the growth media. The organotypic culture may be used in methods for screening of therapeutic, carcinogenic, or growth enhancement factors, or for treating intestinal injuries by applying to the site of an injury the intact culture or the components thereof.

  • Patent number: 7176293
    Abstract: An isolated nucleic acid sequence of a mitotic checkpoint gene, chfr, encodes a Chfr protein having a Forkhead-associated domain and a Ring Finger. This protein is required for regulation of the transition of cells from prophase to metaphase during mitosis. The chfr nucleic acid and Chfr polypeptide are useful in diagnosing tumorigenic cells and in screening for drugs which can inhibit the activity of Chfr in a cancer cell, thereby rendering the cell more sensitive to additional anti-tumor therapies.

  • Publication number: 20060271309
    Abstract: A method of developing a gene expression profile indicative of the presence or stage of a selected a disease, disorder or genetic pathology in a mammalian subject employs penalized discriminant analysis with recursive feature elimination. A method of diagnosing a cancer in a mammalian subject includes the steps of examining a sample containing the subject's immune cells and detecting a variance in the expression of a statistically significant number of genes, e.g., at least 10 non-tumor genes from those same genes in a characteristic disease or healthy gene expression profile. A significant variance in expression of these genes when compared to a gene expression profile, preferably an average gene expression profile of a normal control, or significant similarities to an average gene profile of subjects with cancer, correlates with a specific type of cancer and/or location of tumor.

  • Publication number: 20060240494
    Abstract: A method for identifying a compound that has a biocidal effect against a selected organism involves screening from among known or unknown peptide or non-peptide molecules, a test molecule that binds selectively to a target sequence of a multi-helical lid of a heat shock protein of the organism. The binding of the test compound inhibits the protein folding activity of the protein. A specific embodiment of such a method is useful for identifying or designing a pharmaceutical or veterinary biocidal or antibiotic compound, preferably a pathogen and/or strain-specific compound. For this purpose, the compound does not bind to a heat shock protein that is homologous to the mammalian subject to be treated with the compound. Screening methods can encompass direct binding or competitive assays. Molecules or compounds identified by these methods are employed as biocides for pharmaceutical, veterinary, pesticide, insecticide and rodenticide uses, among others.

  • Publication number: 20060156419
    Abstract: A non-human mammalian model of an autoimmune disorder co-expresses a major histocompatibility (MHC) class II-restricted T cell receptor (TCR) and a selected peptide that binds to the TCR. The selected peptide is selectively expressed by MHC class II positive antigen presenting cells (APC) of the mammal. Models with high penetrance of disease are those in which the selected peptide is a MHC class II-restricted T cell determinant that specifically binds with high affinity to the TCR. Models with low penetrance of disease are those in which the selected peptide binds with low affinity to the TCR. These models, which may be transgenic mammals, are used in method for identifying diagnostic and therapeutic markers and targets characteristic of an autoimmune disorder.
