Abstract: The present invention provides methods for identification of cancerous cells by detection of expression levels of TTK, as well as diagnostic, prognostic and therapeutic methods that take advantage of the differential expression of these genes in mammalian cancer. Such methods can be useful in determining the ability of a subject to respond to a particular therapy, e.g., as the basis of rational therapy. In addition, the invention provides assays for identifying pharmaceuticals that modulate activity of these genes in cancers in which these genes are involved, as well as methods of inhibiting tumor growth by inhibiting activity of TTK.

Abstract: This invention relates to novel human polynucleotides and variants thereof, their encoded polypeptides and variants thereof, to genes corresponding to these polynucleotides and to proteins expressed by the genes. The invention also relates to diagnostic and therapeutic agents employing such novel human polynucleotides, their corresponding genes or gene products, e.g., these genes and proteins, including probes, antisense constructs, and antibodies.

Abstract: Inhibitors of TSPAN-7 are provided that reduce the expression or biological activities of TSPAN-7 in a mammalian cell. TSPAN-7 inhibitors include antisense molecules, ribozymes, antibodies and antibody fragments, proteins and polypeptides as well as small molecules. TSPAN-7 inhibitors find use in compositions and methods for decreasing TSPAN-7 gene expression as well as methods for inhibiting proliferation of mammalian cells, including tumor cells, methods for decreasing the side effects of cancer therapy and methods for treating neoplastic diseases. Also provided are nucleic acids encoding a new member of the tetraspan family, TSPAN-7, and polypeptides encoded thereby.

Abstract: A polynucleotide sequence as shown in SEQ ID NO:1 is associated with metastatic potential of cancer cells, especially breast cancer cells. Methods are provided for determining the risk of metastasis of a tumor, by determining whether a tissue sample from a tumor expresses a polypeptide or mRNA encoded by a polynucleotide as shown in SEQ ID NO:1. Also provided are therapeutic methods and compositions.

Abstract: The present invention is based on the discovery of polynucleotides that represent genes that are differentially expressed in colon cancer, e.g., adenomatous polyp, colorectal carcinoma, high metastatic potential colon tumor and metastatic colon cancer. The invention features methods of identifying cells affected by such colon diseases by detection of a gene product encoded by such differentially expressed genes, as well as method of modulating expression of such gene products to effect therapy (e.g., to decrease growth and/or affect abnormal characteristics of cancerous or dysplastic colon cells).

Abstract: A human gene encoding a novel mitogen-activated (MAP) kinase kinase, MKK7, provides methods and reagents for treating a variety of MKK7-mediated disorders, such as ischemic heart disease, kidney failure, oxidative liver damage, respiratory distress syndrome, heat and radiation burns, septic shock, autoimmune disorders, and inflammatory diseases. MKK7 reagents can also be used to induce or prevent apoptosis.

Abstract: Modulators of NET-4 are provided that reduce the expression or biological activities of NET-4 or the expression of NET-4 mRNA in a mammalian cell. NET-4 modulators include antisense molecules, ribozymes, antibodies and antibody fragments, proteins and polypeptides as well as small molecules. NET-4 modulators find use in compositions and methods for decreasing NET-4 gene expression as well as methods for inhibiting the proliferation of mammalian cells, including tumor cells, and methods for treating neoplastic diseases.

Abstract: Isolated nucleic acid molecules comprising polynucleotide having sequences that encode human and Drosophila PAR-1 kinases. Also provided are proteins and polypeptides encoded by the nucleic acid molecules, methods of modulating PAR-1 expression and function, and methods of modulating the Wnt signaling pathway.

Abstract: A human gene encoding a novel cyclin-dependent kinase termed hPFTAIRE and its expression products can be used to provide reagents and methods for detecting migrating or metastasizing cells. Compositions and methods for treating proliferative disorders and neoplasia are also provided.

Abstract: The invention provides materials and methods for determining the metastatic potential of a cell and for identifying cancerous cells by determining the presence or absence of one or more expression products of at least one gene that is differentially expressed between normal cells, nonmetastatic cells, cells of low metastatic potential, and cells of high metastatic potential.

Abstract: A polynucleotide sequence as shown in SEQ ID NO:1 is associated with metastatic potential of cancer cells, especially breast cancer cells. Methods are provided for determining the risk of metastasis of a tumor, by determining whether a tissue sample from a tumor expresses a polypeptide or mRNA encoded by a polynucleotide as shown in SEQ ID NO:1. Also provided are therapeutic methods and compositions.
