摘要:
A method of inhibiting growth of tumor cells which overexpress a growth factor receptor or growth factor by treatment of the cells with antibodies which inhibit the growth factor receptor function, is disclosed. A method of treating tumor cells with antibodies which inhibit growth factor receptor function, and with cytotoxic factor(s) such as tumor necrosis factor, is also disclosed. By inhibiting growth factor receptor functions tumor cells are rendered more susceptible to cytotoxic factors.
摘要:
The present invention relates to the novel family of receptor tyrosine kinases, herein referred to as MCK-10, to nucleotide sequences and expression vectors encoding MCK-10, and to methods of inhibiting MCK-10 activity. The invention relates to differentially spliced isoforms of MCK-10 and to other members of the MCK-10 receptor tyrosine kinase family. Genetically engineered host cells that express MCK-10 may be used to evaluate and screen drugs involved in MCK-10 activation and regulation. The invention relates to the use of such drugs, in the treatment of disorders, including cancer, by modulating the activity of MCK-10.
摘要:
A method of treating a human patient via active immunotherapy comprising administrating an effective amount of extracellular portion of human HER2 receptor to the patient wherein the method provokes a cell-mediated immune response to HER2 receptor in the patient treated therewith.
摘要:
The present invention relates to TKA-1 polypeptides, nucleic acids encoding such polypeptides, cells, tissues and animals containing such nucleic acids, antibodies to such polypeptides, assays utilizing such polypeptides, and methods relating to all of the foregoing. Methods for treatment, diagnosis, and screening are provided for TKA-1 related diseases or conditions characterized by an abnormal interaction between a TKA-1 polypeptide and a TKA-1 binding partner.

摘要:
The present invention relates to cell lines useful for the screening and identification of compounds that by modulating phosphotyrosine phosphatase activity, modulate insulin receptor type tyrosine kinase mediated signal transduction. Genetically engineered cells expressing IR in culture overcome the effect of insulin on morphology and adhesion when they are also coexpressing RPTP.alpha. or RPTP.epsilon.. Such engineered cell lines may be used to screen and identify non-toxic compounds that could elicit or modulate insulin signal transduction even in the absence of insulin.

摘要:
The present invention concerns compounds which can inhibit platelet derived growth factor receptor (PDGF-R) activity, preferably such compounds also inhibit the activity other members of the PDGF-R super family and are selective for members of the PDGF-R super family. The PDGF-R super family includes PDGF-R and PDGF-R related kinases Flt, and KDR. The featured compounds are active on cell cultures to reduce the activity of the PDGF-R and preferably one or more PDGF-R related kinases. An example of a featured compound, A10 (see FIG. 1a), and its ability to inhibit growth of tumor cells in vivo is described below. Using the present application as guide other compounds able to inhibit PDGF-R and preferably Flt and/or KDR can be obtained. Such compounds are preferably used to treat patients suffering from cell proliferative disorders characterized by inappropriate PDGF-R activity.
摘要:
Monoclonal antibodies which bind to the extracellular domain of the HER2 receptor and inhibit growth of SK-BR-3 breast tumor cells, which overexpress HER2, are disclosed. The monoclonal antibodies can be used for in vitro assays for detecting a tumor characterized by amplified expression of HER2.
摘要:
A novel protein tyrosine phosphatase is the protein designated PTP 1D. The PTP 1D protein may be produced by recombinant means, for example using a nucleic acid construct encoding the protein as provided herein. Also disclosed is an antibody specific for an epitope of PTP 1D, protein. Methods for identifying compounds which bind to a PTP 1D protein and inhibit or stimulate its enzymatic activity, pharmaceutical compositions comprising PTP 1D, and methods for treating a disease associated with PTP 1D protein using such compositions, are provided.
