Abstract: This invention provides a method of treating a patient suffering from a tumor overexpressing N—CoR comprising administering to the patient a phosphatase ligand, alone or in combination with a retinoid receptor ligand, a histone deacetylase ligand, or both, in amounts effective to treat the patient. This invention also provides a method of inhibiting tumor growth in a patient suffering from a tumor overexpressing N—CoR. This invention further provides a method of identifying a compound or a mixture of compounds capable of inducing differentiation of cells of a tumor overexpressing N—CoR. This invention still further provides a method of determining the likelihood of successfully treating a subject suffering from a tumor overexpressing N—CoR. This invention also provides a method of assessing the likelihood that a patient is suffering from a tumor overexpressing N—CoR.

Abstract: The invention relates to the discovery of a novel tumor suppressor gene which is associated with multiple endocrine neoplasia type 1. The gene has been designated MEN1 and the gene product is menin. The absence of this protein and associated mutations in the corresponding gene have been identified in individuals suffering from multiple endocrine neoplasia type 1. The identification of this marker for multiple endocrine neoplasia type 1 has diagnostic uses as well as for gene therapy.

Abstract: A method of direct extraction of cellular material from a tissue sample which involves: forming an image field of cells of the tissue sample utilizing a microscope, identifying at least one zone of cells of interest from the image field of cells which at least one zone of cells of interest includes different types of cells than adjacent zones of cells, and extracting the at least one zone of cells of interest from the tissue sample. The extracted zone(s) of cells is subjected to analysis. The overall process of identifying, extracting, transporting, and analyzing the extracted zones(s) of cells can be fully automated.
