Abstract: The present invention is related to a composition comprising a phosphodiesterase inhibitor, such as anagrelide or a salt thereof, for use in the treatment of a solid tumor, such as gastrointestinal stromal tumor (GIST) or a liposarcoma, which express phosphodiesterase 3 enzymes, in a human patient.

Abstract: The invention relates to a method for treating ERG-positive prostate cancer patients with an agent counteracting one or more ERG-associated genes and/or manipulating of one or more ERG-related pathways, optionally in combination with an androgen deprivation therapy. Furthermore, the invention concerns methods for screening prostate cancer patients which may benefit from said treatment, assessing the efficacy of a therapy for treating prostate cancer in a patient, assessing progression of prostate cancer in a patient, selecting an agent to be tested for usefulness in the treatment of prostate cancer, and for assessing prostate carcinogenic potential of an agent.

Abstract: The present invention relates to the fields of life sciences and biological processes. Specifically, the invention relates to microarrays and live cell based screening and molecular analysis. More specifically, the present invention relates to novel methods for the screening of the effects of a test compound on cells, for molecular analysis of the cells and for producing a microarray. The present invention also relates to cell arrays and the use of arrays for molecular analysis of the cells or for the screening of agents.

Abstract: The present invention provides compositions and methods of using the EPHB2 gene or its related signaling pathways to detect, prognosticate, assess the risk of, prevent, or treat cancers. Cancers amenable to the present invention include, but are not limited to, prostate cancer, breast cancer, and neuroblastoma. In one aspect, the present invention provides compositions which comprise an agent capable of eradicating or alleviating an abnormality in the EPHB2 gene or its related signaling pathways. This abnormality may cause or contribute to the development or progression of cancers. In another aspect, the present invention provides methods comprising detecting an abnormality in the EPHB2 gene or its related signaling pathways. The presence or absence of such an abnormality is indicative of the risk or disease status of cancer in a person of interest.

Abstract: An array-based technology facilitates rapid correlated gene copy number and expression profiling of a very large number of human tumors. Hundreds of cylindrical tissue biopsies (diameter 0.6 mm) from morphologically representative regions of individual tumors can be arrayed in a single paraffin block. Consecutive sections from such arrays provide targets for parrallel in situ visualization and quantitation of DNA, RNA or protein targets. For example, amplifications of six loci (mybL2, erbB2, Cyclin-D1, myc, 17q23 and 20q13) were rapidly determined by fluorescence in situ hybridization from 372 ethanol-fixed breast cancers. Stratification of tumors by estrogen receptor and p53 expression data revealed distinct patterns of gene amplification in the various subgroups of breast cancer that may have prognostic utility. The tissue array technology is useful in the rapid molecular profiling of hundreds of normal and pathological tissue specimens or cultured cells.

Abstract: A method and apparatus are disclosed for a high-throughput, large-scale molecular profiling of tissue specimens by retrieving a donor tissue specimen from an array of donor specimens, placing a sample of the donor specimen in an assigned location in a recipient array, providing substantial copies of the array, performing a different biological analysis of each copy, and storing the results of the analysis. The results may be compared to determine if there are correlations or discrepancies between the results of different biological analyses at each assigned location, and also compared to clinical information about the human patient from which the tissue was obtained. The results of similar analyses on corresponding sections of the array can be used as quality control devices, for example by subjecting the arrays to a single simultaneous investigative procedure. Uniform interpretation of the arrays can be obtained, and compared to interpretations of different observers.
