  • Publication number: 20220091122
    Abstract: The present invention relates to compounds and methods useful for the detection and treatment of disorders associated with frameshift mutations in coding microsatellite regions. The compounds and methods are applicable in cancers, especially of DNA mismatch repair deficient (MMR) sporadic tumors and HNPCC associated tumors. The compounds are useful for detection of disorders and in therapy such as immuno-therapy. The diagnostic methods relate to diagnosis and prognostic assessment of disorders associated with frameshift polypeptides originating from frameshift mutations in coding microsatellite regions of genes based on the detection of immunological entities directed against said frameshift polypeptides in body fluids.

  • Patent number: 11155878
    Abstract: The present invention relates to a method for discrimination of p16INK4a overexpressing metaplasias from neoplastic or preneoplastic p16INK4a overexpressing lesions by determination of the level of high risk HPV encoded gene-products such as e.g. HPV E2 and/or HPV E7 molecules in biological samples in the course of cytological testing procedures. The method thus enables for reduction of false positive results in the p16INK4a based detection of anogenital lesions in cytological testing procedures.

  • Publication number: 20210071267
    Abstract: The present invention relates to a method for improved diagnosis of dysplasias based on simultaneous detection of INK4a gene products and at least one marker for cell proliferation. Particularly the present invention provides a method for discriminating dysplastic cells over-expressing INK4a gene products from cells over-expressing INK4a gene products without being dysplastic by detection of a marker suitable for characterizing the proliferation properties of the respective cell. The characterization of the proliferation properties may comprise the detection of a marker or a set of markers characteristic for active cell proliferation and/or a marker or a set of markers characteristic for retarded or ceased cell proliferation. The method presented herein thus enables for a specific diagnosis of dysplasias in histological and cytological specimens.

  • Patent number: 10697966
    Abstract: This invention provides methods and kits for improved diagnosis of medically relevant conditions by solution based biochemical testing procedures performed in solutions of test samples. The invention provides a method to substitute the cell based morphological information contained within the cytological and/or histological data of the test sample by molecular information obtainable from the solution, wherein the original test sample is dissolved and thus enables for accurate and reproducible assessment of medically relevant diagnosis from dissolved test samples. The method according to the invention comprises the steps of determining the levels of one or more disease markers associated with the condition to be diagnosed, determining the level of one or more normalization markers suitable to substitute the information related to morphological aspects of the sample, comparing and/or combining the data of the disease and normalization markers, and assessing diagnosis of a medically relevant condition.

  • Patent number: 8728745
    Abstract: The present invention concerns a method for predicting the potential for aggressive growth and/or the risk to progress to high grade cancer for tumors in cell based detection procedures. In one aspect the invention concerns the detection of overexpression of cyclin-dependent kinase inhibitor gene products as a tool for predicting the progression risk and/or potential for aggressive growth of tumors. In a second aspect the invention concerns predicting the progression risk and/or potential for aggressive growth in tumors on the basis of the simultaneous co-detection of the presence of overexpression of cyclin-dependent kinase inhibitor gene products together with the expression of markers for active cell proliferation. Further the invention concerns preparations of probes for diagnosis namely for predicting the progression risk and/or the potential for aggressive growth of tumors.
