Methods and uses involving genetic aberrations of nav3 and aberrant expression of multiple genes

Abstract

The present invention relates to the fields of genetics and oncology and provides methods for detecting tumors as well as methods for treating patients and predicting the prognosis to a patient. Specifically, the present invention relates to a method of demonstrating the malignant character of a tumor or cell subpopulation in a subject, to a method of predicting a prognosis, to a method of treating a subject having a tumor with NAV3 copy number change and with over expression of at least one gene or gene product selected from specific lists, and to a method of selecting a treatment to a subject. The present invention also relates to uses of NAV3 gene or gene product and at least one gene and/or gene product selected from specific lists for demonstrating the malignant character of a tumor or cell sub-population, for predicting a prognosis to a subject, for selecting a treatment to a subject, and for cancer therapy in a subject having a tumor with NAV3 copy number change. Furthermore, the present invention also relates to a use of an antagonist, antibody or inhibitory molecule of at least one gene and/or gene product selected from specific lists for cancer therapy in a subject. Still, the present invention relates to a diagnostic kit comprising tools for detecting NAV3 copy number change in a biological sample and tools for detecting over expression of at least one gene or gene product selected from specific lists in a biological sample. The present invention also relates to a use of a diagnostic kit of the invention for demonstrating the malignant character of a tumor or cell subpopulation, for predicting a prognosis to a subject with a colorectal tumor, brain tumor or tumor of epidermal keratinocytes and for selecting a treatment to a subject with a colorectal tumor, brain tumor or tumor of epidermal keratinocytes.
