Abstract: The invention generally relates to the field of individualized medicine. It is a kind of liquid biopsy for individualizing and monitoring treatment in patients with tumors and for diagnosis of tumors. The invention relates to a method for identifying and characterizing subpopulations (subgroups) of circulating tumor cells (CTCs) in a population of CTCs in a biological sample, preferably in a blood sample of the patient. The invention also relates to the quantification of the respective subgroups of CTCs in the population of CTCs in the biological sample. The invention further relates to the use of the method for diagnosis and monitoring of tumors, decisions relating to treatment, surveillance of treatment and prognosis, in particular for all kinds of solid tumors. The invention further relates to the use of the identified CTC subgroups as biomarkers for diagnosis, prognosis and therapeutic treatment.

Abstract: The invention relates to specific marker proteins (biomarkers) for Hepatocellular carcinoma (HCC). The invention relates to a method for the diagnostic study of biological samples of a human for Hepatocellular carcinoma, the sample being studied for one or more proteins as a marker for Hepatocellular carcinoma, a concentration of the proteins which is elevated or decreased in relation to the healthy state indicating the presence of Hepatocellular carcinoma, a diagnostic test kit and a method of screening compounds effective in HCC.

Abstract: This invention relates to the treatment of hepatitis infections or hepatitis diseases, in particular hepatitis C. The invention more particularly relates to the use of an inhibitor and/or repressor of a nucleic acid molecule, especially gene, which is related to the proliferation and/or replication of hepatitis viruses, in particular hepatitis C viruses, in order to produce a medicament for preventing and/or curing hepatitis, in particular hepatitis C, as well as a pharmaceutical composition, preferably for preventing or treating hepatitis C diseases, said composition containing the repressor and/or inhibitor.

Abstract: The invention relates to a novel medical diagnostic method and treatment in conjunction with depression-inducing genes which are stimulated in particular by interferon. The invention relates in particular to the use of at least one nucleic acid molecule which induces depression and/or is associated with depression, in particular a gene and/or the DNA sequence thereof and/or the RNA sequence associated therewith, and/or a (poly)peptide encoded by the nucleic acid, for finding and/or providing a diagnostic method for detecting depression, or a medicament for the preventive and/or curative treatment of depression, and/or for determining the risk of developing depression, and/or for predicting the individual effects and/or side-effects of medicaments, in particular for treatment with interferon (for example, for the treatment of hepatitis).
