Abstract: The invention is in the field of molecular medicine and provides methods for the treatment of acute myeloid leukemia. These methods are based on the observation that microRNA-9 and microRNA-9* are involved in the pathogenesis of the disease in that the overexpression of microRNA-9/9* block myeloid differentiation in vitro. More in particular, microRNA-9/9* were found to play a role in leukemic transformation in acute myeloid leukemia.

Abstract: The present invention relates to methods of genetic analysis for the classification, diagnosis and prognosis of acute myeloid leukemia (AML). The invention provides a method for producing a classification scheme for AML comprising the steps of a) providing a plurality of reference samples, the reference samples comprising cell samples from a plurality of reference subjects affected by AML; b) providing reference profiles by establishing a gene expression profile for each of the reference samples individually; c) clustering the individual reference profiles according to similarity; and d) assigning an AML class to each cluster. The invention further relates to a method for classifying the AML of an AML-affected subject, to a method for diagnosing AML in a subject, and to a method of determining the prognosis for an AML-affected subject.

Abstract: The invention is in the field of molecular diagnostics for cancer, in particular, for acute myeloid leukemia (AML). The invention provides methods for diagnosing AML patients with a favorable prognosis. We have found that not all AML patients carrying a CEBPA mutation may have a more favorable prognosis. We found that only the group with double mutations, i.e., biallelic mutations, have a particularly favorable prognosis. We also found a method that distinguishes mono-allelic CEBPA mutations from bi-allelic mutations.

Abstract: The present invention relates to murine genomic regions, identified by retroviral insertional tagging of mice as being involved in tumor development, in particular leukemia development, as well as human homologues thereof, and to the use of these genomic regions for the identification and development of anti-cancer drugs, such as small molecule inhibitors, antibodies, ribozymes, antisense molecules and RNA interference (RNAi) molecules, that are effective in reducing or eliminating the tumorigenic effects of genetic transformations in these genomic regions and/or eliminating the tumorigenic effects of expression products thereof. The invention further relates to these anti-cancer drugs and to their use as pharmaceutical reagents for the treatment of cancer, as well as to pharmaceutical compositions comprising one or more of said pharmaceutical reagents and to methods for the treatment of cancer using said pharmaceutical compositions, in particular to methods of gene therapy.
