Publication number: 20110281270Abstract: 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.Type: ApplicationFiled: November 13, 2009Publication date: November 17, 2011Applicant: Erasmus University Medical Center RotterdamInventors: Erik Van Beers, Bas Wouters, Hendrik Rudolf Delwel, Peter Jacobus Maria Valk, Bob Löwenberg

Publication number: 20100191116Abstract: The invention relates to a method for quantification of a degree of obstruction in a liquid passageway, notably a male urethra. Data related to sonic waves generated by a liquid passing the obstruction may be accessed from a suitable file, or, alternatively may be directly obtained as a result of a measuring step 2. For determining the degree of obstruction of the urethra the measuring step 2 may be performed by arranging at least one sensor, notably a microphone, in the area of the perineum for detecting sonic waves generated by a liquid (urine) passing the obstruction. At the step 5 the power spectrum of the obtained data related to the sonic waves is calculated, after which a suitable feature 6a, 6b, or 6c representative of the power spectrum is selected. Preferable embodiments of the feature comprise a weighted average frequency of the power spectrum, a standard deviation of the power spectrum, or a skewness of the power spectrum, discussed above.Type: ApplicationFiled: June 16, 2008Publication date: July 29, 2010Applicants: Stichting Voor de Technische Wetenschappen, Erasmus University Medical Center RotterdamInventors: Tim Idzenga, Johannes Jacob Mient Pel, Robert van Mastrigt

Publication number: 20100003677Abstract: The present invention comprises a method method to identify tumor suppressor genes by detecting genes in a mouse retroviral insertion mutagenesis model which expression is inhibited by methylation of the viral insertion or the VIS-flanking gene. This is preferably accomplished by first randomly cutting the mouse genomic DNA, immunoprecipitating the methylated DNA and amplifying the VIS-flanking DNA by inverse PCR, optionally followed by cloning and sequencing of the amplicons. Next to the already known tumor suppressor genes Smad1 and Mad1-like, several putative tumor suppressor genes have been found. The tumor suppressing properties of these genes, as indicated in Table 3 also form part of the present invention.
