TranscriptomicsCDKN1B encoding the cyclin-dependent kinase inhibitor 1B (p27) is located in the minimally deleted region of 12p abnormalities in myeloid malignancies and its low expression is a favorable prognostic marker in acute myeloid leukemia
Alterations of the short arm of chromosome 12 (12p) occur in various hematological malignancies and ETV6 and CDKN1B, which are located on 12p, have been implicated as leukemogenic genes of interest. Design and Methods: We selected 7 patients with myeloid malignancies and small 12p deletions by FISH ...

TranscriptomicsMultilineage dysplasia does not influence prognosis in patients with CEBPA mutated AML supporting the WHO proposal to classify these patients as a unique entity
By WHO 2008, CEBPA-mutated AML became a provisional subentity, but it remains to be clarified how CEBPAmut AML with multilineage dysplasia (MLD; ?50% dysplastic cells in 2-3 lineages) but no other MDS-related feature should be classified. We investigated 108 CEBPAmut AML (15.7-87.6 years) for the im...

TranscriptomicsEZH2 mutations can be detected in 23% of PICALM-MLLT10 (CALM-AF10) positive acute leukemias
Interest focuses on genes encoding histone demethylases in hematologic malignancies, such as EZH2 (enhancer of zeste homolog 2). EZH2 mutations were recurrently observed in lymphomas and chronic myeloid malignancies, but data in acute leukemias are limited. We investigated 13 PICALM-MLLT10 (=CALM-AF...

TranscriptomicsMethylation of the Proximal, Distal and Core Promoter of CEBPA in 572 Cases with Normal Karyotpye AML and 44 with t(8;21) Disclosed Different Frequencies but no Impact on Prognosis
The clinical impact of aberrant CEBPA promoter methylation (PM) in AML is controversial discussed. The aim of this study was to clarify the significance of aberrant CEBPA PM with regard to clinical features in a cohort of 572 de novo AML with wildtype CEBPA and normal karyotype. The distal promoter ...
