(Submitter supplied) Pirin (PIR) is a putative transcriptional regulator whose expression is silenced in cells bearing the AML1/ETO and PML/RAR leukemogenic fusion proteins and is significantly repressed in a large proportion of acute myeloid leukemias. PIR expression increases during in vitro myeloid differentiation of primary hematopoietic precursor cells, and ablation of PIR in the U937 myelomonocytic cell line or in murine primary hematopoietic precursor cells results in impairment of terminal myeloid differentiation. more...

Analysis of U937 myelomonocytic cells depleted for Pirin. Pirin is silenced in cells with the acute myeloid leukemia-1 eight-twenty-one and promyelocytic leukemia/retinoic acid receptor leukemogenic fusion proteins. Results provide insight into the role of Pirin in myeloid differentiation.

(Submitter supplied) Chromatin accessibility is a key determinant of cell-type-specific gene expression. Here, we have investigated the chromatin architecture of different acute myeloid leukemia (AML) cells and the changes in accessibility when NB4 (APL) cells undergo the process of differentiation.

(Submitter supplied) PURPOSE: To evaluate frequency, biological features and clinical relevance of RUNX1 mutations in acute myeloid leukemia (AML). PATIENTS AND METHODS: Diagnostic samples from 945 patients (18 to 60 years) were analyzed for RUNX1 mutations. In a subset of cases (n=269) microarray gene expression analysis was performed. RESULTS: Fifty-nine RUNX1 mutations were identified in 53 of 945 (5.6%) cases, predominantly in exons 3 (n=11), 4 (n=10) and 8 (n=23). more...

(Submitter supplied) Recently, the p53-miR-34a network was identified to play an important role in tumorigenesis. As in acute myeloid leukemia with complex karyotype (CK-AML) TP53 alterations are the most common known molecular lesion, we further analyzed the p53-miR-34a axis in CK-AML with known TP53 status. Clinically, low miR-34a expression and TP53 alterations predicted for chemotherapy resistance and inferior outcome. more...

(Submitter supplied) Purpose: CEBPA mutations are found as either biallelic (biCEBPA) or monoallelic (moCEBPA). We set out to explore whether the kind of CEBPA mutation is of prognostic relevance in cytogenetically normal AML (CN-AML). Patients and Methods: 467 homogeneously treated CN-AML patients were subdivided into moCEBPA, biCEBPA and wildtype (wt) CEBPA patients. The subgroups were analyzed for clinical parameters and for additional mutations in the NPM1, FLT3 and MLL genes. more...

(Submitter supplied) We demonstrated that 3-Deazaneplanocin A (DZNep), a histone methyltransferase inhibitor, induce robust apoptosis in AML cells through increased ROS production and ER stress. We identified a core gene signature including TXNIP, a major redox control molecule which is crucial in DZNep-induced apoptosis.

(Submitter supplied) Ficolled AML-M0 sample gene expression profiles on Affymetrix HGU133Plus2.0 GeneChips. Acute myeloid leukemia (AML) classified as FAB-M0 is defined as a subtype with minimally differentiated morphology. Here we investigated by gene expression (GEP) profiling whether AML-M0 cases should be considered as one or more unique molecular subgroups that discriminates them from other AML patients. By applying GEP and subsequent unsupervised analysis of 35 AML-M0 samples and 253 previously reported AML cases, we demonstrate that AML-M0 cases express a unique signature. more...

(Submitter supplied) High VEGFC mRNA expression of AML blasts is related to increased in vitro and in vivo drug resistance. The prognostic significance of VEGFC on long-term outcome and its associated gene expression profiles remain to be defined. We studied the effect of VEGFC on treatment outcome and investigated gene expression profiles associated with VEGFC using microarray data of 525 adult and 100 pediatric AML patients. more...

(Submitter supplied) The pretreatment karyotype of leukemic blasts is currently the key determinant in therapy decision-making in acute myeloid leukemia (AML). However, approximately fifty percent of AML patients, often carrying a normal karyotype, are currently unclassifiable based these established methods. Gene expression profiling has proven to be valuable for risk stratification of AML. The gene expression profiles of AML samples of two independent cohorts (n=247 and n=214) were determined using Affymetrix U133Plus2.0 GeneChips: all Samples below 4000 are in the training cohort; all Samples higher than 4000 are in the validation cohort. more...
