(Submitter supplied) We studied the variations of mRNA amounts after Flag-EVI1 or Flag expression in HeLa cells. Despites EVI1 discovery in 1988, its recognized role as a dominant oncogene in myeloid leukemia and more recently in epithelial cancers, only a few target genes were known and it was not clear why EVI1 was involved in cancer progression. Here we obtained the genomic binding occupancy and expression data for EVI1 in human cells. more...

(Submitter supplied) The product of the ecotropic virus integration site 1 (EVI1) gene, whose overexpression is associated with a poor prognosis in myeloid leukemias and some epithelial tumors, regulates gene transcription both through direct DNA binding and through modulation of the activity of other sequence specific transcription factors. Previous results from our laboratory have shown that EVI1 influenced transcription regulation in response to the myeloid differentiation inducing agent, all-trans retinoic acid (ATRA), in a dual manner: it enhanced ATRA induced transcription of the RARb gene, but repressed the ATRA induction of the EVI1 gene itself. more...

(Submitter supplied) To investigate whether and how expression of the oncogenic transcription factor EVI1 influences gene regulation by phorbol esters and vice versa, the human myeloid cell line U937 was transduced with an EVI1 expression vector or empty vector as a control. Cells were treated with 12-Otetradecanoylphorbol 13-acetate (TPA) or its solvent ethanol as a control. RNA was extracted and subjected to gene expression microarray analysis.

(Submitter supplied) Background: The transcription factor EVI1 regulates cellular proliferation, differentiation, and apoptosis, and contributes to an aggressive course of disease in myeloid leukemias and other malignancies. Notwithstanding, knowledge about the target genes mediating its biological and pathological functions remains limited. We therefore aimed to identify and characterize novel EVI1 target genes in human myeloid cells. more...

(Submitter supplied) We hypothesized that DNA methylation distributes into specific patterns in cancer cells, which reflect critical biological differences. We therefore examined the methylation profiles of 344 patients with acute myeloid leukemia (AML). Clustering of these patients by methylation data segregated patients into 16 groups. Five of these groups defined new AML subtypes that shared no other known feature. In addition, DNA methylation profiles segregated patients with CEBPA aberrations from other subtypes of leukemia, defined four epigenetically distinct forms of AML with NPM1 mutations, and showed that established AML1-ETO, CBFb-MYH11 and PML-RARA leukemia entities are associated with specific methylation profiles. more...

(Submitter supplied) Overexpression of ecotropic viral integration site 1 (EVI1) is associated with aggressive disease in acute myeloid leukemia (AML). Despite of its clinical importance, little is known about the mechanism through which EVI1 confers resistance to antileukemic drugs. Here, we show that a human myeloid cell line constitutively overexpressing EVI1 after infection with a retroviral vector (U937_EVI1) was partially resistant to etoposide and daunorubicin as compared to empty vector infected control cells (U937_vec). more...

(Submitter supplied) Evi1 is essential for proliferation of hematopoietic stem cells and implicated in the development of myeloid disorders. Particularly, high Evi1 expression defines one of the largest clusters in acute myeloid leukemia and is significantly associated with extremely poor prognosis. Improvement of the therapeutic outcome of leukemia with activated Evi1 is one of the most challenging issues. However, mechanistic basis of Evi1-mediated leukemogenesis has not been fully elucidated. more...

(Submitter supplied) Overexpression of the Ecotropic viral integration site 1 (EVI1) gene typically associates with aggressive forms of leukemia. Aberrant EVI1 expression is also detected in breast carcinoma but its role in this tumor type is largely unknown. In order to analyze its effects in breast cancer, shRNA knockdown was performed on MDA-MB-231 cells and gene expression compared in EVI1 knockdown versus corresponding control shRNA treated cells.

(Submitter supplied) The transcriptional regulator EVI1 has an essential role in early hematopoiesis and development. However, aberrantly high expression of EVI1 has potent oncogenic properties and confers poor prognosis and chemo-resistance in leukemia and solid tumors. To investigate to what extent EVI1 function might be regulated by posttranslational modifications, we carried out mass spectrometry- and antibody-based analyses and uncovered an ATM-mediated double phosphorylation of EVI1 at the carboxy-terminal S858/S860 SQS motif. more...

(Submitter supplied) We performed whole-genome gene expression profiling in Pik3cg-/- mice and subsequent gene ontology clustering of differentially expressed genes compared to wild type mice, in order to investigate the role of Pik3cg in platelet membrane biogenesis and blood coagulation. Pik3cg-deficient mice were obtained from sources previously described (T. Sasaki et al, 2000, Science 287, 1040-1046), backcrossed onto the C57BL/6J Jax genetic background for eight generations (B6J;129-Pik3cg-tm1Pngr) and then maintained as a closed colony by intercrossing from within the colony (C57BL/6J Jax contribution: 99.6%).
