(Submitter supplied) A doxycycline-inducible system was used to induce PU.1 expression in cultured myeloid cell lines. The parent cell line used was BN (Kamath et al., Leukemia 22:1214-1225, 2008). Induction of PU.1 expression was previously demonstrated to lead to cell cycle exit and decreased expression of cell cycle genes. The goal of this study is expression profiling of small RNAs in cells with reduced or elevated PU.1 expression.

(Submitter supplied) Knockdown of the transcription factor PU.1 (Spi1) leads to acute myeloid leukemia (AML) in mice. We examined the transcriptome of PU.1 knockdown hematopoietic stem cells (HSC) in the preleukemic phase by linear amplification and genome-wide array analysis to identify transcriptional changes preceding malignant transformation. Hierarchical cluster analysis and principal component analysis clearly distinguished PU.1 knockdown from wildtype HSC. more...

(Submitter supplied) Spi-B and PU.1 are highly related members of the E26-transformation-specific (ETS) family of transcription factors that have similar, but not identical, functions in B cell development. PU.1 and Spi-B are both expressed at high levels in lymphoma cell lines. We hypothesized that Spi-B and PU.1 occupy similar sites in the genome. To determine binding sites of Spi-B and PU.1, WEHI-279 mouse lymphoma cells were infected with retroviral vectors encoding 3XFLAG-tagged PU.1 or Spi-B. more...

(Submitter supplied) G1ME cells are GATA1-deficient murine bipotential megakaryocyte/erythrocyte progenitor cells derived from Gata1-negative murine ES cells. In order to assess the impact of GATA1 on gene regulation and cell differentiation, an expression construct was used to transiently produce high levels of GATA1. Cells transduced with this construct or a vector control were harvested at 18 and 42 hours, and gene expression was analyzed using Affymetrix MOE430 version 2 arrays.

(Submitter supplied) Ras mutations are commonly observed in Juvenile Myelomonocytic Leukemia (JMML) and Chronic Myelomonocytic Leukemia (CMML). JMML and CMML transform into Acute Myeloid Leukemia (AML) in about 10% and 50% of patients respectively. However, how additional events cooperate with Ras to promote this transformation are largely unknown. We show that absence of the Ubiquitin-Specific-peptidase 22 (USP22), a component of the SAGA chromatin-remodeling complex linked to cancer progression, unexpectedly promotes AML transformation in mice expressing oncogenic KrasG12D/+. more...

(Submitter supplied) Deletion of genes encoding the E26 transformation-specific (ETS) transcription factors, PU.1 and Spi-B, in B cells (CD19-CreDPB mice) leads to acute lymphoblastic leukemia at 100% incidence and with a median survival of 21 weeks. To identify pathways of leukemic transformation, we compared gene expression in leukemia cells from CD19-CreDPB mice (CD19-CreDPB B220- B-ALL) with B cells from Spi-B knockout (Control DB) or B cells from CD19-CreDPB mice (CD19-CreDPB B220+ B cell)

(Submitter supplied) Loss of chromosome 7 and del(7q) [-7/del(7q)] are recurring cytogenetic abnormalities in hematologic malignancies, including acute myeloid leukemia and therapy-related myeloid neoplasms, and associated with an adverse prognosis. We performed SNP array analysis on de novo and therapy-related myeloid neoplasms and identified a 2.17 Mb commonly deleted segment on chromosome band 7q22.1 containing CUX1, a gene encoding a homeodomain-containing transcription factor. more...

(Submitter supplied) The transcription factor PU.1 occupies a central role in controlling myeloid and early B cell development and its correct lineage-specific expression is critical for the differentiation choice of hematopoietic progenitors. However, little is known of how this tissue-specific pattern is established. We previously identified an upstream regulatory cis-element (URE) whose targeted deletion in mice decreases PU.1 expression and causes leukemia. more...

(Submitter supplied) The Ets family transcription factor PU.1 is essential for the development and maintenance of several hematopoietic lineages. In the thymus, PU.1 is expressed only in the early ETP/DN1, DN2a and DN2b stages of development. While PU.1 deletion in multipotent precursors leads to a complete block in T-cell development its function in the intrathymic stages in which it is expressed remains undetermined. The goal of this expression profiling study was to determine if PU.1 regulates the expression of T-lineage genes during the early stages of development. To do this, we generated the PU.1-Eng construct which expresses a fusion protein containing the DNA binding ETS domain of PU.1 (aas 159-260) fused to the obligate repressor domain (aas 1-298) of the Drosophila engrailed protein. The PU.1-ETS construct only expresses the ETS domain of PU.1 (aas 159-260) and serves as a control. Fetal liver precursors were isolated from e14.5 embryos and co-cultured with OP9-DL1 cells in the presence of IL-7 and Flt3L (5 ng/ml each) for 4 days to obtain FLDN1, DN2a and DN2b cells. These were infected with vector only, PU.1-ETS and the PU.1-Eng constructs and DN2 cells were sorted after 20 hours of infection. Total RNA was isolated from these cells and polyA+ fraction was used to prepare libraries for high throughput sequencing. Libraries prepared from 2 independent sets of samples were subjected to non-strand specific single-end sequencing.

(Submitter supplied) Downregulation of the hematopoietic transcription factor PU.1 in PU.1 low acute myeloid leukemia cells (AML) by novel heterocyclic diamidines or PU.1 inhibitors leads to decrease cell proliferation and apoptosis, representing a new therapeutic strategy for AML treatment. These inhibitors induces decreased PU.1 binding on its target sites, as well as deregulation in PU.1 canonical target genes We used microarray to identify the pathways deregulated after drug treatment.
