RNAseq of murine primary bone marrow cells transformed by an inducible Hoxa9-ER: time-course

Project description:Relative overexpression of HOXA9 is a key feature of aggressive AML (acute myeloid leukemia). Hoxa9 responsive genes were identified by nascent RNA sequencing (4-thio-uridine labeled RNA - sequencing) in samples of primary hematopoietic precursor cells from mice transformed by an tamoxifen inducible version of Hoxa9 (Hoxa9-ER). Samples were generated in the presence of active Hoxa9 (0h) and in a time series after Hoxa9 was inactivated at 8h, 16h, 24h, 48h, and 72h.

Gene expression changes after loss of Hoxa9 in transformed HSCs [HOXA9 RNA-seq]

Project description:Characterization of gene expression changes 72 hours after withdrawal of tamoxifen in murine hematopoietic progenitors transformed by Hoxa9-ER/Meis1 using RNAseq. In the presence of tamoxifen (4OHT), Hoxa9-ER localizes to the nucleus of cells allowing for transformation, while withdrawal of 4OHT (culture in EtOH) leads to loss of nuclear Hoxa9-ER. Loss of Hoxa9-ER leads to a decrease in cellular proliferation and differentiation along the myeloid lineage.

Time course of myeloid differentiation in the Lysozyme-GFP ER-HoxA9 cells following estradiol withdrawal

Project description:Lysozyme-GFP ER-HoxA9 cells were cultured in the presence of estradiol (active ER-HoxA9) or in the absence of estradiol (inactive ER-HoxA9). Samples were taken at 10 time points over a 120 hour time course of myeloid differentiation to examine those gene expression changes that accompany differentiation upon the release of HoxA9 differentiation arrest.

Identification of genome wide Hoxa9 binding sites in primary murine and human AML cells

Project description:Relative overexpression of HOXA9 is a key feature of aggressive AML (acute myeloid leukemia). Here we determined genome wide binding sites of Hoxa9 in primary murine cells transformed by Hoxa9 and in a human AML cell line. In addition global H3K4 monomethylation and H3K27acetylation levels were determined in cells transformed by an inducible Hoxa9-ER construct in Hoxa9-active conditions and 72h after Hoxa9 was inactivated.

Genome-wide co-occupancy of Hoxa9 and C/EBPα in Hoxa9/Meis1 transformed HSCs [ChIP-seq]

Project description:Identification of the genome-wide binding sites of Hoxa9 and C/EBPα in a murine myeloblastic cell line transformed by Hoxa9/Meis1. Over 50% of Hoxa9 binding sites are co-bound by C/EBPα, providing mechanistic insight into the requirement of C/EBPα for Hoxa9-mediated leukemogenesis. Additionally, genome-wide occupancy of H3K4 monomethylation and H3K27 trimethylation provide additional information on the functionality of Hoxa9/C/EBPα cobound loci.

Gene expression changes upon Mll1 knockout in NUP98-HOXA9 transformed murine LSKs

Project description:We report Illumina next generation RNA sequencing (RNAseq) of NUP98-HOXA9 in vitro transformed murine LSKs upon genetic deletion of Mll1. These gene expression data illustrate that Mll1 regulates Hoxa, Hoxb and Meis1 expression in NUP98-HOXA9 transformed murine BM cells.

Determination of HOXA1 and HOXA9 target genes with inducible HOX constructs

Project description:Target genes of HOXA1 and HOXA9 were determined with the help of inducible HOX-ER constructs. For this purpose bone marrow was harvested from C57BL/6 mice and c-Kit positive progenitors were enriched by magnetic sorting (MACS technology, Miltenyi, Germany). After retroviral infection by spinoculation the cells were plated for three rounds in methylcellulose. Subsequently cells were maintained in liquid culture in RPMI1640 supplemented with murine recombinant cytokines at 100ng/ml (stem cell factor) and 10ng/ml (IL-3, IL-6, granulocyte/macrophage-colony stimulating factor) as well as 100nM 4-hydroxy-tamoxifen (TAM) for HOX activation.<br><br>For microarray analysis 4 independent cell lines were created for each HOX construct. RNA was isolated from cells in the presence of TAM and 72h after withdrawal of the inductor. Pairs of RNA replicates were pooled and two +TAM as well as two -TAM duplicates per HOX gene were hybridized to Agilent44K mouse expression arrays. Array processing and evaluation was done commercially according to Agilent specifications by ImaGenes (now SourceBioScience), Berlin, Germany.
