RNA-seq study on mouse bone marrow HSPC cells isolated from Arid2 conditional knockout and control mice.

ABSTRACT: We isolated lineage negative, cKit+, Sca1+ hematopoietic stem and progenitor cells from mouse bone marrow from Arid2fl/fl:MxCre+ (knockout) and MxCre+ (control) mice. Mice were injected with pIpC 6 weeks prior to isolation of LSK cells. Total RNA was isolated followed by mRNA selection. cDNA libraries were generated and NextGen Sequencing was performed.

RNA-seq study on mouse bone marrow leukemia cells isolated from secondary transplant recipients receiving conditional knockout Arid1b or Arid2 MLL-AF9 cells

Project description:We isolated whole bone marrow leukemia cells from moribund secondary transplant recipients receiving VavCre+ (control), Arid1b fl/fl VavCre+ (knockout), Arid2 fl/fl VavCre+ (knockout), MxCre+ (control), Arid1b fl/fl MxCre+ (knockout), or Arid2 fl/fl MxCre+ (knockout) primary MLL-AF9 cells. Mice receiving MxCre+ (control), Arid1b fl/fl MxCre+ (knockout), or Arid2 fl/fl MxCre+ (knockout) MLL-AF9 cells were injected with pIpC 21 days post transplant. Total RNA was isolated followed by mRNA selection. cDNA libraries were generated and NextGen Sequencing was performed.

Gene-expression changes resulting from loss of the mTORC1 component Raptor in murine hematopoietic stem and progenitor cell-enriched populations (HSPC)

Project description:We investigated the role of mTORC1 in murine hematopoiesis by conditionally deleting the Raptor gene in murine hematopoietic stem cells. We observed mutliple alterations evoked by Raptor loss in hematopoiesis and profiled gene-expression alterations induced by raptor loss in Flt3-Lin-Sca1+cKit+ hematopoietic stem and progenitor enriched cell populations, 5 weeks post Raptor deletion. Flt3-Lin-Sca1+cKit+ cells were flow sorted from mice containing homozygous floxed alleles for exon 6 of the Raptor gene in the presence (MT group) or absence (WT group) of the MxCre transgene, which was induced with injections of mice with pIpC 5 weeks before cell isolation.

Gene expression data from mouse hemopoietic stem cells (LSKs), promyelocytes, myelocytes and granulocytes.

Project description:Differentiation of hemopoietic stem cells into granulocytes is characterized by distinct changes in the transcriptome. We analyzed mRNA expression in primary murine myeloid cells at four successive stages of hemopoietic differentiation; Lin- Sca1+ cKit+ stem/progenitor cells (LSKs), promyelocytes, myelocytes and granulocytes. Using fluorescence‚Äìactivated cell sorting, we isolated primary murine myeloid cells at four successive stages of hemopoietic differentiation; Lin- Sca1+ cKit+ stem/progenitor cells (LSK), promyelocytes, myelocytes and granulocytes.

RNA-seq profiling of HSC, MPPs and HPC-1s from Phf6-deleted and Phf6-intact mice

Project description:The study profiled the effect of Phf6 deletion on gene expression in hematopoietic stem cells (HSCs), multipotent progenitor cells (MPPs) and hematopoietic progenitor cells (HPC-1). Phf6lox/Y;Tie2-creTg/+ mice were prepared on a C57BL/6 background so that Phf6 deletion could be selectively mediated by Tie2-cre. Cell populations were sorted from bone marrow samples using standard surface markers (Lin–SCA1+cKIT+(LSK) CD150+ CD48– for HSCs, Lin–SCA1+cKIT+(LSK) CD150– CD48– for MPPs and Lin–SCA1+cKIT+(LSK) CD150- CD48+ for HPC-1 cells). Phf6 intact and Phf6-delected cells of all three types were profiled by paired-end RNA-seq using an Illumina NextSeq 500 sequencer. RNA-seq libraries were prepared from the HPC-1 samples used a standard Illumina TruSeq library protocol whereas the libraries for the HSC and MPP samples used a SMART-seq ultra low input kit for cDNA synthesis and amplification. Statistical analysis of the TruSeq and SMART-seq samples was undertaken separately.

Expression data of Hematopoietic progenitor and stem cells after 18h of culture with or without extracellular vesicles secreted by AFT stromal cells

Project description:Hematopoietic progenitor and stem cells from bone marrow have been sorted by FACS (LSK, Lineage -, Sca1 + and cKit +) and co-culture during 18h without cytokines with or without extracellular vesicles (EV) secreted by AFT stromal cells. We used microarray to detail the modification of gene expression level of LSK cells after contact with AFT Evs

DNA damage-induced HSPC failure depends on ROS accumulation downstream of IFN-1 signaling and Bid mobilization

Project description:Targeted mouse mutants with inactivated Mixed-Lineage-Leukemia-5 (Mll5, MGI:1924825) alleles exhibit numerical, cell cycle and functional abnormalities in their hematopoietic stem and progenitor cell (HSPC) compartments, including hyper-proliferation of otherwise quiescent hematopoietic stem cells, lack of long-term reconstitution potential and profound radiation sensitivity. Most of the HSPC defects are secondary to increased levels of DNA damage and intracellular accumulation of reactive oxygen species (ROS). To obtain first insights into underlying molecular mechanisms, we performed Affymetrix gene chip analysis using total RNA isolated from FACS-sorted Lin-Sca1+Kit+ (LSK) cells of Mll5+/+ and Mll5-/- mice, both with and without prior long-term treatment with the ROS quencher N-Acetyl-L-Cysteine (NAC). As key finding, microarray data revealed elevated hybridization signals for several transcripts of known or putative IFN-1 target genes in LSK cells from Mll5-/- mice irrespective of NAC-treatment. In fact, comprehensive gene set enrichment analysis identified a number of gene sets closely associated with interferon responses that were significantly affected in Mll5-/- LSK cells. RNA was isolated from FACS-sorted Lin-Sca1+Kit+ (LSK) cells of Mll5+/+ and Mll5-/- mice, both with and without prior long-term treatment with the ROS quencher N-Acetyl-L-Cysteine (NAC)

Genome wide chromatin accessibility of Helios null hematopoietic stem and progenitor cells

Project description:This experiment aimed to determine Helios contribution in chromatin accessibility in hematopoietic stem and progenitor cells. Thus, we examined the change in chromatin accessibility in purified hematopoietic stem cells (LSK, Lin-Sca1+ckit+) from 10 weeks old WT and Helios deficient mice using the ATAC-seq approach. We found that Helios null LSK an affected Open Chromatin Region (OCR) landscape, overall in the proximity of genes regulating platelets functions.
