H3K9me3 Cut&Tag on hematopoietic stem cells sorted from mice 1 month after they were irradiated (2Gy total body irradiation = IR) or not (non irradiated = NIR) and with or without prior TNFa treatment (IR_TNF)

ABSTRACT: Analysis of the RNA-seq data performed in IR vs NIR hematopoietic stem cells show the loss of the TNF_via_NFKB signature. We showed that the loss of this signature could be associated with H3K9me3 loss at specific retrotransposable elements . To validate this association, we tested if TNFa treatment before irradiation was able to prevent IR-effect on H3K9me3 loss at retrotransposable elements. For this purpose, we treated mice with TNFa 1h before irradiation (IR_TNF) and performed H3K9me3 cut&tag experiments on hematopoietic stem cells 1 month after irradiation and compared them to hematopoietic stem cells sorted from non irradiated mice (NIR) and from non-treated irradiated mice (IR).

H3K9me3 ChIP-seq on hematopoietic stem cells sorted from mice 1 month after they were irradiated (2Gy total body irradiation = IR) or not (non irradiated = NIR)

Project description:We aim at understanding how ionizing radiations (IR) increase the risk of developing myeloid leukemia. We recently showed that IR leads to the derepression of retroelements. We demonstrated that retroelements expression in aged HSCs is regulated by the heterochromatin repressive histone mark H3K9me3. However, the mechanisms by which IR specifically triggers retroelements expression in HSCs are unknown. We hypothesized that retroelements derepression is due to IR-induced heterochromatin changes. To answer this question, we performed H3K9me3 ChIP-seq experiments in hematopoietic stem cells sorted from mice one month after they were irradiated and compared them to controls hematopoietic stem cells sorted from non-irradiated mice.

RNA-seq on hematopoietic stem cells sorted from mice 1 month after they were irradiated (2Gy total body irradiation = IR) or not (non irradiated = NIR)

Project description:We aim at understanding how ionizing radiations (IR) increase the risk of developing myeloid leukemia. We recently showed that IR leads to the derepression of retroelements. Retroelements are major contributors of gene regulatory networks. However, the impact of retroelements derepression on the HSC transcriptome and function remains to be addressed. We hypothesized that retroelements derepression is involved in HSC transcriptomic alterations. To answer this question, we performed RNA-seq experiments in hematopoietic stem cells sorted from mice one month after they were irradiated and compared them to controls hematopoietic stem cells sorted from non-irradiated mice.

Genome-Wide DNA Methylation Profiles in Hematopoietic Stem and Progenitor Cells Reveal Over-Representation of ETS Transcription Factor Binding Sites

Project description:DNA methylation is an essential epigenetic mark that is required for normal development. Knockout of the DNA methyltransferase enzymes in the mouse hematopoietic compartment reveals that methylation is critical for hematopoietic differentiation. To better understand the role of DNA methylation in hematopoiesis, we characterized genome-wide DNA methylation in primary mouse hematopoietic stem cells (HSC), common myeloid progenitors (CMP), and erythroblasts (ERY). Methyl Binding Domain protein 2 (MBD) enrichment of DNA followed by massively-parallel sequencing (MBD-Seq) was used to map genome-wide DNA methylation. Globally, DNA methylation was most abundant in HSC, with a 40% reduction in CMP, and 67% reduction in ERY. Only 3% of peaks arise during differentiation demonstrating a genome-wide decline in DNA methylation during erythroid development. Analysis of genomic features revealed that 98% of promoter CpG islands are hypomethylated, while 20-25% of non-promoter CpG islands are methylated. Proximal promoter sequences of expressed genes are hypomethylated in all cell types, while gene body methylation positively correlates with gene expression in HSC and CMP. Elevated genome-wide DNA methylation in HSC and the positive association between methylation and gene expression demonstrates that DNA methylation is a mark of cellular plasticity in HSC. Utilizing de novo motif discovery we identified overrepresented transcription factor consensus binding motifs in methylated sequences. Motifs for several ETS transcription factors, including GABPalpha and ELF1 are overrepresented in methylated regions. Our genome-wide survey demonstrates that DNA methylation is markedly altered during myeloid differentiation and identifies critical regions of the genome and transcription factor programs that contribute to hematopoiesis.

FACS-sorted cells from Young Adults Vaccinated with Influenza TIV or LAIV Vaccines during 2008/09 Flu Season

Project description:Systems vaccinology has emerged as an interdisciplinary field that combines systems wide measurements and network and predictive modeling applied to vaccinology. Here we used the systems vaccinology approach to study the molecular mechanisms underlying the innate responses to the trivalent inactivated influenza (TIV) and live attenuated influenza (LAIV) vaccination in humans, and to identify early gene signatures that predict the magnitude of the antibody responses to influenza vaccination. During the 2008 influenza season, healthy adults were vaccinated with TIV (6 vaccinees) or LAIV (6 vaccinees), and blood samples isolated at day 0 and at day 7 post-vaccination. Cell subsets (B cells, Monocytes, mDCs and pDCs) were FACS-sorted from frozen PBMCs. Microarrays were performed using amplified total RNA.

Single cell RNA sequencing of chronic myelomonocytic leukemia stem cell

Project description:Chronic myelomonocyticleukemia (CMML) is a clinically heterogeneous stem cell malignancy with overlapping features of myelodysplasiaand myeloproliferation. CMML is further subclassified according to percentage of leukemic blasts present in blood or bone marrow, reflecting its intrinsic tendency to progression towards acute myeloid leukemia. Over 90% of CMML patients carry founding mutations in epigenetic and/or splicing genes, which typically involve the primitive stem cell compartment. Thus, transcriptional dysregulation at the stem cell level is likely fundamental to disease onset and progression. However, the critical early hematopoietic stem and progenitor cell (HSPC) subpopulation has not been studied in CMML. We performed single cell RNA sequencing on>6,800 Lin-CD34+CD38-primitive HSPCs from seven CMML patients and three healthy controls. We found substantial inter-and intra-patient heterogeneity, with CMML stem cells displaying distinct transcriptional programs, differentiation potential and cellular signaling pathway priming. Pseudotime analyses revealed that CMML-1/CMML-2 HSPCs have distinct cellular trajectories, indicating that transformation events initiate early within the hematopoietic hierarchy and suggesting against a simple linear clonal evolution dynamic in acute leukemic transformation. We further identified several transcription factors uniquely active in distinct sample subsets. Together our findings provide novel insights into the CMML stem cell compartment, revealing an unexpected degree of transcriptional and subclonal heterogeneity and highlighting early mediators of disease initiation and transformation, of potential translational importance

Paired scRNAseq of the and non-hematopoietic and the immune microenvironment of aspirates from newly diagnosed Multiple Myeloma patients versus non-cancer controls

Project description:By generating a paired single cell RNA-sequencing database of the tumor niche from 10 newly diagnosed MM patients, we created a unique dataset allowing the in-depth analyses of stromal-immune interactions within the tumor microenvironment. Using this database, we identified the presence of inflammatory stromal fibroblasts in the bone marrow of Myeloma patients.The stromal inflammation was associated with NF-κB signaling, and sources of IL-1β or TNFα were specific immune subsets previously shown to be altered in MM, suggesting the presence of an immune cell-mediated feed-forward loop of bone marrow inflammation in MM. By tracking inflammatory signatures over time in individual patients undergoing first-line treatment using bulk RNA sequencing, we show that bone marrow inflammation is not reverted by successful anti-tumor therapy (see related accession number), suggesting a role for stromal fibroblasts and bone marrow inflammation in disease persistence or relapse.
