RIOK2-dependent transcriptional changes in primary human hematopoietic stem and progenitor cells (HSPCs)

Project description:Purpose: Illumina next-generation sequencing (NGS) has been used to interrogate the transcriptome profiling (bulk RNA-seq) of primary human HSPCs in the presence and absence of RIOK2. Primary human hematopoietic stem and progenitor cells (HSPCs) isolated from 3 different donors were genome edited to obtain knockdown (KD) and knockout (KO) of RIOK2. The genome edited HSPCs were then differentiated for 48 hours and their total RNA was isolated to perform cDNA synthesis and bulk RNA sequencing. The overall goal of this study was to investigate the global alterations in gene expressions with dose-dependent loss of RIOK2 in primary human HSPCs, that would expand our understanding of RIOK2-dependent transcriptomic changes involved in hematopoietic differentiation.

Expression Profiling of Primary Human Fetal and Adult Hematopoietic Stem/Progenitor Cells (HSPCs) and Differentiating Proerythroblasts (ProEs)

Project description:To facilitate comparative genomic analyses of human fetal and adult cells undergoing erythropoiesis, we employed a serum-free two-phase liquid culture system to expand and differentiate primary human CD34+ hematopoietic stem/progenitor cells (HSPCs) ex vivo. In this experimental context, highly enriched populations of stage-matched, differentiating, primary proerythroblasts (ProEs) were generated. We selected four time points (day 0, CD34+ HSPCs; day 3, 5, and 7, differentiating ProEs) that represented similar stages differentiation for gene expression profiling using microarrays. Primary maturing fetal or adult erythroblasts were generated ex vivo from CD34+ hematopoietic stem/progenitor cells (HSPCs) using a serum-free two-phase liquid culture system. Total RNA from primary fetal and adult HSPCs (day 0) and differentiating proerythroblasts (ProEs; day 3, 5, and 7) were extracted and used to hybridize to Affymetrix expression arrays using the HG-U133 Plus 2.0 platform.

RNA-seq transcriptional profiling in human primary fetal and adult CD34+ hematopoietic stem/progenitor cells (HSPCs) erythroid progenitor cells (ProEs)

Project description:Advances in sequencing-based genomic profiling present a new challenge of explaining how changes in DNA/RNA are translated into proteins linking genotypes to phenotypes. The developing erythroid cells require highly coordinated gene expression and metabolism, and serve as a unique model in dissecting regulatory events in development and disease. Here we compare the proteomic and transcriptomic changes in human hematopoietic stem/progenitor cells and lineage-committed erythroid progenitors, and uncover pathways related to mitochondrial biogenesis enhanced through post-transcriptional regulation. Two principal mitochondrial factors TFAM and PHB2 are tightly regulated at the protein level and indispensable for mitochondria and erythropoiesis. mTORC1 signaling is progressively enhanced to promote translation of mitochondrial proteins during erythroid specification. Genetic and pharmacological perturbation of mTORC1 or mitochondria impairs erythropoiesis. Our studies suggest a new mechanism for regulation of mitochondrial biogenesis through mTORC1-mediated protein translation, and may have direct relevance to the hematological defects associated with mitochondrial diseases and aging.

Foetal and adult HSPCs - Comprehensive Proteomic Characterization of Ontogenic Changes in Hematopoietic Stem and Progenitor Cells

Project description:Haematopoietic stem and progenitor cells (HSPCs) in the foetus and adult possess distinct molecular landscapes that regulate cell fate and change their susceptibility to initiation and progression of haematopoietic malignancies. The proteomic programs that govern these differences remain elusive. In this study, we have utilized a mass spectrometry-based quantitative proteomics approach to comprehensively describe and compare the proteome of foetal and adult HSPCs. We found that the proteome of foetal HSPCs is relatively simple, characterized by proteins involved in cell cycle and cell proliferation, while their adult counterparts are defined by a larger set of proteins that are involved in more diverse cellular processes. These adult characteristics include an arsenal of proteins important for viral and bacterial defence, as well as protection against ROS-induced protein oxidation. Our further analyses of Type I interferon signalling shows that foetal HSPCs are sensitive to Interferon a (IFNa), which impairs their production of mature lymphoid cells, whereas stimulation with IFNa to the pregnant mother enhances the production of early progenitors from foetal HSCs. Our results provide new and important insights into the molecular landscape of foetal and adult haematopoiesis that advance our understanding of normal and malignant haematopoiesis during foetal and adult life.

Gene Expression Profiling of HEMGN-/- and WT HSPCs sorted from primary recipients 6h after transplantation (early homing cells)

Project description:To clarify the mechanism through which HEMGN (also known as EDAG in human) controls the survival and functions of hematopoietic stem and progenitor cells (HSPCs) under transplantation stress, we compared the transcriptome of Hemgn-/- and WT HSPCs isolated from primary recipients 6h after transplantation by RNA sequencing (RNA-Seq).

RUNX1-ETO (RE) murine hematopoietic stem/progenitor cells (HSPCs) treated with GM-CSF

Project description:GM-CSF signaling was previously reported to have a negative effect on a murine model of (8;21)-induced leukemia. Gene expression profiling of MigR1 (Mig) control and RUNX1-ETO (RE), the oncofusion protein generated from t(8;21), murine Lin-/c-Kit+ hematopoietic stem/progenitor cells (HSPCs) was conducted to further elucidate the mechanisms mediating the negative effect induced by GM-CSF signaling in t(8;21) cells,

Ceramide-dependent vesicle secretion modulates the integrated stress response in hematopoietic stem cells

Project description:Cellular crosstalk within the bone marrow niche maintains hematopoietic stem and progenitor cell (HSPC) integrity and safeguards lifelong blood and immune cell production. Deeper understanding of reciprocal niche signals governing crucial properties of HSPCs is relevant to the pathophysiology of blood disorders and improving HSPC transplantation. Extracellular vesicles (EVs) are key factors of the HSPC secretome, providing signals that regulate homeostasis and stemness. Here we demonstrate ex vivo blockade of ceramide-dependent vesicle secretion from HSPCs activates an integrated stress response (ISR), promoting downstream mTOR inhibition and metabolic quiescence. Crucially, ceramide-EV depletion leads to striking improvements in long-term transplantation. The aggregate findings link ceramide-dependent EV secretion and the ISR as a regulatory dyad guarding HSPC homeostasis and long-term fitness. Translationally, these data support exploration of ceramide inhibition during ex vivo maintenance of HSPCs for adoptive transfer.

BRAFV600E-induced transcriptional changes in cord blood-derived hematopoietic stem and progenitor cells

Project description:BRAFV600E is a recurrent mutation in the histiocytoic disorders Langerhans cell histiocytosis (LCH) and Erdheim Chester Disease (ECD). The mutation can be detected in committed monocytes/macrophages, dendritic cells, and hematopoietic stem and progenitor cells (HSPCs). Although the cell of origin that gives rise to these disorders is currently unknown, it was recently suggested that LCH and ECD arise from BRAFV600E-mutant HSPCs. To understand the underlying molecular mechanisms in HSPCs driving this phenotype, we introduced BRAFV600E into healthy human HSPCs using CRISPR/Cas9.
