Project description:To identify miRNAs that regulate hematopoietic response after 5-FU-induced injury, we analyzed miRNA expression changes in bone marrow cells from mice with or without 5-FU treatment. Global miRNA expression profiling of the 5-FU and untreated cohorts showed that 92 miRNAs (among 168 that passed the detection threshold) were significantly upregulated or downregulated, with false discovery rates < 5%.

Global miRNA expression profiling of the 5-FU and untreated cohorts showed that 92 miRNAs (among 168 that passed the detection threshold) were significantly upregulated or downregulated, with false discovery rates < 5%. Female 6wk-old C57Bl6/J mice were left untreated or given a single dose of 5-FU (150mg/kg). Four days post treatment whole bone marrow was isolated from each animal (n=3 for treated and n=5 for untreated controls) and lysed for total RNA using Trizol (Invitrogen). Samples were profiled for miRNA expression using a bead-based profiling methodology (Lu et al., 2008). Profiling data were normalized assuming equal total miRNA expression across samples. Differential miRNA expression was analyzed by studentM-bM-^@M-^Ys t-test and then calculated for false discovery rate using the Benjamini and Hochberg method.

Project description:Under stress hematopoiesis, previous studies have suggested the migration of hematopoietic stem cells (HSCs) from bone marrow (BM) to extramedullary sites such as spleen. However, there is little direct evidence of HSC migration from BM to spleen. Here, we induced myeloablation via 5-fluorouracil (5-FU) and showed the direct evidence of HSC migration from BM to spleen during hematopoietic regeneration via a photoconvertible fluorophore. We found that during hematopoietic regeneration, there were mechanistic differences for HSC migration during early (day 3 to 8) and late phase (day 11 to 14). During steady-state, HSCs preferentially migrated to BM rather than spleen, but during the early phase HSC migration to spleen predominated. Indeed, in the early phase, HSC mobilization from BM was induced in G-CSF-dependent manners, while HSCs in the late phase gained significantly enhanced cell-autonomous motility, which was independent of chemotaxis. Collectively, HSC migration was dynamically changed during hematopoietic regeneration.

Project description:Thiele2013 - Bone marrow hematopoietic cells
The model of bone marrow hematopoietic cells metabolism is derived from the community-driven global reconstruction of human metabolism (version 2.02, MODEL1109130000
).
This model is described in the article:
A community-driven global reconstruction of human metabolism.

Nature Biotechnology
Abstract:
Multiple models of human metabolism have been reconstructed, but each represents only a subset of our knowledge. Here we describe Recon 2, a community-driven,
consensus 'metabolic reconstruction', which is the most comprehensive representation of human metabolism that is applicable to computational modeling. Compared
with its predecessors, the reconstruction has improved topological and functional features, including ~2x more reactions and ~1.7x more unique metabolites. Using
Recon 2 we predicted changes in metabolite biomarkers for 49 inborn errors of metabolism with 77% accuracy when compared to experimental data. Mapping metabolomic
data and drug information onto Recon 2 demonstrates its potential for integrating and analyzing diverse data types. Using protein expression data, we automatically
generated a compendium of 65 cell type-specific models, providing a basis for manual curation or investigation of cell-specific metabolic properties. Recon 2 will
facilitate many future biomedical studies and is freely available at http://humanmetabolism.org/.

Project description:Purpose: The goals of this study are to elucidate the underlying mechanism for the regulation of HSC divisions. Methods: Before or after wild type (WT) mice were treated with 5-fluorouracil (5-FU), 15000 cells of HSCs were sorted. These cells were subjected to ATAC-seq using Next-seq. The sequence reads that passed quality filters were analyzed by FASTX-toolkit.

Project description:Although hematopoietic stem and progenitor cells (HSPCs) become activated in the cell-cycle status after chemotherapy to supply hematopoietic loss, the detailed mechanisms of activation remain unknown. Here we show that Sca1+ macrophages play a key role for bone marrow (BM) recovery through granulocyte-macrophage colony-stimulating factor (GM-CSF) secretion. By analyzing gene expression profiles of HSPCs lodged in 5-fluolouracil (5-FU)-treated mice, we found GM-CSF as a key proliferative signal. Sca1+ macrophages in BM after 5-FU treatment expressed high levels of GM-CSF. GM-CSF-knockout mice treated with 5-FU were lethal because of severe BM suppression. Up-regulation of Csf2 in Sca1+ macrophages by 5-FU was suppressed in MyD88-knockout mice, suggesting that TLR signaling via damage-associated molecular patterns caused by cell death is critical for up-regulation of Csf2. In 5-FU treated BM, majority of Sca1+ macrophages and transplanted HSPCs locate perivascular areas. These findings together indicate that Sca1+ macrophages induce HSPCs to proliferate through GM-CSF signaling in the stressed BM environments.
