mRNA profiles of hematopoietic stem or progenitor cells in bone marrow after 5-FU administration

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), 100 cells of HSCs were sorted. Moreover, after HSCs were cultured for 1day, 100 cells of phenotypic HSCs were sorted. These cells were subjected to mRNA sequence using Next-seq. The sequence reads that passed quality filters were analyzed by CLC genomic workbench.

Sca1+ macrophages activate hematopoietic stem/progenitor cells upon bone marrow stress. [scRNA-Seq]

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.

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), 12500 cells of HSCs were sorted. These cells were subjected to CUT&Tag-seq to analyze H3K27ac profile by using Next-seq. The sequence reads that passed quality filters were analyzed by Trimmomatic.

miRNA profiling data of mouse bone marrow samples four days post 5-FU treatment versus untreated controls

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%. 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.
