Project description:We investigated the contribution of NOX-2 to redox balance, mitochondrial respiration, and glycolytic compensation in lineage-negative Sca-1⁺c-Kit⁺ (SKL) bone marrow stem cells from wild-type (WT) and NOX-2 knockout (NOX2-KO) mice. Proteomic profiling identified differentially expressed proteins involved in hypoxic response, glycolysis, and oxidative stress adaptation between WT and NOX2-KO SKL cells.
Project description:Loss of polycomb-group gene Ezh2 causes activation of fetal gene signature in adult mouse bone marrow (BM) hematopoietic stem and progenitor cells (HSPCs). Ezh2 directly represses fetal-specific let-7 target genes, including Lin28, thereby cooperates with let-7 microRNAs in silencing fetal gene signature in BM HSPCs. We purified Lineage-Sca-1+c-Kit+ (LSK) HSPCs from E14.5 FL and adult BM and subjected them to microarray analysis.
Project description:We performed RNA sequencing analyses of adult mouse bone marrow lineage-negative, Sca-1-positive, and c-kit-positive (LSK) hematopoietic stem/progenitor cell population. Especially, we investigated gene expression profiling of LSK cells before and after haloperidol treatment.
Project description:We performed RNA sequencing analyses of adult mouse bone marrow lineage-negative, Sca-1-positive, and c-kit-positive (LSK) multipotent progenitor cells in wildtype and Drd2 Drd3 double knockout mice
Project description:We found PAD4, which is one of the transcriptional co-regulator by histone modification, was highly expressed in lineage-, Sca-1+, c-kit+ (termed as LSK) cells of mouse bone marrow. To find the target genes which are regulated by PAD4 in LSK cells, we analyzed gene expression in PAD4-deficient mouse as compared with wild-type mouse.
Project description:The study was a comparison of gene expression using RNA-seq. We analyzed the stem and progenitor cells from WT and Vav-cre+ Tet2fl/fl Flt3-ITD (T2F3) mice. We isolated stem cells LSK (lin- sca+ kit+) and granulocyte-macrophage progenitors GMP (lin- sca- kit+ fcgr+ cd34+) cells from bone marrow. Comparisons were made across genotypes WT vs. T2F3 and cell types LSK vs. GMP.
Project description:By tracing the VE-cadherin expression in the newborn bone marrow hematopoietic LSK (lineage minus/Sca-positive/Kit-positive) cells, we demonstrated that the late foetal/newborn BM hemogenic endothelial cells produce a small cohort of hematopoietic stem and progenitor cells (HSPCs) capable of circulating and colonizing the secondary haematopoietic organs. Phenotypic and functional analyses disclosed that BM endothelium-derived HSPCs are mainly Multipotent Progenitors (MPPs) and a few Hematopoietic Stem Cells. We used microarrays to detail the global programme of gene expression underlying the endothelial origin of LSK cells in the newborn bone marrow.
Project description:LSKs(lineage-, Sca-1+, c-kit+ cells) in bone marrow from wild type (WT) and MC5R-knockout (KO) mice after after irradiation were isolated to explore the differentially expressed genes by RNA-seq.
