Project description:To understand the mechanisms through which JunB regulates Tregs-mediated immune regulation, we examined the global gene expression profiles in the JunB WT and KO Tregs by performing RNA sequencing (RNA-seq) analysis.
Project description:The experiment was designed to compare transcriptomic differences between WT and Ccr6 KO Tregs during activation. WT and Ccr6 KO Tregs, cells were isolated from mice and cultured in vitro for 3 days with activation using anti-CD3/CD28 beads. Total RNA was extracted using the Trizol method. Quantity and quality were assessed using a Thermo Scientific™ NanoDrop™ 2000/2000c Spectrophotometer. Novogene Corporation Inc prepared the RNA-seq 250-300 bp insert cDNA library. Illumina HiSeq platform PE150 sequencing was used for sequencing, yielding 20M raw reads/sample. Mus Musculus mm39 was used as the reference genome for alignment.
Project description:Genome-wide gene expression pattern of E47 KO versus WT HSCs from primary and secondary recipient mice were analysis using Agilent one-color micro-array analysis.
Project description:Genome-wide gene expression pattern of E47 KO versus WT HSCs from primary and secondary recipient mice were analysis using Agilent one-color micro-array analysis. Two replicates from 4 samples are analyzed. The sample from the WT mouse were set as their reference sample.
Project description:Gene profiling, using microarray technology, was used to identify differentially expressed genes in bone marrow-differentiated macrophages of Hem1 KO versus Hem1 WT mice
Project description:The adenosine 2A receptor (A2AR) is expressed on regulatory T cells (Tregs), but the functional significance is currently unknown. We compared the gene expression between wild-type (WT) and A2AR knockout (KO) Tregs and between WT Tregs treated with vehicle or a selective A2AR agonist. FACS-sorted GFP positive Tregs from WT or A2AR KO FoxP3GFP mouse spleen and lymph nodes were incubated 18 hr with vehicle (DMSO), a separate set of WT Tregs were incubated with the selective A2AR agonist ATL1222 10 nM (Dogwood Pharmaceuticals, Inc.) for 18 hr prior to RNA isolation.
Project description:High ploidy large cytoplasmic megakaryocytes (LCM) are critical negative regulators of hematopoietic stem cells (HSC) and are responsible for platelet formation. Using a mouse knockout model with normal megakaryocyte numbers but essentially devoid of LCM (MK-LCM KO), we demonstrated a pronounced increase in bone marrow HSC concurrent with endogenous mobilization and extramedullary hematopoiesis. When HSC isolated from a MK-LCM KO microenvironment were transplanted in lethally irradiated mice, the absence of LCM increased HSC in BM, blood and spleen. Severe thrombocytopenia was observed in animals with diminished LCM, although there was no change in megakaryocyte ploidy distribution. In contrast, WT HSC-generated LCM regulated a normal HSC pool and prevented thrombocytopenia. The present label-free quantitative LC-MSMS data was used to determine proteins that are differentially expressed in bone marrow cells of MK-LCM WT versus MK-LCM KO mice.
