Mouse primary T-ALL microRNA microarray

ABSTRACT: Primary mouse cells (CD4-CD8- (DN) and CD4+CD8+ (DP) thymus and T-ALL (early-stage - ES and late-stage - LS) and mouse T-ALL cell line M295 were assessed for microRNA expression For DN, DP, ES_T-ALL and LS_T-ALL cells, n=3 biological replicates were used. M295 is one 1 replicate

Gene expression analysis of thymocyte subsets

Project description:Mouse thymocytes can be classified into four major subsets based on expression of CD4 and CD8 co-receptors. CD4-CD8- (double negative, DN) cells become CD4+CD8+ (double positive, DP) cells following productive T cell receptor (TCR) beta chain rearrangement. A small proportion of DP cells are selected through interaction of clonal TCRalpha/beta and MHC self peptide complex expressed on thymic stromal cells. DP cell expressing MHC class I-restricted TCR become CD4-CD8+ cells, which will finally differentiate into cytotoxic T cells, while MHC class II restricted selection generates CD4+CD8- helper lineage T cells. We used microarrays to identify genes important for thymocyte differentiation and lineage determination by profiling gene expression in different thymocyte subsets. Mouse thymocytes were divided into four subsets based on CD4, CD8a, and TCRb expression and purified by flw cytometry. FACS purified DN (CD4-CD8a-TCRb-), DP (CD4+CD8a+), CD4SP (CD4+CD8a-TCRbhi) and CD8SP (CD4-CD8a+TCRbhi) populations were lysed in Trizol, and provided to the Genomics Core Facility of the Memorial Sloan-Kettering Cancer Center (MSKCC) for quality control, quantification, reverse transcription, labeling and hybridization to MOE430A 2.0 microarray chips (Affymetrix). Arrays were scanned per the manufacturer’s specifications for the Affymetrix MOE430v2 chip.

T-cell development

Project description:T cells develop from progenitors that migrate from the bone marrow into the thymus. Thymocytes are subdivided roughly as being double negative (DN), double positive (DP), or single positive (SP), based on the expression of the CD4 and CD8 coreceptors. The DN stage is heterogeneous and can be subdivided into four distinct subsets in mice based on the expression of CD44 and CD25. In human, three distinct DN stages can be recognized: a CD34+CD38−CD1a− stage that represents the most immature thymic subset and the consecutive CD34+CD38+CD1a− and CD34+CD38+CD1a+ stages. Human DN thymocytes mature via an immature single positive (ISP CD4+) and a DP stage into CD4+ or CD8+ SP T cells that express functional T cell receptors (TCR) and that exit the thymus. In this study, gene expression was measured in each of these nine stages.

Gene expression analysis of Ets1-/- CD4+ CD8+ thymocytes

Project description:We performed ChIP-Seq for hallmark TFs (Ets1, Runx1), histone modification marks (H3K4me1, H3K4me2, H3K4me3, H3K27me3, H3K36me3), total RNA Pol II, short RNA-Seq as well as nucleosome mapping mainly in murine Rag2 -/- thymocytes. We also performed ChIP-Seq for E47 as well as nucleosome mapping, gene expression microarray analysis in CD4+ CD8+ WT and Ets1-/- DP thymocytes. Overall, we find a key role for the transcription factor Ets1, contributing towards alpha beta T cell lineage commitment via differential transactivation of stage-specific genes orchestrated by dynamic, co-association -mediated chromatin remodeling, as well as transcription dependent generation of a specialized chromatin structure at the TCR beta locus. Genome-wide analysis via ChIP-Seq for Ets1, Runx1, total RNA Pol II binding, H3K4me1, H3K4me2, H3K4me3, H3K27me3, H3K36me3, short RNA-Seq, Mnase-Seq in murine Rag2 -/- thymocytes, ChIP-Seq for E47, Mnase-Seq and gene expression microarray analysis in DP thymocytes Gene expression analysis of Ets1-/- CD4+ CD8+ thymocytes

A discrete chromatin loop in the murine Tcra/Tcrd locus shapes the TCRδ and TCRα repertoires

Project description:The Tcra/Tcrd locus undergoes V(D)J recombination in CD4−CD8− double-negative (DN) thymocytes and CD4+CD8+ double-positive (DP) thymocytes to generate diverse TCRδ and TCRα repertoires, respectively. Here we reveal a Tcra/Tcrd locus chromatin interaction network in DN thymocytes that is formed by interactions between CTCF-binding elements (CBEs). Disruption of a discrete chromatin loop encompassing the Dδ, Jδ and Cδ gene segments allows a single Vδ segment to frequently contact and rearrange to Dδ and Jδ segments and dominate the adult TCRδ repertoire. Disruption of this loop also narrows the TCRα repertoire, which, we believe, follows as a consequence of the restricted TCRδ repertoire. Hence, a single CTCF-mediated chromatin loop directly regulates TCRδ diversity and indirectly regulates TCRα diversity. Examination of chromatin loops by 4C-seq from 4 viewpoints in two lymphoid cell compartments: CD4-CD8- thymocytes and naïve B splenocytes.
