Project description:To determine the role of Mbd3/NuRD in lymphopoiesis, gene expression in purified populations of Mbd3-deleted and control lymphoid progenitor cells was analysed using RNA-seq.
Project description:To determine the role of Mbd3/NuRD in lymphopoiesis, chromatin accessbility was analysed in purified populations of Mbd3-deleted and control lymphoid progenitor cells using the assay for transposase-accessible chromatin using sequencing (ATAC-seq).
Project description:Nine different cell types (common dendritic progenitor (CDP), pre-conventional dendritic cell (pre-cDC), common dendritic progenitor (CDPr, according to Rodrigues et al., but this population was flawed in sorting purity), Flt3+ CD11c+ Siglec-H+ CCR9-low B220-low progenitor cell (lo-lo), Flt3 + CD11c+ Siglec-H+ CCR9-low B220-high progenitor cell (lo-hi), plasmacytoid dendritic cell (pDC), Ly6D+ lymphoid progenitor (SP), Ly6D+ Siglec-H+ lymphoid progenitor (DP) and common lymphoid progenitor (CLP)) were sorted to allow for analysis of their transcriptomic relation and/or similarity. The pDC_precursor_scvelo.h5ad file is a processed file ready for direct downstream analysis with scvelo.
Project description:We identified a new type of bone marrow progenitors termed early innate lymphoid cell progenitor (EILP) using TCF-1 GFP reporter mice. We compared the transcriptomes of early innate lymphoid cell progenitors (EILP) with other early progenitors, including HSC, LMPP, CMP, CLP, ETP and DN3.
Project description:Maintenance of chromatin structure is essential to eukaryotic life; dysregulation is known to be causal for aberrant development and disease. The Mi-2/nucleosome remodeling and histone deacetylase (NuRD) complex is a multiprotein machine proposed to regulate chromatin structure by nucleosome remodeling and histone deacetylation activities. We identified the localization of MBD3, a component of Mi-2/NuRD complex, in two breast cancer cell lines (MCF7 and MDA-MB-231) using ChIP-Seq. MBD3 showed cell-type specific localization with overlap across cell lines being less than 50%. MBD3 localized across gene bodies, peaking around the transcription start site (TSS). Contrary to existing models, MBD3 preferentially associated with CpG rich promoters marked by H3K4me3. These data suggest that MBD3, and by extension the Mi-2/NuRD complex, may have roles in fine tuning expression for active genes. These data represent an important first step in defining regulatory mechanisms by which Mi-2/NuRD complex controls chromatin structure and gene expression.
