Cross-linking and immunoprecipitation (CLIP) analysis for identifying binding sites of Tet2 in bone marrow derived mast cell

ABSTRACT: To transcriptome-widely identify the mRNA targets of Tet2 and investigate the immunological function of Tet2 at RNA regulation level in vivo, we performed CLIP-seq of Tet2 in BMMCs. We performed three bio-replicates of CLIP-seq for getting potential Tet2-binding mRNAs.Using data of normalized tag numbers in the common peaks, we found that biological replicates correlated well with each other.More than 60% of the peaks located in genic regions, which were preferentially enriched in coding sequencing (CDS) among mature mRNA elements.

Distinct 5-methylcytosine profiles in poly(A)RNA from mouse bone marrow derived mast cells

Project description:Purpose: To transcriptome widely reveal 5-mC regulation by Tet2, we performed bisulfite-sequencing of mRNAs from Tet2-deficient BMMCs and the control cells.Methods: Mouse BMMCs were generated from bone marrow cells in RPMI-1640 medium with recombinant mouse IL-3 and SCF. BMMCs were stained to confirm the surface expression of FcɛRI and c-Kit. Cells with purity >97.5% were used for RNA isolation. Results: We carried out an unbiased global analysis of m5C in poly(A)RNA of mouse bone marrow derived mast cells (BMMCs).We show that there were indeed much more mCs in Tet2-deficient group compared with the control, more than half of which located in genic region. Furthermore, we observed that although much less mCs distributed in the three elements of exon regions, more mCs located in 3`-UTR for Tet2-deficient group compared with the control.

Next Generation Sequencing Facilitates Quantitative Analysis of Bone Marrow Derived Mast Cell Transcriptomes

Project description:Purpose:The purpose of this study is to detect activated or silenced genes during Tet2-deficient bone marrow derived mast cell (BMMC) and the control cells. Gene expression differences between two samples could be found using transcriptome profiling (RNA-seq) analysis. Methods:Mouse BMMCs were generated from bone marrow cells in RPMI-1640 medium with recombinant mouse IL-3 and SCF. BMMCs were stained to confirm the surface expression of FcɛRI and c-Kit. Cells with purity >97.5% were used for subsequent experiments. BMMCs RNA profiles were generated by deep sequencing,using Illumina. Results: We mapped about 10 million sequence reads per sample to the mouse genome, identified hundreds of genes with significant mRNA variation between Tet2-deficient BMMC and the control cells.

Mast Cell Maturation is Driven via a Novel Group III Phospholipase A2-Prostaglandin D2-DP1 Receptor Paracrine Axis

Project description:Microenvironment-based alterations in mast cell phenotypes influence the susceptibility to anaphylaxis, yet the mechanisms underlying proper maturation of mast cells toward an anaphylaxis-sensitive phenotype are incompletely understood. Here we report that PLA2G3, a mammalian homolog of anaphylactic bee venom phospholipase A2, regulates this process. PLA2G3 secreted from mast cells is coupled with fibroblastic lipocalin-type PGD2 synthase (L-PGDS) to provide PGD2, which facilitates mast cell maturation via PGD2 receptor (DP1). Mice lacking PLA2G3, L-PGDS or DP1, mast cell-deficient mice reconstituted with PLA2G3- or DP1-null mast cells, or mast cells cocultured with L-PGDS-ablated fibroblasts exhibited impaired mast cell maturation and anaphylaxis. Thus, we describe a lipid-driven PLA2G3-L-PGDS-DP1 loop that drives mast cell maturation. Mast cell maturation; immature and mature bone marrow-derived mast cells (BMMCs); Four-condition experiment (mature BMMCs vs immature BMMCs, Pla2g3M-bM-^@M-^S/M-bM-^@M-^S vs Pla2g3+/+); 3 replicates of Pla2g3+/+ BMMCs, 4 replicates of Pla2g3M-bM-^@M-^S/M-bM-^@M-^S BMMCs, 4 replicates of Pla2g3+/+ cocultured BMMCs, 3 replicates of Pla2g3M-bM-^@M-^S/M-bM-^@M-^S cocultured BMMCs

PEST-domain-enriched tyrosine phosphatase and glucocorticoids as regulators of mast cell signalling

Project description:PEST-domain-enriched tyrosine phosphatase (PEP) is a cytoplasmic protein tyrosine phosphatase that regulates immune cell functions, including mast cell functions. Using bone marrow derived mast cells (BMMCs) from PEP+/+ and PEP-/- mice, RNA-seq data showed that dinitrophenol (DNP) - activated PEP-/- BMMCs have misregulated gene expression, with some cytokine/chemokine genes (eg.TNFα, IL13, CSF2) showing reduced gene expression in the dinitrophenol (DNP) - activated PEP-/- BMMCs compared to (DNP)-activated PEP+/+ BMMCs. Also, the ability of the glucocorticoid dexamethasone (Dex) to negatively regulate DNP - induced COX-2 gene expression in PEP-/- BMMCs was inhibited compared to the PEP+/+ BMMCs.

eIF4G2 cross-linking immunoprecipitation (CLIP) in primary cortical neurons

Project description:Learning and memory require activity-induced changes in mRNA translation within dendrites, but which mRNAs are involved and how they are regulated remain unclear. We combined proximity labeling with ribosome profiling and CLIP to monitor how depolarization impacts dendritic translation. For a functionally coherent set of transcripts highly enriched in mitochondrial genes, depolarization leads to enhanced uORF translation, eIF4G2 binding, and increased translation. Engineered reporters demonstrate that activity-dependent translational control is conferred by the 5’UTRs and that dendritic localization, eIF4G2 binding, and uORF translation are necessary and sufficient to mediate this regulation. Downstream, this drives activity-dependent changes in dendritic mitochondrial function. Our studies uncover an unanticipated mechanism by which activity-dependent uORF translational control by eIF4G2 enables the coupling of synaptic activity to local remodeling of dendrites.

SCF -licensed induction of a mucosal mast cell-like transcriptional program by TGF-b

Project description:This study evaluates the effects of 72h stimulus with stem cell factor (SCF) (100 ng/mL) and TGF-b (1 ng/mL or 10 ng/mL), both alone and in combination, on the transcriptome of bone marrow-derived cultured mast cells (BMMCs) grown in IL-3 for 6-8 weeks. Through this approach, we find that SCF dramatically enhances TGF-b mediated upregulation of signature genes associated with mucosal mast cells, including transcripts encoding the proteases mMCP-1 (Mcpt1) and mMCP-2 (Mcpt2). Replicates indicate biologic duplicates. Samples were sequenced on an Illumina NextSeq 500.

Photoactivatable-Ribonucleotide-Enhanced Crosslinking and Immunoprecipitation (PAR-CLIP) of the RNA-binding protein (RBP) RBM4 in KBM-7 derived near-haploid human cell line, HAP1.

Project description:We hypothesized that RBM4 regulates HERVs by directly binding to their transcripts. To test this possibility, we performed photoactivatable ribonucleoside-enhanced crosslinking and immunoprecipitation (PAR-CLIP). We performed four independent PAR-CLIP replicates of our own using HAP1 cells stably expressing a FLAG-tagged RBM4 (FLAG-RBM4) transgene under control of a doxycycline-inducible promoter. Following metabolic labeling with 4-thiouridine (4SU) and crosslinking with ultraviolet light (UV) of 312 nm wavelength, we isolated RNA covalently linked to FLAG-RBM4. The RNA recovered from four biological replicates was converted into cDNA libraries and deep sequenced.

Landscape of Star-PAP mRNA association along with its co-regulator RBM10 using HITS-CLIP (high-throughput sequencing coupled with cross-linking immunoprecipitation).

Project description:We employed HITS-CLIP to map genome wide Star-PAP mRNA binding and define the role of RBM10 on global Star-PAP mRNA association. We show a transcriptome-wide association of Star-PAP which is diminished on cellular Star-PAP depletion. HITs-CLIP data analysis of RBM10 knockdown and pulldown with anti Star-PAP antibody on HEK293 cells indicates significance of RBM10 in Star-PAP and mRNA association.
