Pooled CRISPR Screening Identifies m6A as a Positive Regulator of Macrophage Activation [m6A-RIP-seq]

ABSTRACT: Total RNAs were isolated from WT_CON, KO_CON, WT_LPS and KO_LPS Raw 264.7 cells, subjected to standard m6A RIP protocol. The libraries were generated with IPed and Input RNAs and subjected to Sequencing. Raw sequencing reads were aligned to the mouse genome (mm10) with Tophat , and gene expression levels were measured by Cufflinks.

Pooled CRISPR Screening Identifies m6A as a Positive Regulator of Macrophage Activation [RNA-seq]

Project description:The involvement of m6A modification in macrophage activation has been validated in our study that the expression of TNF-α in Mettl3-depleted Raw 264.7 cells stimulated with LPS were markedly reduced in comparison to control cells. To further explore the biological effects of m6A deficiency macrophages, we performed RNA sequencing analysis of Mettl3-KO and WT control Raw 264.7 cells upon LPS treatment. The GO enrichment analysis documented that the downregulated transcripts in Mettl3-KO Raw 264.7 cells were enriched in innate immune response related to defense and external stimulus. Notably, transcripts of the downstream components of the TLR4 signaling pathway, such as proinflammatory cytokines (Tnf-α, Il-6, Il-1β, Il-18,and Il-23) and co-stimulation molecules (Cd86), were downregulated in Mettl3-deficient cells, suggesting that METTL3 has a critical function in controlling the innate immune response of Raw 264.7 macrophages.

m6A-MeRIP sequencing of NK cells

Project description:Total RNAs were isolated from WT splenic NK cells, and subjected to standard m6A MeRIP, in two replicates, using Illumina Novaseq 6000 platform. The raw sequencing reads were mapped to the genome of Mus musculus (mm10) with default parameters. ExomePeak was used to identify m6A peaks, which were annotated by intersection with gene architecture using ChIPseeker. Sequence motifs enriched in peak regions were identified using Homer.

P23 acts as an RNA binding protein, which interacts differentially with specific mRNAs in response to LPS and modulates the macrophage inflammation response

Project description:We report the identification of RNAs bound by P23, which was previously uncovered as new poly(A+)-RNA interacting protein in murine RAW 264.7 macrophages (Liepelt, et al., 2016). RNAseq of RNAs immunoprecipitated with P23 revealed that specifc mRNAs were bound differentially in untreated and in LPS-activated RAW 264.7 cells.

m6A modification in effector CD4+ T cells [m6A-miCLIP-seq]

Project description:GP61-primed effector CD4+ T cells were isolated from Ctrl or Mettl3-deficient SMARTA mice. Total RNAs were extracted with TRIzol reagent, and mRNAs were then isolated with Dynabeads® mRNA purification kit, followed by stardard m6A-miCLIP-SMARTer-seq with some modifications. Raw sequencing reads were aligned to the mouse genome (mm10) with BWA, and then m6A sites were determined.

Global gene transcriptional profiles of RAW 264.7 cells following the infection with Brucella abortus wild and mutant strains

Project description:We focused on whether transposon mutagenesis in Brucella abortus could induce difference in the trascriptional responses of RAW 264.7 cell infection model compared to the wild strain infected RAW 264.7 cells. The function of genes in Brucella abortus was analyzed through the identified differences in gene expression between RAW 264.7 cell infected with wild and mutant strains.

Next Generation Sequencing of Wild Type and Hnrnpul1-/- RAW 264.7 Cells Transcriptomes

Project description:Purpose: The goal of this study is to compare NGS-derived wild type and Hnrnpul1 knockout (Hnrnpul1-/-) RAW 264.7 cells transcriptomes with or without LPS stimulation. Methods: Sequancing was performed by Novogene China Co. Ltd. RNA profiles of wild type and Hnrnpul1-/- RAW 264.7 cells as well as LPS stimulated (10 h) wild type and Hnrnpul1-/- RAW 264.7 cells were generated by deep sequencing using Illumina Novaseq 6000. Index of the reference genome was built using Hisat2 v2.0.5 and paired-end clean reads were aligned to the reference genome using Hisat2 v2.0.5. featureCounts v1.5.0-p3 was used to count the reads numbers mapped to each gene. And then FPKM of each gene was calculated based on the length of the gene and reads count mapped to this gene. Method of TMM was used to normalize the readcount. Negative binomial distribution model was used to calculate the P value, and FDR was calculated by the method of Benjaminiand Hochberg. Results: Using an optimized data analysis workflow, we mapped about 40 million sequence reads per sample to the mouse genome (GRCm38/mm10). Comparing to wild type RAW 264.7 cells, 237 genes were up-regulated and 181 genes were down-regulated in Hnrnpul1-/- cells. At 10 h following LPS stimulation, 341 genes were up-regulated and 288 genes were down-regulated in Hnrnpul1-/- cells. Genes were pre-ranked according to log2FoldChange(KO/WT) followed by GSEA and 6 gene sets were significantly enriched. Significantly differential genes were undergone GO analysis (biological process) and biological process including cell-cell adhesion, positive regulation of cell activation and regulation of response to external stimulus were enriched. Conclusions: Lacking Hnrnpul1 promotes the expression of inflammatory cytokines in LPS stimulated RAW 264.7 cells.
