Project description:N6-methyladenosine (m6A) is the most abundant mRNA modification in mammalian cells, mediated co-transcriptionally by a methyltransferase ‘writer’ complex containing METTL3 as the S-adenosyl methionine (SAM)-binding subunit as well as adaptors such WTAP and ZC3H13.
Project description:We have developed a modified eCLIP-based method (meCLIP) to identify m6A residues at single-nucleotide resolution. By coupling the improvements of eCLIP with an easy-to-use computational pipeline, we have successfully identified over 50,000 unique m6A residues in the two breast cancer cell lines that were analyzed (MCF-7 and MDA-MB-231) and over 8,000 unique residues in HEK-293 cells. We compared these residues to the sites called using the currently most utilized m6A identification method (miCLIP).
Project description:Purpose: Mouse BMDM is the universal cell type of studying innate immunity.This study was to analyze LPS induced innate immune respone and the relationship between serine synthesis pathway and LPS induced innate immune respone Methods: BMDM cells were treated with or without LPS for 6 hours in the pressence of phgdh inhibitor or not. Then mRNA profiles of these samles were generated by High-throughput sequencing analysis, in triplicate, using illumina HiSeqTM 2000. And the differencial mRNA profiles were analyzed. Results: mRNA profiles about 23002 genes were analyzed, and differencial expression profiles were compared . Conclusions: Our study represents the first detailed analysis of transcriptomes of mouse BMDM treated with LPS and phgdh inhibitor, with biologic replicates, generated by RNA-seq technology. This data was useful to analyze the relationship between serine synthesis pathway and LPS induced innate immune respone
Project description:This SuperSeries is composed of the following subset Series: GSE36958: Gene expression profiles of WT and ime4-/- mutant yeast cells, under vegetative and meiosis-inducing conditions GSE37001: METTL3 KD in HepG2 cells GSE37002: m6A mapping in human RNA (with treatments) GSE37003: m6A mapping in human RNA (untreated) GSE37004: m6A mapping in mouse RNA (mouse liver and human brain) Refer to individual Series
Project description:Bone marrow cells were isolated from wild type mouse (WT) or STAT T403A mutant mouse (T403A) and primed with M-CSF (M BMDM) separately. The difference between these two M-BMDMs were distinguished by RNA-seq analysis.
Project description:We developed a novel approach, m6A-seq, for high-resolution mapping of the transcriptome-wide m6A landscape, based on antibody-mediated capture followed by massively parallel sequencing Identification of m6A modified sequences in mouse liver and human brain
