MeRIP-Seq (m6A-Seq) identifies the mRNA m6A modification target in negative control and METTL3 knockdwon HULEC-5a

ABSTRACT: To identify the molecular mechanism by which METTL3 regulates endothelial barrier function, we performed RNA-seq and MeRIP-seq in HULEC-5a cells with stable METTL3 knockdown and control cells. The RNA-seq results revealed that 437 transcripts were significantly downregulated (fold change <0.5) after METTL3 knockdown. The MeRIP-seq results revealed that the m6A peaks in 1011 transcripts were decreased in abundance (fold change >1.2). Intriguingly, 55 transcripts overlapped in the RNA-seq and MeRIP-seq data

Transcriptome-wide maps of m6A RNA methylation marks in murine liver

Project description:N6-methyladenosine (m6A), the most prevalent modification of mRNAs at the (G/A)(m6A)C motif installed by METTL3 that plays critical role in regulation of gene expression. METTL3 is essential for embryonic development, and its dysregulation is linked to various diseases including metabolic disorders and cancer. Here, we provide insight into this by generating Mettl3fl/fl; Alb-Cre (M3LKO) mice carrying a hepatocyte-specific deletion of Mettl3. RNA-seq and MeRIP-seq analyses of mRNA identified significant dysregulation of metabolic genes in M3LKO mice.

METTL3 mediated m6A mRNA methylation regulates neutrophil activation through targeting TLR4 signaling (meRIP-Seq)

Project description:To investigate the effect of METTL3 function in the regulation of neutrophil activation, we established neutrophil METTL3 knock out mice by crossing METTL3flox/flox mice with Lyzm-cre mice. We then performed gene expression profiling analysis using data obtained from MeRIP-seq of isolated neutrophil from METTL3f/f and METTL3f/f Lyzm-Cre mice .

Determine the methyltransferase activities of METTL3, METTL14, and METTL16 via MeRIP-seq (m6A-seq)

Project description:All the three enzymes, METTL3, METTL14, and METTL16, belong to methyltransferase like (METTL) family and possess the ability to deposit N6-methyladenosine (m6A) in mRNA. Via immunofluorescence staining and wertern blotting, we discovered either METTL3 or METTL14 mainly localize in nuclear, but METTL16 localizes in both cytosol and nuclei. To compare the m6A methyltransferase activities of the three m6A 'writers' and better understand their differences, MeRIP-seq (m6A-seq) was conducted with poly(A) RNAs isolaed from HEK293T cells with METTL3, 14 and 16 knockout.

Genome-wide analysis of m6A modification

Project description:N6-methyladenosine (m6A) might exert stronger affection on circRNA expression, beyond linear genes.We confirmed the view by analysing total RNA meRIP-Seq from GSE114150 and three other sets of data using RNA sequencing. Here, we study the difference in circRNA levels between wild (WT) and experimental (D395A-mutation; METTL3-knock-out) groups when m6A level changes. Results reveal knockout and D395A mutation of METTL3 could both increase the circRNA expression and the ratio of circular-to-linear. Our data propose a new pattern of circRNAs development and expand the understanding of m6A functions.
