METTL3-dependent m6A modification programs human neural progenitor cell proliferation [MeRIP-seq]

Project description:To investigate whether the role of METTL3 in hNPCs is dependent on its m6A activity,samples form neural progenitor cell (NPC) differentiation in the small molecule-assisted shut-off (SMASh) tagged hESC groups were collected. Gene expression levels were quantitated by RNA-seq analysis, and the potential target genes were identified by MeRIP-seq analysis and RIP-seq.

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

Project description: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

METTL3 Facilitates Hypertrophic Scar Fibrosis by Promoting pri-miRNA-31 Maturation and ZBTB20 Silencing in m6A-dependent Manner [MeRIP-Seq]

Project description:To clarify the role of METTL3-mediated m6A modification in hypertrophic scars (HS), we conditionally knocked out the m6A methyltransferase METTL3 in HS-derived dermal fibroblasts (HSFBs). We then performed MeRIP-seq analysis on HSFBs.

METTL3-mediated m6A modification is required for cerebellar development m6A modification and cerebellar development

Project description:N6-methyladenosine (m6A) RNA methylation is the most abundant modification on mRNAs and plays important roles in various biological processes. The formation of m6A is catalyzed by a methyltransferase complex including methyltransferase like 3 (METTL3) as a key factor. However, the in vivo functions of METTL3 and m6A modification in mammalian development remain unclear. Here we show that specific inactivation of Mettl3 in mouse nervous system causes severe developmental defects in the brain. Mettl3 conditional knockout mice manifest cerebellar hypoplasia caused by drastically enhanced apoptosis of new born cerebellar granule cells (CGCs) in the external granular layer (EGL). METTL3 depletion induced loss of m6A modification causes extended RNA half-lives and aberrant splicing events, consequently leading to dysregulation of transcriptome-wide gene expression and premature CGC death. Our findings reveal a critical role of METTL3-mediated m6A in regulating the development of mammalian cerebellum.

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.

RNA m6A modification mediated by METTL3 is important for IAP heterochromatin integrity in mESCs (MeRIP-Seq)

Project description:N6-methyladenosine (m6A) methyltransferase METTL3 mainly mediates mRNA m6A methylation and plays important roles in various biological processes. Here we report a chromatin-based role for METTL3 in heterochromatin integrity regulation in mouse embryonic stem cells (mESCs). We show that in mESCs METTL3 predominantly localizes to one of the most active endogenous retroviruses (ERVs) families, the intracisternal A-type particles (IAPs). We further show that METTL3 knockout (KO) impairs deposition of multiple heterochromatin marks on METTL3-targeted IAPs, and upregulates IAP transcription without affecting the stability of the resulting RNAs. De-repression can be rescued by wildtype but not catalytically inactive METTL3, suggesting that METTL3-mediated methylation is important for heterochromatin silencing. Mechanistically, we demonstrate that METTL3 physically interacts with the H3K9 tri-methyltransferase SETDB1 and its regulator TRIM28, and reciprocally promote each other’s localization to IAPs. Importantly, we show that m6A catalytical activity of METTL3 is necessary for its own recruitment to chromatin but not its interactions with SETDB1 and TRIM28. Taken together, our findings demonstrate that RNA m6A modification mediated by METTL3 is important for IAP heterochromatin integrity in mESCs.
