METTL3 promotes translation in human cancer cells

Project description:we find METTL3 associates with polyribosomes and promotes translation. METTL3 depletion inhibits translation, and both wild-type and catalytically inactive METTL3 promote translation when tethered to the 3' untranslated region (UTR) of a reporter mRNA. Mechanistically, METTL3 enhances mRNA translation through an interaction with the translation initiation machinery. m6A seq in A549 and H1299 cells, RNA seq in METTL3 knockdown cells

Identification of N6-methyladenosine (m6A) modified RNA in ILC2 of WT and Mettl3 Klrg1Cre mice

Project description:Innate lymphoid cells (ILCs) are able to directly respond to alarmin signals and produce an array of effector molecules for immune protection and tissue homeostasis. However, how posttranscriptional machinery in ILCs execute extracellular stimuli towards robust gene expression is yet to understand. Here, we reported a cell type-specific role of N6-methyladenosine (m6A) RNA methylation in ILCs. Inducible deletion of m6A methyltransferase METTL3 had little impact on ILC maintenance in the steady state or cytokine-induced ILC1 or ILC3 activation, but dramatically diminished IL-25-triggered ILC2 response. Specific deletion of Mettl3 in ILC2 significantly attenuated cell expansion, cytokine production, inter-organ migration, and anti-helminth immunity. To investigate the molecular mechanism by which m6A modification regulates ILC2 response, we subjected ILC2 of WT and Mettl3 Klrg1Cre mice to a m6A-tagged mRNA immunoprecipitation sequencing (meRIP-seq) to identify the m6A modified mRNA.

Exploring the Impact of m6A Methyltransferase Mettl3 on MASLD through Multi-Omics Analysis

Project description:Background: N6-methyladenosine (m6A) RNA modification plays a crucial role in various biological events and is implicated in various metabolic-related diseases. However, its role in MASLD remains unclear. This study aims to investigate the impact of Mettl3 on MASLD through multi-omics analysis, with a focus on exploring its potential mechanisms of action. Methods: MASLD mouse models were established by feeding a high-fat diet for 12 weeks, and Mettl3 stable overexpression AML12 cell models were constructed via lentiviral transfection. Subsequent transcriptomic and proteomic analyses, as well as integrated analysis between different omics datasets, were conducted. Results: Mettl3 expression significantly increased in MASLD mouse models. In the transcriptomic and proteomic analyses, we identified 848 genes with significant inconsistencies between transcriptomic and proteomic datasets. GO/KEGG enrichment terms may involve post-transcriptional modifications, particularly Mettl3-mediated m6A modification. Subsequently, through integrated proteomic analysis of Mettl3-overexpressed AML12 cell models and MASLD mouse models, we selected the top 20 co-upregulated and co-downregulated GO/KEGG terms as the main biological processes influenced by Mettl3 in MASLD. By intersecting with pathways obtained from previous integrated analyses, we identified GO/KEGG terms affected by Mettl3-induced m6A modification. Protein-protein interaction analysis of proteins involved in these pathways highlighted GAPDH, ENO1, and TPI1 as three key hub genes. Conclusion: In MASLD, Mettl3 regulates the glycolytic pathway through m6A modification, influencing the occurrence and development of the disease via the key hub genes GAPDH, ENO1, and TPI1. These findings expand our understanding of MASLD and provide strong evidence for potential therapeutic targets and drug development.
