The mRNA methyltransferase Mettl3 modulates cytokine mRNA stability and limits functional responses in mast cells [m6A-CLIP-Seq]

Project description:Mast cells are central players in allergy and asthma, and their dysregulated responses lead to reduced quality of life and life-threatening conditions such as anaphylaxis. The RNA modification N6-methyladenosine (m6A) has a prominent impact on immune cell functions, but its role in mast cells remains unexplored. Here, by optimizing tools to genetically manipulate primary mast cells, we revealed that the m6A mRNA methyltransferase complex modulates mast cell proliferation and survival. Depletion of the catalytic component Mettl3 exacerbated effector functions in response to IgE and antigen complexes, both in vitro and in vivo. Mechanistically, deletion of Mettl3 or Mettl14 led to the enhanced expression of inflammatory cytokines. By focusing on one of the most affected mRNAs, namely the one encoding the cytokine IL-13, we found that it was methylated in activated mast cells, and that Mettl3 affected its transcript stability in an enzymatic activity-dependent manner, requiring consensus m6A sites in the Il13 3’-untranslated region. Overall, we revealed that the m6A machinery is essential in mast cells to sustain growth and to restrain inflammatory responses.

Primarily Dissecting the Autonomous and Cooperative Functions of METTL3 and METTL14 in mRNA Modification and Tumor Progression

Project description:METTL3 and METTL14 are considered to faithfully form the m6A writing complex in a 1:1 ratio, regulating the fate of mRNA by adding m6A modifications. However, recent studies have shown inconsistent expression and prognostic value of METTL3 and METTL14 in some tumors, suggesting that they may not be faithful in tumors. Pan-cancer analysis based on TCGA data reveals significant differences in expression, function, tumor burden correlation, and immune correlation between METTL3 and METTL14, especially in esophageal squamous cell carcinoma (ESCC). Knockdown of METTL3 significantly inhibits the cell proliferation in vitro and in vivo in ESCC EC109 cells, while the impact of METTL14 knockdown on proliferation is limited, and it cannot abolish the expression of METTL3 protein. mRNA-seq results indicate that METTL3 independently regulates the expression of 1615 genes, while only 776 genes are co-regulated by METTL3 and METTL14. Furthermore, through immunofluorescence co-localization, it is observed that METTL3 and METTL14 have certain inconsistencies in cellular localization. HPLC-MS results show that METTL3 independently binds to the Nop56p-associated pre-rRNA complex and mRNA splicing complex, separate from METTL14. Through bioinformatics and various omics studies, we have preliminarily discovered that METTL3 independently regulating tumor cell proliferation, and the participation in mRNA splicing may be a critical molecular mechanism. Our study provides an experimental basis and theoretical foundation for further understanding of the m6A writing complex and tumor therapy targeting METTL3.

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
