Project description:We investigated the mechanism by which the m6A methyltransferase METTL14 functions in neuroblastoma. To explore the downstream target genes of METTL14, we performed RNA-seq analysis and found that the expression profile of the gene was significantly altered in METTL14 knockdown SK-N-BE(2) cells. We found that overexpression of METTL14 in neuroblastoma patients was a detrimental factor.

Project description:RNA methylation is involved in the regulation of cell response and cell fate, and is closely related to the development of tumors. METTL14 is considered to be a m6A methyltransferase. Studies have found that METTL14 is associated with the occurrence and development of a variety of tumors, but the mechanism in neuroblastoma is not clear. The expression of METTL14 in high risk patients was significantly higher than that in low risk patients. Interference with METTL14 expression in SK-N-BE(2) cells significantly interfered with cell cycle and inhibited cell proliferation, migration and invasion. In neuroblastoma, METTL14 activates the PI3K/AKT signaling pathway by targeting YWHAH by upregulating m6A levels in mRNA transcripts. In all findings, it was suggested that METTL14 has a cancer-promoting function in neuroblastoma.

Project description:SETD2 is the specific methyltransferase of H3K36me3, while METTL14 is a critical subunit of the m6A methyltransferase complex. To evaluate the effect of SETD2 and METTL14 on translation, we conducted robosome profiling in SETD2 and METTL14 knockdown and control HepG2 cells. Our RNA ribosome profiling revealed that depletion of SETD2 and METTL14 resulted in a global reduction in RNA translation and the changes of translation efficiency were correlated between SETD2 and METTL14 knockdown cells.

Project description:To evaluate the effect of SETD2 and METTL14 on mRNA stability, we conducted RNA-seq in SETD2 or METTL14 knockdown HepG2 cells as well as control cells with or without actinomycin D treatment. Our RNA stability profiling revealed that depletion of SETD2 and METTL14 resulted in global reduction of RNA stability, and the changes were correlated between SETD2 and METTL14 knockdown cells.

Project description:METTL14 regulates neuroblastoma through the m6A modification
| PRJNA1022448 | ENA
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.

Project description:The N6-methyladenosine (m6A) RNA modification is an important regulator of gene expression. m6A is deposited by a methyltransferase complex that includes methyltransferase-like 3 (METTL3) and methyltransferase-like 14 (METTL14). High levels of METTL3 and METTL14 drive the growth of many types of adult cancer, and METTL3/METTL14 inhibitors are emerging as new anticancer agents. However, little is known about the m6A epitranscriptome or the role of the METTL3/METTL14 complex in neuroblastoma, a common pediatric cancer. Here, we show that METTL3 knockdown or pharmacologic inhibition with the small molecule STM2457 leads to reduced neuroblastoma cell proliferation and increased differentiation. These changes in neuroblastoma phenotype were associated with decreased m6A deposition on transcripts involved in nervous system development and neuronal differentiation and increased stability and expression of target mRNAs. In preclinical studies, STM2457 treatment suppressed the growth of neuroblastoma tumors in vivo. Together, these results support the potential of METTL3/METTL14 complex inhibition as therapeutic strategy against neuroblastoma.
