    Abstract:
    N6-methyladenosine (m6A) is the most prevalent modification found in eukaryotic RNA and played a significant role in various cancers. However, the mechanism by which m6A modification influences cervical cancer (CC) tumorigenesis remains unclear. Therefore, we aim to elucidate the role and mechanism of METTL3 in CC progression. In the present study, we observed a significant upregulation of METTL3 in CC tissues and cell lines. Knockdown of METTL3 resulted in reduced growth, migration, and invasion of CC cells, as well as affected apoptosis, while overexpression of METTL3 reversed these effects. Through a combined analysis of meRIP-seq and Ribo-seq data following METTL3 knockdown, NEK2 was identified as a key target of METTL3 in CC cells. Correlation analysis, MeRIP-qPCR, and luciferase reporter assay suggested that METTL3 regulates NEK2 expression through m6A modification. NEK2 synergized with METTL3 to mediate the malignant phenotype of CC cells. The METTL3-NEK2 axis promoted CC progression by activating the Wnt/β-catenin pathway and inhibiting the apoptosis pathway. In conclusion, METTL3 facilitated the malignant progression of CC and contributed to the formation of the METTL3-NEK2 regulatory axis in an m6A-dependent manner, which represented a potential target for CC therapy.
