Therefore, the expression levels of 7 m6A regulators (METTL14, YTHDC2, FTO, ALKBH5, HNRNPA2B1, VIRMA, and RBMX) were lower in both the OC tissues and the high-stage group, indicating their potential function as tumor suppressors in OC tumorigenesis and development. This evidence concerns the gene FTO and neoplasm.
