Expression of 16 m6A RNA methylation regulators is shown in Figure 5A, and 11 of them were significantly differentially expressed in the myometrium of adenomyosis patients including RBM15/15B, ALKBH5, FTO, YTHDF1/2, KIAA1429, HNRNPC, METTL3, ZC3H13, and YTHDC2 (Figure 5A). This evidence concerns the gene YTHDC2 and adenomyosis.
