The expression of the m6A RNA methylation regulator in ovarian cancer patients with and without BRCA1 mutation was also analyzed, and it has been found that the expression of both FMR1 and YTHDF1 showed differences between BRCA1-mutation and non-BRCA1-mutation groups (SupportingFigure 5). This evidence concerns the gene YTHDF1 and ovarian carcinoma.
