METTL14 and posterior cortical atrophy: Here, we found that m6A modifications are increased in PCa and methyltransferase-like 3 (METTL3), but not other major m6A modification genes including METTL14, fat mass and obesity-associated protein (FTO) and AlkB homolog 5 (ALKBH5), was the major dysregulated gene associated with abnormal m6A modification.
