METTL14 and posterior cortical atrophy: Seven of 21 m6A regulators (HNRNPA2B1, FMR1, METTL14, KIAA1429, YTHDF1, ALKBH5, HNRNPC) displayed different expression patterns between 62 metastatic and 37 non-metastatic PCas (Figure 3B), suggesting that these seven m6A regulators were associated with PCa metastasis.
