YTHDF2 and posterior cortical atrophy: Upregulation of YTHDF2 was observed in TCGA PCa tissues (n = 498) compared with the normal controls (n = 52) (P < 0.001) and in Grasso Prostate cohort (Oncomine database) (Fig. 1a, supplementary figure 1A), and the expression of YTHDF2 tended to increase with the growing Gleason scores (Fig. 1b).
