The expression of KRT8, KRT15, and KRT19 was relatively higher in AA compared to EA PCa patients in both the TCGA (Supplementary Figures 1A, C) and MSKCC cohorts (Figure 2A); the difference in expression of KRT15 was statistically significant (p ≤ 0.05) in the MSKCC (Figure 2A). This evidence concerns the gene KRT8 and posterior cortical atrophy.
