KLK2 and posterior cortical atrophy: Moreover, as we have shown in Supplementary Tables S1 and S2 (summarized in Table 2), we obtained some known PCa biomarkers such as α-methylacyl-CoA racemase (AMACR) [44,45], forkhead box A1 (FOXA1) [46,47,48], two members of the kallikrein related peptidase (KLK) gene family KLK2 [49,50] and KLK4 [51,52,53], prostate-cancer-associated 3 (PCA3) [54,55,56], distal-less homeobox 1 (DLX1), and a member of the homeobox (HOX) family HOXC6 [57], which play specific roles in PCa development.
