NANS and posterior cortical atrophy: We found that the expression levels of 82 genes (including KLK2 and HNRNPC) significantly differed between PCa and normal prostate tissues (Figure S3A; Table S1), and those of 45 and 46 genes (including KLK2, NANS, and CRIP2) significantly differed when classifying patients according to GS grade (GS > 7 compared with GS < 7) and pathological T (pT) stage (pT3 compared with pT2) (Figures S3B and S3C; Tables S2 and S3) (p < 0.05).
