RCN1 and posterior cortical atrophy: Also RCN1 expression in normal versus PCa tissues revealed statistically significant differences across several Gleason scores, including normal prostate tissue versus GS 6 (p = 7.56 × 10−4) and GS 7 (p = 1.35 × 10−4), GS 6 versus GS 9 (p = 1.17 × 10−2) and GS 7 versus GS 9 (p = 1.97 × 10−3) (Figure 6H).
