PHB1 and posterior cortical atrophy: While the analysis of the TCGA PCa cohort (n = 498) showed no significant difference in the PHB1 levels between groups with Gleason score < 7 and that with Gleason score ≥ 7, the PHB1 level was correlated with pathological T staging and clinical T staging (Pathological T staging: T2 vs. T3, P < 0.01; Clinical T staging: T1 vs. T3, P < 0.01, T1 vs. T4, P < 0.05).
