KLK3 and posterior cortical atrophy: Regarding low/high PSA levels, we observed a statistically significant higher expression of miR-375-3p, miR-182-5p, and miR-21-5p (p = 0.0147, 0.0040, and 0.0082, respectively) in seminal plasma of PCa patients with PSA levels >10 μg/L, as compared to the PCa patients with PSA levels ≤10 μg/L (Figure 4).
