SOX10 and posterior cortical atrophy: The expression levels of SOX7 (IRS: PCa = 4.01 ± 0.160 vs. Benign = 4.79 ± 0.279, p = 0.024) and SOX10 (IRS: PCa = 2.76 ± 0.174 vs. Benign = 4.00 ± 0.424, p = 0.010) in PCa tissues were lower than those in adjacent benign prostate tissues significantly (Figure 2).
