ITIH2 and posterior cortical atrophy: Further analysis of ITIH2 expression in normal versus PCa tissues revealed statistically significant differences across several Gleason scores, including normal prostate tissue versus GS 7 (p = 7.01 × 10−3), GS 8 (p = 1.23 × 10−2), GS 9 (p = 1.41 × 10−3), GS 6 versus GS 9 (p = 1.52 × 10−2) and GS 9 versus GS 10 (p = 2.45 × 10−2) (Figure 6D).
