RACGAP1 and posterior cortical atrophy: In this study, we found that CDKN2C and RACGAP1 were overexpressed in PCa tissues compared to adjacent tissues, and PCa patients with Gleason score >7 and pathological stage III exhibited higher expression of CDKN2C and RACGAP1 than patients with Gleason score ≤7 and pathological stage II.
