MAP1LC3B and posterior cortical atrophy: In 80 patients with PCa, MAP1LC3B protein level was positively correlated with GS (P = 0.031, immunoreactive score, immunoreactivity score (IRS) of GS < 8 was 5.36 ± 1.75, and IRS of GS ≥ 8 was 6.48 ± 2.34), but not with the pathological stage, and metastasis (Fig. 1F and Table 1).
