Representative immunohistochemical stainings for AR of prostate carcinoma samples with Gleason scores = 7b in A: no diabetes; B: diabetes. C: AR diversity in immunohistochemical stainings, given in cumulated percentage of samples (%) in patients with and without diabetes, as well as in tumor-adjacent benign tissue and prostate cancer samples. The proportion of cells was scored 0–5 (green: <1%, blue: 1–10%, yellow: 11–33%, orange: 34–66%, red: 67–100%), no sample was scored 0.
