CCL21 and posterior cortical atrophy: Polymerase chain reaction analysis of PPAT and subcutaneous adipose control tissues (SAT) collected from patients with PCa undergoing radical prostatectomy or BPH control patients undergoing simple prostatectomy showed that many inflammatory genes (e.g., IL8RA, ILRAB, CXCL2, CCL8, and CCL21) in PPAT compared with SAT were associated with high grade (Gleason-9) PCa.
