While the autoregulation of AR appears to be negative in most AR‐expressing rat tissues and human cell lines,29, 30, 34 some human cells appear to have a positive AR autoregulation, including PC‐3 and DU 145 PCa cells ectopically expressing AR and osteoblastic cells of Saos‐2.35, 36, 37, 38. This evidence concerns the gene AR and posterior cortical atrophy.
