An androgen response element in a far upstream enhancer region is essential for high, androgen-regulated activity of the prostate-specific antigen promoter.

Abstract excerpt

Prostate-specific antigen (PSA) is expressed at a high level in the luminal epithelial cells of the prostate and is absent or expressed at very low levels in other tissues. PSA expression can be regulated by androgens. Previously, two functional androgen-response elements were identified in the proximal promoter of the PSA gene. To detect additional, more distal control elements, DNasel-hypersensitive sites...
