Abstract

Objectives. To compare the in vitro functional activity of the prostate-specific antigen (PSA) androgen response element (ARE) I alleles alone or in combination with androgen receptor (AR) polymorphisms and to determine the association of ARE I alleles with serum PSA in men without clinical prostatic disease. Data are conflicting regarding the association of PSA promoter alleles with serum PSA in men. Methods. In vitro functional analyses of ARE I and AR polymorphisms were conducted by luciferase reporter assays in LNCaP and PC-3 cells. Associations among serum PSA, ARE I, and AR genotypes were determined by genotyping 109 white and 71 African-American men determined to be free of clinical prostatic disease. Results. We found no significant difference in the androgen responsiveness of the two alleles when cells were transfected with PSA promoter reporter constructs differing only in the ARE I single nucleotide polymorphism and treated with varying doses of androgen. The response to androgens of the ARE I alleles co-transfected with AR expression vectors of 9, 21, and 29 CAG repeat lengths were identical. No individual or combined effects of the ARE I genotype and the AR genotype on serum PSA were noted. Conclusions. Our data indicate that ARE I polymorphisms, alone or in combination with AR polymorphisms, have no functional effect on the activity of the PSA promoter in vitro and in vivo.
