title: The nuclear uptake of androgen by human benign prostate in vitro: action of antiandrogens.
abstract: An in vitro test system suitable to assess the potency of putative antiandrogens has been developed, using the human benign prostatic tissue obtained at operation. The system circumvents some problems associated with using human tissue, such as the presence of endogenous steroid and contamination with plasma proteins (particularly sex hormone binding globulin). Slices of tissue were incubated in the presence of 3H-testosterone and the uptake into nuclei was determined. The nature of the nuclear radioactivity and the steroid specificity indicates a mechanism similar to the established in the rat ventral prostate. The action of antiandrogens (cyproterone acetate, diethylstilbestrol, flutamide, hydroxylated flutamide and gestonorone capronate) has been studied at various concentrations.
