In the rat ventral prostate, various antiandrogens can interfere with the normal formation of an androgen-receptor complex which appears to be required for androgen action. Some of the antagonists may act by inhibiting the enzymatic formation of 5 alpha-dihydrotestosterone or by competing with androgens for the binding sites on the receptors, whereby interacting with and altering the receptor molecules themselves. If the action of an androgen-receptor complex can indeed occur at the stage of gene transcription as well as in certain post-transcriptional processes, the molecular site of antiandrogen action may be in the nuclei and/or cytoplasm of the target cells. |
