Gene expression changes in rat prostate after activation or blocking of the androgen and estrogen receptor

These data indicate that estrogens have various effects in castrated male rats and that expression of several genes is under multi-hormonal control in the ventral prostate. However, interactions between estrogens and androgens do not play a major role in the Hershberger assay, as simultaneous TP administration abolished the effects of EB. First choice of gene expression profiles in the Hershberger assay to study androgenic or anti-androgenic effects would be the traditional, TRPM-2 and PBP C3, supplemented with the new complement C3.
