Influence of neonatal diethylstilbestrol treatment on androgen and estrogen receptor levels in the mouse anterior prostate, ventral prostate and seminal vesicle.
Perinatal exposure to the synthetic estrogen, diethylstilbestrol (DES), affects the structure of both male and female reproductive systems. Changes may also occur in the levels of steroid hormone receptors. Cytosolic and nuclear androgen and estrogen receptor levels (expressed per mg DNA) from the sex accessory glands of male BALB/c mice exposed neonatally to DES were analyzed by exchange assays. Neonatal DES exposure caused significant decreases in: (1) cytosolic androgen and cytosolic and nuclear estrogen receptor levels in the anterior prostate and (2) cytosolic estrogen receptor levels in the ventral prostate. A significant increase was seen in the cytosolic estrogen receptor levels in the seminal vesicle. Significant decreases in cytosolic protein levels occurred in all DES-exposed glands.
