摘要：
We have studied the effect of androgenic deprivation on the level of androgen receptor transcript in the rat ventral prostate. The rats were treated with estradiol benzoate, flutamide and [D Trp(6), des Gly(10)]gonadotropin releasing hormone (GnRH) for different time periods. These treatments produced a significant decrease in the weight of prostate. Total RNA isolated from the ventral prostates was hybridized with the cDNA probe for androgen receptor. Densitometric analysis of the autoradiographic signal revealed a rise in the level of androgen receptor RNA following treatment of rats with estradiol benzoate and flutamide. Treatment of rats with [D Trp(6), des Gly(10)] GnRH brought about a transient rise in the level of androgen receptor RNA. Thus, our results indicate that androgenic deprivation up-regulates the level of androgen receptor transcript.
