5α-dihydrotestosterone-induced uteroglobin synthesis in rabbit uterus is not inhibited by antiandrogen administration but is prevented by estradiol
The physiological androgen, 5α-dihydrotestosterone (DHT), enhances a progesterone-regulated protein (uteroglobin) synthesis in the rabbit uterus. In order to clarify the induction mechanism(s), rabbits were treated for 5 days with DHT alone or concomitantly with a nonsteroidal antiandrogen, RU 23908, or with different doses of estradiol. Uteroglobin content was measured in the uterine fluid by radioimmunoassay and uteroglobin mRNA activity in uterine tissues using cell-free translation in vitro. Uteroglobin induction elicited by DHT was inhibited by a small dose of estradiol, but not by antiandrogen. These results support the idea that androgens bring about their action on uteroglobin synthesis via a mechanism involving uterine progesterone receptor.
