Abstract：
:The steroid receptor-positive human ovarian cancer (BG-1) was evaluated to determine its usefulness as a tumor model. This tumor grows in intact male and female nude mice without hormone supplements. Moreover, its growth was significantly accelerated in ovariectomized mice, and the increased growth rate could be reversed by estradiol administration. Evaluation of tumor growth following endocrine therapy revealed that, while antiandrogens did not affect the tumor growth, both an aromatase inhibitor and a luteinizing hormone-releasing hormone agonist significantly impaired growth of this human ovarian tumor. Estradiol was also shown to up-regulate both estrogen and progesterone receptors in tumors grown in ovariectomized mice. Therefore, the BG-1 human ovarian carcinoma grows without hormonal supplements and yet responds to specific forms of endocrine therapy. Moreover, the steroid receptors present in this tumor respond to exogenous steroids. In conclusion, this tumor may serve as an ideal model for the study of hormonal regulation of ovarian tumor growth.
