Songbirds have a complex neural network for learning and production of song, namely the neural song system. Several nuclei of the song system contain androgen receptors (AR), and the neostriatal nucleus HVc also contains alpha type estrogen receptors (ER). Many songbird species show seasonal changes

Androgens and estrogens are crucial for the differentiation and function of the vocal control system of songbirds. A major source of estrogens in songbirds is the cerebral aromatization of circulating testosterone by aromatase (ARO). In the vocal control system, songbirds have a unique estrogen rece
## Background: Because of the significance of androgens and estrogens in prenatal and postanatal differentiation of the testis and excurrent ducts, it is important to understand the developmental pattern of androgen receptor (ar) and estrogen receptor (er) in these organs. ## Methods: Tissues fro
The role of insulin-like growth factor-I (IGF-I) in regulating estrogen receptor-␣ (ER-␣) gene expression and activity was investigated in the human breast cancer cell line MCF-7. Treatment of cells with 40 ng/ml IGF-I resulted in a 60% decrease in ER-␣ protein concentration by 3 h, and the amount o
