Abstract

The α-subunit comprises one-half of all glycoprotein hormones. Expression of the α-subunit gene occurs in a variety of cell types (gonadotrophs, thyrotrophs, and syncytiotrophoblasts) and is regulated by a multitude of hormones, including gonadotropin releasing hormone (GnRH), thyrotropin releasing hormone (TRH), estradiol, thyroxine, and others. Thus, this gene serves as a useful model to study various mechanisms underlying hormonal regulation and cell-specific expression. In this report we focus on the approaches we have used to characterize the cis-acting elements required for placenta- and pituitary-specific expression and hormonal responsiveness of the α-subunit gene.
