1. Gonadotropin-releasing hormone (GnRH) is the hypothalamic releasing factor that controls pituitary gonadotropin subunit gene expression and indirectly gametogenesis and steroidogenesis from the gonad, which results in reproductive competence. 2. GnRH is synthesized in only about 1000 neurons in the hypothalamus and released in an episodic fashion down the median eminence to regulate gonadotropin biosynthesis. 3. Although much is known about the secretory dynamics of GnRH release, little is known about the pretranslational control of GnRH biosynthesis due to lack of appropriate model systems. The recent availability of immortalized neuronal cell lines that produce GnRH allows investigators for the first time to begin to dissect the factors that directly regulate GnRH gene expression. 4. This article reviews the current state of knowledge concerning the mechanisms that direct tissue-specific and peptide hormone control of GnRH biosynthesis.
