Second gene for gonadotropin-releasing hormone in humans.
Gonadotropin-releasing hormone (GnRH) is a decapeptide widely known for its role in regulating reproduction by serving as a signal from the hypothalamus to pituitary gonadotropes. In addition to hypothalamic GnRH (GnRH-I), a second GnRH form (pGln-His-Trp-Ser-His-Gly-Trp-Tyr-Pro-Gly; GnRH-II) with unknown function has been localized to the midbrain of many vertebrates. We show here that a gene ...
متن کاملA second gene for gonadotropin-releasing hormone: cDNA and expression pattern in the brain.
In vertebrates, the gonadotropin-releasing hormone (GnRH) decapeptide is secreted from hypothalamic nerve terminals to regulate reproduction via control of synthesis and release of pituitary gonadotropins. Only one GnRH peptide has been found in mammals, with one exception, although numerous other vertebrate species express more than one of the eight known decapeptide forms as shown by immunocy...
متن کاملGonadotropin-releasing hormone receptor-targeted gene therapy of gynecologic cancers.
The majority of ovarian, endometrial, and breast cancers express gonadotropin-releasing hormone (GnRH) receptors. Apart from reproductive organs (ovaries, fallopian tubes, and uterus) that are normally removed during surgical therapy of ovarian or endometrial cancer, pituitary gonadotrophs also express GnRH receptors. The signal transduction pathway in tumor cells is basically different from th...
متن کاملMolecular structure of the human gonadotropin-releasing hormone receptor gene.
GnRH receptors belong to the family of G protein-coupled receptor proteins and have been localized to the anterior pituitary, brain and reproductive organs as well as many steroid-dependent tumor tissues. Recently, cDNAs for the GnRH receptors of several species including the human have been cloned. To determine the structure of the gene encoding the human GnRH receptor, we isolated the recepto...
متن کاملGonadotropin-releasing hormone receptor-coupled gene network organization.
An early gene cDNA microarray was developed to study genes that are regulated immediately following gonadotropin-releasing hormone (GnRH) receptor activation. 956 selected candidate genes were printed in triplicate, a t statistic-based regulation algorithm was used for data analysis, and the response to GnRH in a time course from 1 to 6 h was determined. Measurements were highly reproducible wi...
