16. Mutations in GNRHR do not appear to be involved in the pathogenesis of constitutional delay of growth and puberty.

17. GnRH, through heterotopic expression of its receptor, may be a potential regulator of CYP11B2 expression levels in some cases of aldosterone-producing adenoma.

Rabbit Gonadotropin-Releasing Hormone Receptor (GNRHR) interaction partners

Mouse (Murine) Gonadotropin-Releasing Hormone Receptor (GNRHR) interaction partners

1. GnRH receptorexpression levels depend on JUN and are critical for reproductive function.

2. leptin's direct stimulatory actions on gonadotrope GnRHR correlate with a direct inhibition of expression of the posttranscriptional regulator MSI1. There also is a direct MSI1 interaction with 3'-UTR of Gnrhr mRNA.

3. the age-dependent basal and regulated Gnrhr transcription could account for the initial blockade and subsequent activation of the reproductive system during development.

4. GnRH-GnRHR system is not essential for growth or motor/sensory/orientation behavior during the first month of life prior to puberty onset. The lack of the GnRH-GnRHR axis, however, did affect females resulting in reduced subcutaneous inguinal fat pad weight and increased glucose with possible insulin resistance.

5. His305 of the GnRH receptor forms two distinct interactions that determine binding to GnRH and couple agonist binding to the conserved transmembrane domain network that activates GPCRs.

6. The aims of this study were to explore whether mRNA-levels of gonadotropin-releasing hormone (Gnrh) and its receptor (Gnrhr) were changed in plaque-bearing Alzheimer's disease transgenic mice.

7. Data confirm that Gnrhr mRNA and protein are expressed in ovaries, granulosa cells, cumulus cells, and oocytes.

8. Msx1 functions as a negative regulator early in pituitary development by repressing the gonadotrope-specific alphaGSU and GnRHR genes.

9. These results suggest decreased GnRH receptor signaling in the mutant animal, compared with wild type.

10. Report down-regulation of ErbB4 expression in hypothalamic neurons induced by G-protein-coupled gonadotropin releasing hormone receptor stimulation.

15. role of regulatory elements and their cognate transcription factors in transactivation of the mGnRHR gene

16. an intact AP-1 element is necessary for GnRH responsiveness of the GnRHR gene; results suggest a critical role for JNK in mediating GnRH regulation of the GnRHR gene

17. the GnRH receptor activating sequence is a composite regulatory element whose functional activity is dependent on the organization of a multi-protein complex consisting of Smads, AP-1 and a member of the forkhead family of DNA binding proteins

19. Results suggest that pituitary homeobox 1 (Pitx-1) can direct transactivation of the mouse gonadotropin-releasing hormone receptor gene, in part by DNA binding and in part by an action of Pitx-1 as a cofactor for AP-1 [Pitx-1].
