Journal ArticleDOI
The GPR54 gene as a regulator of puberty
Stephanie B. Seminara,Sophie Messager,Emmanouella E. Chatzidaki,Rosemary R. Thresher,James S. Acierno,Jenna K. Shagoury,Yousef Bo-Abbas,Wendy Kuohung,Kristine M. Schwinof,Alan G. Hendrick,Dirk Zahn,John Dixon,Ursula B. Kaiser,Susan A. Slaugenhaupt,James F. Gusella,Stephen O'Rahilly,Mark Carlton,William F. Crowley,Samuel Aparicio,William H. Colledge +19 more
TL;DR: Puberty is initiated when gonadotropin-releasing hormone begins to be secreted by the hypothalamus, and complementary genetic approaches in humans and mice identified genetic factors that determine the onset of puberty.
Journal ArticleDOI
Kisspeptin directly stimulates gonadotropin-releasing hormone release via G protein-coupled receptor 54
Sophie Messager,Emmanouella E. Chatzidaki,Dan Ma,Alan G. Hendrick,Dirk Zahn,John Dixon,Rosemary R. Thresher,Isabelle Malinge,Didier Lomet,Mark B. L. Carlton,William H. Colledge,Alain Caraty,Samuel Aparicio +12 more
TL;DR: GPR54 is defined as a major control point in the reproductive axis and kisspeptin is suggested to be a neurohormonal effector, demonstrating that a key action ofkisspeptin on the hypothalamo-pituitary-gonadal axis occurs directly at the level of GnRH release.

The GPR54 Gene as a Regulator of Puberty
Stephanie B. Seminara,Sophie Messager,Emmanouella E. Chatzidaki,Rosemary R. Thresher,James S. Acierno,Jenna K. Shagoury,Yousef Bo-Abbas,Wendy Kuohung,Kristine M. Schwinof,Alan G. Hendrick,Dirk Zahn,John Dixon,Ursula B. Kaiser,Susan A. Slaugenhaupt,James F. Gusella,Stephen O'Rahilly,Mark Carlton,William F. Crowley,Samuel Aparicio,William H. Colledge +19 more
TL;DR: Mutations in GPR54, a G protein-coupled receptor gene, cause autosomal recessive idiopathic hypogonadotropic hypogOnadism in humans and mice, suggesting that this receptor is essential for normal gonadotropin-releasing hormone physiology and for puberty.
Journal ArticleDOI
Kisspeptin and its receptor: new gatekeepers of puberty.
TL;DR: It is the first time since the identification of gonadotrophin‐releasing hormone that a single gene is found to have such a dramatic effect on reproduction.

TL;DR: In this article, the use of a galanin-like receptor and ligands thereof in the manipulation of the pituitary hormonal axis and reproductive systems is described. But the present invention relates to the use
