Kisspeptin and GPR54: discovery of a novel pathway in reproduction.
In order to find novel modulators of gonadotrophin-releasing hormone (GnRH) secretion, genetic tools were employed in patients with idiopathic hypogonadotrophic hypogonadism (IHH). Mutations in a G-protein coupled receptor, GPR54, were identified, making this receptor a genetic determinant and indisputable gatekeeper of normal reproductive function. This article places these investigations into...
متن کاملGPR54 and kisspeptin in reproduction.
Kisspeptins, the peptide products of the KiSS-1 gene, were identified in 2001 as natural ligands of the previously orphan G protein-coupled receptor, GPR54. They include, among others, metastin and kisspeptin-10. The known biological functions of kisspeptins were initially restricted to their ability to suppress tumour metastasis, hence the name of metastin. However, in late 2003, two groups in...
متن کاملEmerging ideas about kisspeptin- GPR54 signaling in the neuroendocrine regulation of reproduction.
Neurons that produce gonadotropin-releasing hormone (GnRH) drive the reproductive axis, but the molecular and cellular mechanisms by which hormonal and environmental signals regulate GnRH secretion remain poorly understood. Kisspeptins are products of the Kiss1 gene, and the interaction of kisspeptin and its receptor GPR54 plays a crucial role in governing the onset of puberty and adult reprodu...
متن کاملKisspeptin/Gpr54-independent GnRH activity in Kiss1 and Gpr54 mutant mice
The kisspeptin/Gpr54 signaling pathway plays a critical role in reproduction by stimulating the secretion of GnRH, yet mice carrying mutations in Kiss1 (which encodes kisspeptin) or Gpr54 exhibit partial sexual maturation. For instance, a proportion of female Kiss1−/− and Gpr54−/− mice exhibit vaginal oestrus, and some male Kiss1−/− and Gpr54−/− mice exhibit spermatogenesis. To characterise thi...
متن کاملwuthering heights and the concept of marality/a sociological study of the novel
to discuss my point, i have collected quite a number of articles, anthologies, and books about "wuthering heights" applying various ideas and theories to this fantastic story. hence, i have come to believe that gadamer and jauss are rightful when they claim that "the individaul human mind is the center and origin of all meaning," 3 that reading literature is a reader-oriented activity, that it ...
