Abstract:

In this study, the structure and function of gonadotropin-releasing hormone (GnRH) in different vertebrate species, in the classes Aves, Reptilia and Pisces was investigated. Acetic acid extracts were subjected to gel filtration chromatography and semipreparative high performance liquid chromatography (HPLC) to partially purify the GnRHs. The GnRH immunoreactivity was then characterized by analytical HPLC, and by assaying HPLC fractions by radioimmunoassay with region-specific antisera generated against mammalian GnRH, Gln⁸-GnRH and Trp⁷,Leu⁸-GnRH and assessing luteinizing hormone (LH)-releasi

Abstract:

Hypothalamic gonadotropin-releasing hormone (GnRH) is a decapeptide that plays a pivotal role in mammalian reproduction. It is hypothesized that progesterone (P4) may regulate GnRH I, GnRH II (a second form of GnRH) and GnRH I receptor (GnRH I R) at the transcriptional level. Alternatively, GnRHs may stimulate transactivation of the progesterone receptor (PR), thereby, modulating gonadotropin subunit gene expression. Treatment of human neuronal cells with P4 suppressed GnRH I R promoter activity. This P4-stimulated inhibition was enhanced when PR A was over-expressed. With respect to the

Binding of its ligand, GnRH, results in synthesis and release of gonadotropin hormones luteinizing hormone (LH) and follicle stimulating hormone (FSH). Steroidogenic factor 1 (SF-1), a transcription factor, binds to specific sites in the promoter region of gonadotropin genes, and thus regulates transcription of these genes. The promoter region of the GnRHreceptor gene contains two SF-1-like binding sites, one at -14 to -8 (site 1) and anoth

This thesis has therefore investigated the binding characteristics of the human GnRH receptor, in comparison to those of the rat receptor, as well as the activities of a number of GnRH analogues for stimulating luteinising hormone (LH) and follicle stimulating hormo

The control of prolactin secretion is a complex interaction of peptides and neurotransmitters acting either in an inhibitory or stimulating way to effect final secretion of this hormone from the lactotrope cell in the anterior hypothalamus.

<p>Gonadotropin Releasing Hormone (GnRH) is a hypothalmic decapeptide, which regulates mammalian gonadotropin secretions by binding to specific, high affinity receptors in the pituitary.

Endocrine regulation of expression of GnRH receptors is an important step in the control of reproduction.

In long-term ovariectomized ewes, neither removal of progesterone, nor the presence of estradiol affected the expression of GnRH receptors.

Both GnRH-I and GnRH-II activate an estrogen response element (ERE)-driven luciferase reporter gene in LβT2 mouse pituitary cells, and GnRH-I is more potent in this regard.

The gonadotropin-releasing hormone (GnRH) neurons are the final output neurons of a complex neuronal network that controls fertility in all mammals.

Pituitary sensitivity to GnRH can be directly correlated with GnRHR levels on the surface of the pituitary gonadotrope cells, which can be regulated at transcriptional, post-transcriptional and post-translational levels. This study investigated mechanisms of transcriptional regulation of mouse GnRHR expression in two mouse gonadotrope cell lines, αT3-1 and LβT2, using a combination of e

Orientador: Laura Satiko Okada Nakaghi<br>Coorientador: Rafael Henrique Nóbrega<br>Banca: Elisabeth Criscuolo Urbinati<br>Banca: Matias Pandolfi<br>Resumo: O hormônio liberador de gonadotropina (GnRH) é um dos fatores chaves na regulação neuroendócrina da reprodução dos vertebrados. Alguns peixes apresentam três variantes do GnRH: o GnRH1 envolvido na secreção de gonadotropinas, o GnRH2 que regula o comportamento alimentar e sexual e o GnRH3 expresso no bulbo olfatório e o nervo terminal cujas fibras nervosas inervam a retina e o epitélio olfatório. O zebrafish possui duas variantes do GnRH (G
