Cu-GnRH – new gonadoliberin (GnRH) analog

Postępy Higieny i Medycyny Doświadczalnej, 2013
Our research was concentrated about physiological and structural aspects of metal complexes with GnRH, which were synthetized by Professor Henryk Kozłowski from the Uniwersity of Wrocław. We found that copper, nickel, zinc and cobalt complexes with GnRH stimulated the release of LH and FSH both in vivo and in vitro.

Analysis and Characterization of Kisspeptin and Its Analogues in Serum and Urine Samples by Liquid Chromatography–High‐Resolution Mass Spectrometry for Doping Control Purposes

Drug Testing and Analysis, EarlyView.
Sensitive LC‐HRMS methods were established for the detection of kisspeptin and its analogues in serum and urine, alongside their analytical and metabolic characterization. Stability studies were conducted in serum, plasma, and urine, highlighting the importance of appropriate sample handling for reliable anti‐doping analysis.

Physiological Effects of Gonadotropin-Releasing Hormone Immunocontraception on White-Tailed Deer

Human-Wildlife Interactions, 2017
Before immunocontraceptives can be considered safe to use on wildlife species, potential health risks should be assessed. Gonadotropin-releasing hormone (GnRH) immunocontraceptive has successfully reduced fertility of white-tailed deer (Odocoileus ...

Polymorphism of the Gonadotropin-Releasing Hormone Receptor Gene and Its Association With Production Traits in Isfahani Native Hens. [PDF]

Vet Med Sci
This research was conducted to identify genetic polymorphisms of the GNRHR gene on Isfahan native hen traits and their relationship with production traits. For this purpose, blood was taken, DNA was extracted, the target fragment was amplified and directly sequenced, and finally it was blasted with the reference gene in NCBI.

Role of SoxE transcription factors in development and disease

Developmental Dynamics, EarlyView.
Abstract Sox8, Sox9, and Sox10 arose by multiple rounds of genome duplications from a single SoxE gene in ancestral vertebrates. In this review, we will briefly discuss the molecular structure and function of SoxE transcription factors and their evolutionary origin. We will then discuss their expression, function, and developmental disorders.

Development of a GnRH Radioimmunoassay Utilizing a Superactive Synthetic GnRH Analog: D-[Lys6]-GnRH

Experimental Biology and Medicine, 1978
SummarySpecific, high titer anti-GnRH antisera were obtained following immunization of rabbits with a conjugate of thyroglobulin and D-[Lys6]-GnRH. D-[Lys6]-GnRH was chosen to take advantage of an ∊-amino group in the center of the peptide chain and three carbons away from the chain as a unique point of conjugation. The RIA developed with this antisera

Goofy/123Cre lineage tracing differentiates olfactory and vomeronasal neurons from GnRH‐1 and terminal nerve neurons during neuronal migration and reveals additional olfactory placode‐derived cells in the brain

Developmental Dynamics, EarlyView.
Abstract The olfactory placode (OP) generates a broad array of chemosensory neurons in the nasal region, including olfactory sensory neurons, vomeronasal sensory neurons, neurons of the septal organ, and Grueneberg ganglion. During invagination, the OP also generates migratory neuronal populations, including gonadotropin‐releasing hormone‐1 (GnRH‐1 ...

Age, embryo donor status, and insemination with chilled semen all predispose to persistent breeding‐induced endometritis in warmblood mares

Equine Veterinary Journal, EarlyView.
Abstract Background Persistent breeding‐induced endometritis (PBIE) is a common reason for mares failing to establish pregnancy. Objective To examine the hypothesis that advancing mare age and embryo donor status predispose to PBIE and compromise fertility.
