Effect of Gonadotrophin Releasing Hormone (GnRH) on the Reproductive Performance in Ossimi Ewes [PDF]
Journal of Veterinary Medical Research, 2022 This study aimed to evaluate the influence of gonadotrophin releasing hormone (GnRH) administration to Ossimi ewes before mating on their conception, lambing and prolificacy rates, and their mean lambs’ birth weights. Twenty-one (three to five years old)

Gonadotropin Releasing Hormones and their Receptors in Avian Species
The Journal of Poultry Science, 2006 In all vertebrates, gonadotropin releasing hormone (GnRH) is a key component of the hypothalamo-pituitary-gonadal axis. In birds, two distinct forms of GnRH (cGnRH-I and cGnRH-II) have been characterized, and a third immunoreactive form similar to ...

Endogenous regulation of the GnRH receptor by GnRH in the human placenta [PDF]
Molecular Human Reproduction, 2001 Gonadotrophin releasing hormone (GnRH) plays an important regulatory role in the function and growth of human placenta, but its placental expression sites and co-localization with GnRH receptor (GnRH-R) are not well known. GnRH and GnRH-R expression has been found in both placenta and cultured trophoblasts; however, cultured trophoblastic cells very ...

Advanced Science, EarlyView.A paternal glucocorticoid–sperm Gnas‐ICR axis is linked to ovarian endocrine programming in female offspring. Paternal preconception caffeine exposure elevates corticosterone, promotes sperm Gnas‐ICR hypermethylation, and is associated with ovarian Gnas upregulation, cAMP/PKA/CREB–StAR activation, enhanced estradiol synthesis, and PPP‐like phenotypes ...

Biology, 2019 The regulation of reproductive function by glucocorticoids occurs at all levels of the hypothalamo-pituitary-gonadal axis. Within the pituitary, glucocorticoids have been shown to directly alter gene expression in gonadotrophs, indicating that these cell

Hypothalamic Control of Liver Health and Disease: From Circuits to Pathophysiology and Therapies
Advanced Science, EarlyView.This review delineates the hypothalamic circuits that control liver homeostasis via autonomic and neuroendocrine pathways. Dysregulation of this hypothalamus–liver axis drives disease progression across a spectrum including steatotic liver disease, liver inflammation and injury, fibrosis, cirrhosis, and hepatocellular carcinoma.
