Investigating the KNDy hypothesis in humans by co-administration of kisspeptin, neurokinin B and naltrexone in men [PDF]
Context: A subpopulation of hypothalamic neurons co-localise three neuropeptides namely kisspeptin, neurokinin B (NKB) and dynorphin collectively termed KNDy neurons. Animal studies suggest they interact to affect pulsatile GnRH release (KNDy hypothesis);

The use of GnRH analogs in preserving ovarian function during chemotherapy
Background The literature has always been controversial on the use of gonadotropin-releasing hormone agonists in preserving fertility in women of childbearing age after chemotherapy; thereby, in this article, we will be discussing its use in preserving ...

Gonadotropin-releasing hormone antagonists [PDF]
Hypothalamic gonadotropin-releasing hormone (GnRH) is a decapeptide that stimulates pituitary synthesis and secretion of gonadotropins and, therefore, gonadal hormones. GnRH antagonists, of which thousands have been formulated, inhibit the hormone from binding to its receptor, inducing a pharmacological hypophysectomy.

Morphological evidence for enhanced kisspeptin and neurokinin B signaling in the infundibular nucleus of the aging man. [PDF]
Peptidergic neurons synthesizing kisspeptin (KP) and neurokinin B (NKB) in the hypothalamic infundibular nucleus have been implicated in negative sex steroid feedback to GnRH neurons. In laboratory rodents, testosterone decreases KP and NKB expression in

Estrone and estradiol concentrations in human ovaries, testes, and adrenals during the first two years of life [PDF]
To determine the origin of estrogens in infant blood, we measured estrone (E1) and estradiol (E2) in the gonads of 50 girls and 64 boys who died suddenly between birth and 2 yr of age as well as in the adrenals of 18 of these infant girls and 16 of the ...

pS6K1 as an efficacy marker of GnRH agonist with premenopausal breast cancer
Estradiol is a key factor for tumorigenesis and prognosis of hormone receptor-positive breast cancer. Adipocytes are one source of estradiol in patients with breast cancer. Recent studies have shown that phosphorylated ribosomal protein S6 kinase-1 plays

Protein and mRNA expression of gonadotropin-releasing hormone receptor in yaks during estrus
To demonstrate the role of gonadotropin-releasing hormone (GnRH) in yaks (Bos grunniens), we characterized the expression of gonadotropin-releasing hormone receptor (GnRHR) mRNA and protein.
