Expression of human luteinizing hormone (LH) receptor : interaction with LH and chorionic gonadotropin from human but not equine, rat, and ovine species

, 1991
Studies on human LH receptors are difficult due to the limited availability of clinical samples. Recent cloning of rat and porcine LH receptor cDNAs indicated that these binding sites are single polypeptides of the G-protein-coupled receptor family with ...

Impaired ovulation by 2,3,7,8 tetrachlorodibenzo-p-dioxin (TCDD) in immature rats treated with equine chorionic gonadotropin.

, 2001
Several studies have established that 2,3,7,8 tetrachloro-p-dioxin (TCDD) blocks ovulation. The main purpose of this study was to determine if induced ovulation was delayed temporarily by TCDD. The ovulation model used was that of the gonadotropin-primed

Comparative effects of sub-stimulating concentrations of non-human versus human Luteinizing Hormones (LH) or chorionic gonadotropins (CG) on adenylate cyclase activation by forskolin in MLTC cells

, 2018
International audienceWe have compared various Luteinizing Hormone (LH) and Chorionic Gonadotropin (CG) preparations from non-human and human species in their ability to synergize with 10 mu M forskolin (FSK) for cyclic AMP intracellular accumulation, in

Effects of a Gonadotropin Mixture on Reproductive Success in Progesterone- Treated Non-Lactating Anestrous Ewes

, 2013
Using exogenous gonadotropins as part of an estrous induction protocol can have beneficial effects on fertility in ewes bred out-of-season. Few studies have evaluated the efficacy of P.G.

The ß104-109 sequence is essential for the secretion of correctly folded single-chain ßα horse LH/CG and for its FSH activity

, 2009
International audienceThe dual LH and FSH activity of the equine LH (eLH)/equine chorionic gonadotropin (eCG) in heterologous species makes eLH/CG a good model to study structure/function relationships of gonadotropins.

Active immunization of prepubertal boars against testosterone: testicular and endocrine responses at 14 months of age.

, 1985
Thirteen crossbred boars were immunized at 1 mo of age against either testosterone-3-oxime-equine serum albumin (treated boars) or equine serum albumin (control boars) to test the hypothesis that active immunization against testosterone stimulates ...

Effect of altering the ratio of exogenous gonadotropins on reproductive performance of primiparous sows during the seasonal infertility period

, 2018
At weaning, 150 primiparous sows were assigned sequentially to receive 400 IU equine chorionic gonadotropin (eCG) with 200 IU human chorionic gonadotropin (hCG) (Gn600), or 400 IU eCG with 400 IU hCG (Gn800), or served as untreated controls.
