Activating and inactivating mutations of the human, rat, equine and eel luteinizing hormone/ chorionic gonadotropin receptors (LH/CGRs)

open access: yesJournal of Animal Reproduction and Biotechnology, 2021
Mutations in the luteinizing hormone/chorionic gonadotropin receptors (LH/CGRs), representatives of the G protein-coupled receptor family, have been rapidly identified over the last 20 years.

Sex Steroid Inhibition of LH Induction of the LH Receptor [PDF]

open access: yesJournal of Andrology, 1987
Testosterone and estrogen were tested as possible mediators of the prolactin‐dependent LH induction of LH receptors in hypophysectomized adult male rats. Animals were injected s.c. with saline, prolactin (100 μg/day), or combinations of testosterone (1 mg/day) or estrogen (1 mg/day) and prolactin for 7 days following a 7‐day period of hypophysectomy ...

Possible Relationship between Long-Term Adverse Health Effects of Gonad-Removing Surgical Sterilization and Luteinizing Hormone in Dogs

open access: yesAnimals, 2020
Spaying and neutering dogs is commonly used to prevent the birth of unwanted animals and eliminate the risk of reproductive diseases. However, removal of the gonads prevents the feedback of estrogen and testosterone on the pituitary and hypothalamus.

Effect of Exercise Training on Gene Expression of Adiponectin and its Receptors in Testicles and Sex Hormones in Diabetic Rats

open access: yesJournal of Biological Research, 2021
Adiponectin and its receptors are expressed in the male reproductive system, which play a role in regulating male sex hormones and fertility. Diabetes was induced by Streptozotocin-Nicotinamide (STZ-NA i.p) in rats and after performing the trainings ...

Optimization of whole-brain rabies virus tracing technology for small cell populations

open access: yesScientific Reports, 2021
The lateral hypothalamus (LH) is critically involved in the regulation of homeostatic energy balance. Some neurons in the LH express receptors for leptin (LepRb), a hormone known to increase energy expenditure and decrease energy intake.

Cis- and Trans-Activation of Hormone Receptors: the LH Receptor [PDF]

open access: yesMolecular Endocrinology, 2002
AbstractG protein-coupled receptors (GPCRs) accommodate a wide spectrum of activators from ions to glycoprotein hormones. The mechanism of activation for this large and clinically important family of receptors is poorly understood. Although initially thought to function as monomers, there is a growing body of evidence that GPCR dimers form, and in some

Discovery of new receptors regulating luteinizing hormone and follicle-stimulating hormone secretion by bovine gonadotrophs to explore a new paradigm for mechanisms regulating reproduction

open access: yesThe Journal of Reproduction and Development, 2020
Previous studies in the 1960s and 1970s have reported that both gonadotropin-releasing hormone (GnRH) and estradiol-activated nuclear estrogen receptors regulate gonadotropin secretion in women.
