A regulator of G Protein signaling, RGS3, inhibits gonadotropin-releasing hormone (GnRH)-stimulated luteinizing hormone (LH) secretion

open access: yesBMC Cell Biology, 2001
Background Luteinizing hormone secreted by the anterior pituitary gland regulates gonadal function. Luteinizing hormone secretion is regulated both by alterations in gonadotrope responsiveness to hypothalamic gonadotropin releasing hormone and by ...

Pituitary Luteinizing Hormone Analysis for Estimation of Time Passed Since Death: Biochemical Study (An Experimental Study) [PDF]

open access: yesMinia Journal of Medical Research, 2022
Background: The assessment of the time since death is one of the most prevalent and challenging concerns that a forensic practitioner tackles. While accurate determination is not always attainable, it is frequently possible to specify merely a broad ...

Microvesicle-mediated release of soluble LH/hCG receptor (LHCGR) from transfected cells and placenta explants [PDF]

open access: yes, 2011
Placental hCG and pitutary LH transduce signals in target tissues through a common receptor (LHCGR). We demonstrate that recombinant LHCGR proteins which include the hormone-binding domain are secreted from transfected cells and that natural LHCGR is ...

Expression of Luteinizing Hormone Receptor in the Gastrointestinal Tract in Patients with and without Dysmotility [PDF]

open access: yes, 2012
Leuprolide is a gonadotropin-releasing hormone (GnRH) analog which has been shown to reduce symptoms in patients with irritable bowel syndrome (IBS) and chronic intestinal pseudo-obstruction (CIPO).

Luteinizing Hormone Response to Pulsatile Luteinizing Hormone-Releasing Hormone in Prepubertal Heifers

open access: yesJournal of Dairy Science, 1986
The effects of 12 hourly 5-micrograms injections of luteinizing hormone-releasing hormone on luteinizing hormone release, were examined in 18 prepubertal Holstein heifers at 4, 7, or 10 mo of age. During a 6-h pretreatment period, mean serum luteinizing hormone concentrations and mean number of endogenous luteinizing hormone episodes per hour were not ...

Luteinizing Hormone in Frail Elderly Individuals [PDF]

open access: yesThe Egyptian Journal of Geriatrics and Gerontology, 1999
Background: The term "frailty" has been used clinically as a global concept to describe a condition, common in the old, of impaired strength, endurance, and balance, vulnerability to trauma and other stressors, and high risk for morbidity, disability ...

Proline-rich tyrosine kinase 2 mediates gonadotropin-releasing hormone signaling to a specific extracellularly regulated kinase-sensitive transcriptional locus in the luteinizing hormone beta-subunit gene [PDF]

open access: yes, 2007
G protein-coupled receptor regulation of gene transcription primarily occurs through the phosphorylation of transcription factors by MAPKs. This requires transduction of an activating signal via scaffold proteins that can ultimately determine the outcome

Data on Western blot and ELISA analysis of medaka (Oryzias latipes) follicle-stimulating hormone (Fsh) and luteinizing hormone (Lh) using recombinant proteins expressed with Pichia pastoris

open access: yesData in Brief, 2019
The gonadotropins follicle-stimulating hormone (Fsh) and luteinizing hormone (Lh) play essential roles in vertebrate reproduction. This article presents data on molecular weight validation of recombinant medaka (Oryzias latipes) (md) gonadotropins Fshβ ...
