The rotational diffusion of LH receptors differs when receptors are occupied by hCG versus LH and is increased by cytochalasin D

Biochimica et Biophysica Acta (BBA) - Molecular Cell Research, 1997
We have examined the rotational diffusion of the luteinizing hormone (LH) receptors binding human chorionic gonadotropin (hCG) or ovine luteinizing hormone (oLH) in MA-10 Leydig tumor cells using time-resolved phosphorescence anisotropy techniques. LH receptors binding erythrosin isothiocyanate (ErITC)-derivatized oLH were rotationally mobile with ...

The Expression of Serum Antibodies against Gonadotropin-releasing Hormone (GnRH1), Progonadoliberin-2, Luteinizing Hormone (LH), and Related Receptors in Patients with Gastrointestinal Dysfunction or Diabetes Mellitus [PDF]

Drug Target Insights, 2014
Gonadotropin-releasing hormone (GnRH) 1 and 2 and luteinizing hormone (LH) receptors have been described in the gastrointestinal tract. We have previously demonstrated antibodies in serum against GnRH1 in patients with gastrointestinal dysfunction and ...

Slc12a8 in the lateral hypothalamus maintains energy metabolism and skeletal muscle functions during aging

Cell Reports, 2022
Summary: Sarcopenia and frailty are urgent socio-economic problems worldwide. Here we demonstrate a functional connection between the lateral hypothalamus (LH) and skeletal muscle through Slc12a8, a recently identified nicotinamide mononucleotide ...

Effect of Estrogen Progesterone LH and FSH on Oxidant and Antioxidant Parameters in Rat Uterine Tissue [PDF]

International Journal of Fertility and Sterility, 2009
Background To attain whether the effects of low and high doses of estrogen progesterone luteinizing hormone (LH) and follicle stimulating hormone (FSH) in acute and chronic administration were related to oxidant and antioxidant parameters in rat uterine ...

Membrane-initiated actions of estradiol (E2) in the regulation of LH secretion in ovariectomized (OVX) ewes

Reproductive Biology and Endocrinology, 2010
Background We demonstrated that E2 conjugated to BSA (E2BSA) induces a rapid membrane-initiated inhibition of LH secretion followed hours later by a slight increase in LH secretion. Whether these actions of E2BSA are restricted to the pituitary gland and

Changes in the Orexin System in Rats Exhibiting Learned Helplessness Behaviors

Brain Sciences, 2021
Orexin-A (OX-A) and orexin-B (OX-B) are neuropeptides produced in the hypothalamus. Preclinical and clinical studies suggest that depression and anxiety are associated with the orexin system.

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

, 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 ...

Lateral hypothalamus involvement in control of stress response by bed nucleus of the stria terminalis endocannabinoid neurotransmission in male rats

Scientific Reports, 2021
The endocannabinoid neurotransmission acting via local CB1 receptor in the bed nucleus of the stria terminalis (BNST) has been implicated in behavioral and physiological responses to emotional stress.

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

Drug Target Insights, 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).
