Genetics and Luteinizing Hormone Receptors
1994Testicular luteinizing hormone receptors (LH-Rs) that bind either LH or human chorionic gonadotropin (hCG) are required for the differentiation of the Leydig cell (1). This is indicated by the correlation between the onset of Leydig cell differentiation and the appearance of hCG during the development of the human fetus. The number of Leydig cells also

On the Structure of the Luteinizing Hormone/Chorionic Gonadotropin Receptor*
Endocrine Reviews, 1989In this review we have tried to argue that the evidence indicating that the LH/CG receptor is composed of a single polypeptide is stronger than the evidence indicating that the LH/CG receptor is a more complex structure composed of several subunits.

Receptors | Thyroid-Stimulating Hormone/Luteinizing Hormone/Follicle-Stimulating Hormone Receptors
2021The thyroid-stimulating hormone receptor (TSHR), luteinizing hormone receptor (LHCGR), and follicle-stimulating hormone receptor (FSHR) are collectively referred to as the glycoprotein hormone receptors because they bind structurally similar glycoprotein hormones.

Ontogeny of the gonadal receptor for luteinizing hormone in the pig
Theriogenology, 1990Homogenates of porcine ovaries and testes collected between 70 d post coitum and 42 d post partum were incubated with radiolabelled human chorionic gonadotropin (hCG) to determine the presence and relative amounts of luteinizing hormone/human chorionic gonadotropin (LH/hCG) receptors. Specific binding of (125)I-hCG to ovaries and testes occurred at all

Chicken hypothalamic LHRH, which was recently structurally characterized, was synthesized by solid-phase methodology, characterized, and tested for LH-releasing activity using anterior pituitary cells from chickens and sheep, as well as for binding to chicken and rat anterior pituitary membrane receptors.

LHRH, via inducing inordinately high LH levels, can disrupt pregnancy in the rat. Based on studies indicating that LH can reduce gonadal content of its own receptor and thereby modify LH-dependent steroidogenesis, the effect of contragestational LHRH treatment on ovarian LH receptor dynamics was investigated.

Specificity of the Immunocytochemical Luteinizing Hormone-Releasing Hormone Receptor Reaction
Endocrinology, 1978Affinity-purified anti-LHRH, affinity-purified LHRH-anti-LHRH complex, as well as antisera depleted of anti-LHRH by solid phase immunoabsorption were used to test the specificity of the immunocytochemical approach for detection of receptor-bound LHRH.

Quantitative immunocytochemistry of pituitary receptors for luteinizing hormone-releasing hormone
Cell and Tissue Research, 1975In Araldite sections of male rat pituitaries, stained after embedding by the unlabeled antibody enzyme method with antisera to native luteinizing hormone-releasing hormone (LH-RH) or LH-RH azo-conjugated to bovine serum albumin, localization is confined mainly to the interior of the large, and to a lesser extent to that of the small, secretion granules

Distribution of luteinizing hormone-releasing hormone receptors in the rat ovary
Regulatory Peptides, 1982The distribution of luteinizing hormone-releasing hormone (LHRH) receptors was studied in the adult rat ovary using autoradiography after injection of the stable LHRH agonist 125I-labelled [D-Ser(TBU)6,des-Gly-NH2(10)]LHRH ethylamide (Buserelin) and by radioreceptor assay using the same tracer.

Prolactin Inhibits Pituitary Luteinizing Hormone-Releasing Hormone Receptors in the Rat
Endocrinology, 1982Pituitary LHRH receptors were studied in intact immature and mature female rats as well as in adult castrated animals of both sexes under experimental conditions leading to marked alterations of plasma PRL levels. Implantation of three anterior pituitary glands under the kidney capsule on the morning of estrus prevented the increase in pituitary LHRH ...
