Enkephalins and Pituitary Hormone Release Modification of Responsiveness to LHRH

Hormone Research, 2008
An intraperitoneal injection of leucine-enkephalin into rats stimulates gonadotropin and prolactin release. To elucidate the mechanism of this releasing property of leucine-enkephalin, rat hemipituitaries were incubated with either enkephalin alone or enkephalin in combination with LHRH.

A Receptor in Pituitary and Hypothalamus That Functions in Growth Hormone Release

Science, 1996
Small synthetic molecules termed growth hormone secretagogues (GHSs) act on the pituitary gland and the hypothalamus to stimulate and amplify pulsatile growth hormone (GH) release. A heterotrimeric GTP-binding protein (G protein)-coupled receptor (GPC-R) of the pituitary and arcuate ventro-medial and infundibular hypothalamus of swine and humans was ...

Effects of Thymosin Alpha-1 on Pituitary Hormone Release

Neuroendocrinology, 2008
The thymosins are a family of hormone-like products of epithelial cells of the thymus which are important in maintenance and function of the immune system. Thymosin fraction 5, a partially purified extract of calf thymus, can influence pituitary hormone release.

Effect of exogenous glucagon on pituitary polypeptide hormone release

Metabolism, 1970
Abstract Anterior pituitary hormone secretion following administration of crystalline glucagon was studied in three phases, i.e., after subcutaneous injection, after intravenous injection, and after intravenous injection during constant glucose infusion.

Galanin modulates pituitary hormones release.

Neuro endocrinology letters, 2006
Galanin and its receptors are widely distributed within the central and peripheral nervous system, especially in hypothalamus including preoptic area, paraventricular nucleus (PVN), supraoptic nucleus (SON) and median eminence. Galanin plays an important role in the control of food intake, energy expenditure, reproduction, water balance and various ...

Role of Monokines in Control of Anterior Pituitary Hormone Release

1990
It has long been known that endogenous pyrogen, released as a result of injection of typhoid vaccine or in response to infection, produces fever and increases ACTH secretion. Recent studies have indicated that endogenous pyrogen is, at least in part, IL-1. This monokine has now been shown to activate the release of ACTH by a hypothalamic mechanism with

Stimulation of luteinising hormone release by luteinising hormone-releasing hormone in the porcine anterior pituitary: The role of cyclic AMP

Molecular and Cellular Endocrinology, 1978
Abstract Cells dissociated from porcine pituitary glands have been used to examine the relationship between cyclic AMP levels and the stimulation of luteinising hormone (LH) secretion by luteinising hormone-releasing hormone (LHRH). It has been shown that while dibutyryl cyclic AMP and theophylline have a modest and, under some conditions, an ...

Localization of Growth Hormone-Releasing Hormone in the Human Hypothalamus and Pituitary Stalk*

The Journal of Clinical Endocrinology & Metabolism, 1986
The localization of the recently identified GH-releasing hormone (GHRH) in the human hypothalamus and pituitary stalk was determined by microdissection techniques and a specific RIA for GHRH. The highest concentrations of GHRH immunoreactivity (IR-GHRH) in the hypothalamus were found in the area of the infundibular nucleus (83 +/- 4 ng/mg protein ...

Action of luteinizing hormone-releasing hormone and synthesis of prostaglandin in the pituitary gland

Prostaglandins, 1975
The possibility that prostaglandin E2 (PGE2) may play a role in luteinizing hormone (LH) release was examined using an in vitro model. Addition of luteinizing hormone-releasing hormone (LH-RH) to the culture medium stimulated cyclic AMP accumulation and LH-release by incubated hemipituitaries, but did not affect the level of PGE2 or prostaglandin ...

The response of the pituitary gland to luteinizing hormone-releasing hormone in broody bantams

General and Comparative Endocrinology, 1981
The concentration of plasma LH increased significantly (P < 0.001) after an iv injection of 20 μg LHRH/kg body wt in out-of-lay, laying, incubating, and brooding bantams. The increase in out-of-lay (2.6 ± 0.4 [SEM] ng/ml, n = 12) and laying (1.8 ± 0.3 ng/ml, n = 6) birds was significantly less (P < 0.05) than in incubating (5.0 ± 0.8 ng/ml, n = 10) or ...
