Adult growth hormone (GH) deficiency is a well-described clinical syndrome with many features reminiscent of fibromyalgia. There is evidence that GH deficiency as defined in terms of a low insulin-like growth factor-1 (IGF-1) level occurs in approximately 30% of patients with fibromyalgia and is probably the cause of some morbidity. It seems most likely that impaired GH secretion in fibromyalgi...

Growth hormone (GH) initiates many of its growth-promoting actions by binding to GH receptors (GHR) and stimulating the synthesis and secretion of insulin-like growth factor-1 (IGF-1) from the liver and other sites. In this study, we used hepatocytes isolated from rainbow trout as a model system in which to determine the molecular signaling events of GH in fish. GH directly stimulated the phosp...

Growth hormone (GH) signaling is essential for postnatal linear bone growth, but the relative importance of GHs actions on the liver and/or growth plate cartilage remains unclear. The importance of liver derived insulin like-growth factor-1 (IGF-1) for endochondral growth has recently been challenged. Here, we investigate linear growth in Suppressor of Cytokine Signaling-2 (SOCS2) knockout mice...

BACKGROUND Estrogens regulate growth hormone (GH) secretion and modulate the tissue responsiveness to GH. After the menopause, and during ageing, a decline in GH secretion (somatopause) is physiologically observed. This article (i) provides a brief overview of the different regulators of GH secretion, (ii) reviews the mechanisms involved in age-related changes in GH concentrations, with particu...

1. Introduction It is not clear how different portions of the capsuloligaments and muscles contribute to GH stability. Since GH instabilities occur frequently in various shoulder injuries, it is important to understand the restraining forces provided by various structures in the GH-joint. A better understanding of the GH stiffness will also help improve existing shoulder models by including GH ...

Obesity and its related factors are known to suppress the secretion of growth hormone (GH). We aimed to evaluate the influence of body mass index (BMI) on the peak GH response to provocative testing in short children without GH deficiency. We conducted a retrospective review of medical records of 88 children (2-15 yr old) whose height was less than 3 percentile for one's age and sex, with norma...

GH expression in mammary tumors has been related to the increase and spreading of cell proliferation. Using the MCF-7 human breast adenocarcinoma cell line, it has been demonstrated that autocrine GH-stimulated mammary carcinoma cell proliferation decreased the apoptosis rate and enhanced cell spreading. Surprisingly, no data are available about the presence of Pit-1 (the main pituitary regulat...

BACKGROUND Patients with Prader-Willi syndrome (PWS) have a cognitive impairment. Growth hormone (GH) treatment during childhood improves cognitive functioning, while cognition deteriorates in GH-untreated children with PWS. Cessation of GH treatment at attainment of adult height (AH) might deteriorate their GH-induced improved cognition, while continuation might benefit them. We, therefore, in...

To investigate the mechanisms behind the water- and sodium-retaining effects of growth hormone (GH), we studied the effect of GH on 1) water and sodium homeostasis, 2) the renin-angiotensin-aldosterone system (RAAS), and 3) lithium clearance (C(Li)) with and without concomitant prostaglandin (PG) synthesis inhibition with ibuprofen. GH administration for 6 days induced a significant increase in...
