Growth hormone (GH) gene expression predominantly occurs in the pituitary gland, although it also occurs in many extrapituitary sites, including the brain. The cellular location and ontogeny of neural GH production is, however, largely unknown. This has therefore been determined during chick embryogenesis. In chicks, the brain develops from the neural tube at embryonic day (ED) 3. At this age, ...

CONTEXT Treatment of adult GH deficiency (AGHD) with daily injections of GH results in decreased adipose mass, increased lean body mass (LBM), increased bone mineral density, and improved quality of life. OBJECTIVE This study seeks to determine whether a depot preparation of GH given every 14 d would lead to comparable decreases in trunk adipose tissue as daily GH. DESIGN This open-label, r...

The effects of long term in vitro exposure witil octreotide of human GH secreting pituitary adenoma cells were investigated on GH release, intracellular GH concentrations, and GH mRNA levels. Incubation of tile adenoma cells for 4 days witil 10nM octreotide induced a dose-dependent inhibition of GH release, while in parallel an increase (maximal increase varying between 24 and 517%) in the intr...

Growth Hormone (GH) is an important and powerful metabolic hormone that is secreted in a pulsatile pattern from cells in the anterior pituitary, influenced by several normal and pathophysiological conditions. Human GH was first isolated in the 1950s and human derived cadaveric GH was initially used to treat patients with GH deficiency. However, synthetic recombinant GH has been widely available...

We have investigated whether a reduced MCR of GH in women will account for their higher serum GH concentrations premenopausally compared with those in men. To this end, we directly compared the half-life (t 1/2) of GH and its volume of distribution (Vo) in 13 young men and 6 comparably aged women, each evaluated at three stages of the normal menstrual cycle (viz. the early follicular, late foll...

Tomato (Solanum lycopersicum) is commonly cultivated in the greenhouse and open fields. Organic conventional nutrients are two common inputs for crops. Since there different methods producing tomatoes, four most important scenarios were selected, focusing on types of nutrient management options (organic conventional), cultivation (open field greenhouse). The organic (scenario one: GH-O), two: G...

The aim of this study was to investigate the direct effects of growth hormone (GH) on production and secretion of apolipoprotein B (apoB)-containing lipoproteins from hepatocytes. Bovine GH (5-500 ng/ml) was given for 1 or 3 days to rat hepatocytes cultured on laminin-rich matrigel in serum-free medium. The effects of GH were compared with those of 3 nM insulin and 500 microM oleic acid. GH inc...

Background. Growth hormone (GH) and insulin-like growth factor (IGF-1) are fundamental in skeletal growth during puberty and bone health throughout life. GH increases tissue formation by acting directly and indirectly on target cells; IGF-1 is a critical mediator of bone growth. Clinical studies reporting the use of GH and IGF-1 in osteoporosis and fracture healing are outlined. Methods. A Pubm...
