Growth hormone (GH) released from pituitary under direct control of hypothalamic releasing (i.e., GHRH) and inhibiting (i.e., sst or SRIF) hormones is an anabolic hormone that regulates metabolism of proteins, fats, sugars and minerals in mammals. Cyril Bowers' discovery of GH-releasing peptide (GHRP-6) was followed by a search for synthetic peptide and(More)
Research on the mechanism for growth hormone secretagogue (GHS) induction of growth hormone secretion led to the discovery of the GHS receptor (GHS-R) and later to ghrelin, an endogenous ligand for GHS-R. The ability of ghrelin to induce an increase in the intracellular Ca(2+) concentration - [Ca(2+)](i) - in somatotropes was examined in dispersed porcine(More)
The effects of a GH secretagogue, L-692,585 (L-585), and human GH-releasing hormone (hGHRH) on calcium transient and GH release were investigated in isolated porcine pituitary cells using calcium imaging and the reverse hemolytic plaque assay (RHPA). Somatotropes were functionally identified by the application of hGHRH. All cells that responded to hGHRH(More)
Leptin, the product of the obese gene, is a protein that is secreted primarily from adipocytes. Leptin can influence the function of the pituitary gland through its action on the hypothalamus, but it can also directly act at the level of the pituitary gland. The ability of leptin to induce an increase in intracellular Ca2+ concentration ([Ca2+]i) in(More)
Multiple secretagogues stimulate the release of growth hormone (GH). The present studies examined the ability of chicken somatotropes to respond to GH secretagogues with increased intracellular calcium concentrations ([Ca2+]i). It was hypothesized that there are subsets of the somatotrope population with different responsiveness to the various(More)
There has been extensive research of the anterior pituitary gland of livestock and poultry due to the economic (agricultural) importance of physiological processes controlled by it including reproduction, growth, lactation and stress. Moreover, farm animals can be biomedical models or useful in evolutionary/ecological research. There are for multiple sites(More)
