BACKGROUND AND AIMS The gastric hormone ghrelin has been reported to stimulate food intake, increase weight gain, and cause obesity but its precise physiological role remains unclear. We investigated the long term effects of gastrectomy evoked ghrelin deficiency and of daily ghrelin injections on daily food intake, body weight, fat mass, lean body mass, and bone mass in mice. METHODS Ghrelin ...
The peptide hormone ghrelin is released from a distinct group of gastrointestinal cells in response to caloric restriction, whereas its levels fall after eating. The mechanisms by which ghrelin secretion is regulated remain largely unknown. Here, we have used primary cultures of mouse gastric mucosal cells to investigate ghrelin secretion, with an emphasis on the role of glucose. Ghrelin secret...
Ghrelin is a gut peptide that when acylated is thought to stimulate appetite. Circulating ghrelin concentrations could potentially be used as a predictor of DMI in cattle. The objective of this experiment was to determine the association of circulating ghrelin concentrations with DMI and other production traits. Steers and heifers were fed a finishing diet, and individual intake was recorded fo...
Ghrelin is the natural ligand of the growth hormone secretagogue receptor (GHS-R1a). Ghrelin is a 28 amino acid peptide possessing a unique acylation on the serine in position 3 catalyzed by ghrelin O-acyltransferase (GOAT). Ghrelin stimulates growth hormone secretion, but also appetite, food intake, weight gain, and gastric emptying. Ghrelin is involved in weight regulation, obesity, type 2 di...
UNLABELLED There are no effective antifibrotic therapies for patients with liver diseases. We performed an experimental and translational study to investigate whether ghrelin, an orexigenic hormone with pleiotropic properties, modulates liver fibrogenesis. Recombinant ghrelin was administered to rats with chronic (bile duct ligation) and acute (carbon tetrachloride) liver injury. Hepatic gene e...
Ghrelin, a peptide purified from the stomach, is an endogenous ligand for the growth hormone secretagogue receptor (GHS-R) and potently stimulates growth hormone release from the pituitary. Ghrelin is modified with an n-octanoyl group at Ser(3). This modification is essential for the activity of ghrelin. Previously, it was not known whether other ligands for GHS-R existed. Here, we report the p...
To examine the gene expression of ghrelin, a growth hormone releasing and appetite stimulating hormone from stomach, we constructed human ghrelin promoter-reporter vectors and analyzed the promoter activity. The ghrelin promoter activity was high when cultured cells that express ghrelin mRNA endogenously like TT or ECC10 cells were used, indicating that these cells contain factors necessary for...
In structure, ghrelin resembles motilin. The two peptides are considered to be members of the motilin-ghrelin peptide family. Motilin is considered to be an endocrine regulator of the interdigestive migrating contractions, the fasted motor pattern in the gastrointestinal (GI) tract. It has been reported that ghrelin stimulates GI motility. The gastrokinetic capacity of ghrelin has been well doc...
background ghrelin and obestatin are orexigenic and anorexigenic peptides, respectively. it appears that an accurate balance between theses peptides is important for regulating energy homeostasis and body weight. objectives the aim of this study was to identify the possible mechanisms by which circuit resistance training influences energy homeostasis and weight control. patients and methods twe...
conclusions igf-1 has the most significant effect on intrauterine growth. acylated ghrelin is detectable in cord blood and correlated with birth weight, suggesting a role in intrauterine development, but its level is not affected by intrauterine growth retardation. results no significant differences were observed in ghrelin and gh concentrations between sga and aga infants. however, igf-1 level...
