Ghrelin is an acylated peptide hormone secreted primarily from endocrine cells in the stomach. The major active form of ghrelin is a 28-amino acid peptide with an n-octanoyl modification at Ser(3) (n-octanoyl ghrelin), which is essential for its activity. In addition to n-octanoyl ghrelin, other forms of ghrelin peptide exist, including des-acyl ghrelin, which lacks an acyl modification, and ot...
The aim of the present study was to investigate the postprandial effect of diet composition on circulating acylated ghrelin levels in healthy women. A randomized cross-over study of three experimental treatments was performed. A total of 11 healthy young women of normal body weight completed the study. All 11 subjects consumed three iso-energetic meals of different macronutrient composition, a ...
BACKGROUND/AIMS The gastric peptide ghrelin, an endogenous ligand for growth-hormone secretagogue receptor, has two major molecular forms: acylated ghrelin and desacyl ghrelin. Acylated ghrelin induces a positive energy balance, while desacyl ghrelin has been reported to be devoid of any endocrine activities. The authors examined the effects of desacyl ghrelin on energy balance. METHODS The a...
Bariatric surgery improves non-alcoholic fatty liver disease (NAFLD). Our aim was to investigate the potential role of ghrelin isoforms in the resolution of hepatic steatosis after sleeve gastrectomy, a restrictive bariatric surgery procedure, in diet-induced obese rats. Male Wistar rats (n = 161) were subjected to surgical (sham operation and sleeve gastrectomy) or dietary interventions [fed a...
INTRODUCTION Cystic fibrosis (CF) is a common genetic disorder as a result of mutation in the CF transmembrane conductance regulator gene. Weight loss in CF patients seems to be multifactorial and metabolic factors, inflammation, recurrent infections and poor appetite are possible candidates. Ghrelin affects energy hemostasis by stimulating growth hormone secretion, glucose and lipid metabolism...
We have recently shown that a polyphenol-rich insoluble dietary fibre preparation from carob pulp (Ceratonia siliqua L; carob fibre) decreased postprandial acylated ghrelin, TAG and NEFA during an acute liquid meal challenge test. However, delayed effects of carob fibre consumption are unknown. Therefore, a randomized controlled crossover study in nineteen healthy volunteers consuming foods wit...
Ghrelin is an acylated peptidyl gastric hormone acting on the pituitary and hypothalamus to stimulate appetite, adiposity, and growth hormone release, through activation of growth hormone secretagogue receptor (GHSR)-1a receptor. Moreover, ghrelin features several activities such as inhibition of apoptosis, regulation of differentiation, and stimulation or inhibition of proliferation of several...
BACKGROUND Acylated ghrelin, biologically active form of ghrelin, activates growth hormone (GH) secretagogue receptor 1a and play a role in regulating of energy balance. The purpose of this study was to survey relationships between acylated ghrelin with GH, insulin resistance, lipid profile, and cardio respiratory function in lean and obese men. METHODS Nineteen obese men (body mass index 31....
BACKGROUND AND OBJECTIVES The prevalence of obesity in Indonesia has increasing. We have assessed the relationship between plasma acylated ghrelin hormone and self-reported appetite ratings (hunger and desire to eat) in obese and normal weight men. METHODS AND STUDY DESIGN Thirty-two men participated in an experimental study, where acylated ghrelin and self-reported appetite ratings were comp...
The aim of this study was to investigate the differences in associations of serum acylated and des-acylated ghrelin, peptide YY (PYY) and leptin levels with physical activity (PA) and cardiorespiratory fitness (CReF) in adolescent boys (mean age of 14.0 years) with overweight (OWB; n=55) and with normal weight (NWB; n=154). METHODS Total PA was measured by 7-day accelerometry (counts/min) and...
