Energy homeostasis and gastric emptying in ghrelin knockout mice.
To elucidate the role of endogenous ghrelin in the regulation of energy homeostasis and gastric emptying, ghrelin knockout mice (ghrelin(-/-)) were generated. Body weight, food intake, respiratory quotient, and heat production (indirect calorimetry), and gastric emptying ((14)C breath test) were compared between ghrelin(+/+) and ghrelin(-/-) mice. In both strains, the effect of exogenous ghreli...
متن کاملGhrelin and obestatin in human neuroendocrine tumors: expression and effect on obestatin levels after food intake.
BACKGROUND Ghrelin and obestatin are derived from the same peptide hormone precursor and are mainly produced by the gastric mucosa. Ghrelin is involved in many biological processes, whereas the physiological function of obestatin needs further investigation. The aims of the present study were to establish the incidence of ghrelin- and obestatin-immunoreactive cells in a comprehensive panel of h...
متن کاملPeripheral urocortin inhibits gastric emptying and food intake in mice: differential role of CRF receptor 2.
Intraperitoneal urocortin inhibits gastric emptying and food intake in mice. We investigated corticotropin-releasing factor receptor (CRF-R) subtypes involved in intraperitoneal urocortin actions using selective CRF-R antagonists. Gastric emptying was measured 2 h after a chow meal, and food intake was measured hourly after an 18-h fast in mice. Urocortin (3 microg/kg ip) inhibited gastric empt...
متن کاملEffect of peripheral administration of cholecystokinin on food intake in apolipoprotein AIV knockout mice.
Apolipoprotein AIV (apo AIV) and cholecystokinin (CCK) are satiation factors secreted by the small intestine in response to lipid meals. Apo AIV and CCK-8 has an additive effect to suppress food intake relative to apo AIV or CCK-8 alone. In this study, we determined whether CCK-8 (1, 3, or 5 μg/kg ip) reduces food intake in fasted apo AIV knockout (KO) mice as effectively as in fasted wild-type...
متن کاملCentral effect of histamine and peripheral effect of histidine on food intake in rabbits
Histidine is an amino acid precursor of neuronal histamine. It is evident that peripheral injection of histidine produces effects that resemble to centrally administered histamine. The aim of the present study was to compare the effects of intracerebroventricular (ICV) injection of histamine and inraperitoneal (IP) injection of histidine on food intake in rabbits. ICV injections of histamine (1...
