The action of the C-terminal octapeptide of cholecystokinin and related peptides on pancreatic exocrine secretion.
The effect of the C-terminal octapeptide of cholecystokinin-pancreozymin (CCK-PZ), caerulein, and the C-terminal tetrapeptide of gastrin on pancreatic secretion of fluid, electrolyte, amylase, and protein was studied in anaesthetized dogs prepared with pancreatic fistulae. Against background stimulation of fluid secretion with submaximal doses of secretin, all the polypeptides produced a qualit...
متن کاملPurification and sequence of rat oxyntomodulin.
Structural information about rat enteroglucagon, intestinal peptides containing the pancreatic glucagon sequence, has been based previously on cDNA, immunologic, and chromatographic data. Our interests in testing the physiological actions of synthetic enteroglucagon peptides in rats required that we identify precisely the forms present in vivo. From knowledge of the proglucagon gene sequence, w...
متن کاملThe glucagon-like peptide-1 receptor agonist oxyntomodulin enhances beta-cell function but does not inhibit gastric emptying in mice.
The proglucagon gene gives rise to multiple peptides that play diverse roles in the control of energy intake, gut motility, and nutrient disposal. Glucagon-like peptide-1 (GLP-1), a 30-amino-acid peptide regulates glucose homeostasis via control of insulin and glucagon secretion and by inhibition of gastric emptying and food intake. Oxyntomodulin (OXM) a 37-amino-acid peptide also derived from ...
متن کاملInhibition of meal stimulated gastric acid secretion by an octapeptide somatostatin analogue SMS 201-995.
A dose response study of the effect of an octapeptide somatostatin analogue, SMS 201-995, on meal stimulated gastric acid secretion was carried out in 12 healthy volunteers. Infusion of SMS 201-995 in a dose of 50 pmol/kg/h almost completely abolished the acid response to the meal. Pl-gastrin was significantly decreased during infusion of 10 pmol/kg/h of SMS 201-995 and insulin was significantl...
متن کاملCholecystokinin and its COOH-terminal octapeptide in the pig brain.
Two components--one resembling intact cholecystokinin in size and charge and immunologic specificity, and the other resembling the COOH-terminal octapeptide of cholecystokinin--have been found in extracts of the pig cerebral cortex. The relative concentrations of the two peptides in the extracts were dependent on the extractant, boiling 0.1 M HCl being more effective than boiling water for the ...
