In type 2 diabetes, glucagon levels are elevated in relation to the prevailing insulin and glucose levels. The relative hyperglucagonemia is linked to increased hepatic glucose output (HGO) and hyperglycemia. Antagonizing the effects of glucagon is therefore considered an attractive target for treatment of type 2 diabetes. In the current study, effects of eliminating glucagon signaling with a g...
The term glucagon was coined by Kimball and an immunoreactant in common with glucagon (gut Murlin (1923) to describe a hyperglycaemic subGLIs). The extensive similarities between the stance which they had partially purified from an sequences of glucagon, VIP, secretin, and GIP have extract of bovine pancreas. In 1953, Staub et al. been discussed elsewhere in these proceedings. The crystallised ...
[Studies on the fetal and neonatal secretion of glucagon and the development of glucagon receptors].
In order to clarify the potential roles of glucagon for energy induction during the perinatal period, the developmental changes of serum glucagon concentration, the ontogenesis of hepatic glucagon receptor and glucagon-sensitive adenylate cyclase system were estimated in comparison with insulin in rats. In fetal rats on day 18 to 20 gestation, serum glucose levels and hepatic glycogen contents ...
To evaluate the mechanism and role of hyperglucagonemia in the carbohydrate intolerance of uremia, 19 patients with chronic renal failure (12 of whom had undergone chronic hemodialysis for at least 11 mo) and 35 healthy control subjects were studied. Plasma glucagon, glucose, and insulin were measured in the basal state, after glucose ingestion (100 g), after intravenous alanine (0.15 g/kg), an...
In fasting-refeeding experiments glucagon was found to inhibit the induction of rat liver glucose-&P dehydrogenase. The kinetics of induction in the presence of glucagon indicated that the hormone decreased the rate of enzyme synthesis without altering the rate of enzyme degradation. Immunochemical titration of the amount of glucose-6-P dehydrogenase protein present in control and glucagon trea...
Hypersecretion of glucagon contributes to the dysregulation of glucose homeostasis in diabetes. To clarify the underlying mechanism, glucose-regulated glucagon secretion was studied in mouse pancreatic islets and clonal hamster In-R1-G9 glucagon-releasing cells. Apart from the well-known inhibition of secretion with maximal effect around 7 mmol/l glucose, we discovered that mouse islets showed ...
Brown adipose tissue (BAT) glucagon level was higher in cold-acclimated rats (CA) than in warm controls (WC). Noradrenaline (NA) injection increased BAT glucagon levels in both WC and CA with increases in plasma glucagon levels. The magnitude of increase was significantly greater in CA for plasma glucagon, while it did not differ for BAT between groups. However, BAT glucagon was kept at a highe...
Defect in the function of pancreatic cells is one key pathophysiological factors type 2 diabetes, particular, an imbalance between secretion insulin and glucagon, as well a decrease efficiency converting proinsulin into insulin, often observed. The aim work was to compare characteristics secretory alpha beta 43 patients with decompensated diabetes mellitus when using new classes anti-diabetic d...
Receptor recognition by the Asp(3) residues of vasoactive intestinal peptide and secretin requires the presence of a lysine residue close to the second transmembrane helix (TM2)/first extracellular loop junction and an ionic bond with an arginine residue in TM2. We tested whether the glucagon Gln(3) residue recognizes the equivalent positions in its receptor. Our data revealed that the binding ...
