Effect of trauma on plasma glucagon and insulin concentrations in sheep. (1/3774)

Portal plasma glucagon and insulin concentrations were measured before and after acute trauma (liver biosy). The trauma was sufficient to increase glucagon concentrations and depress insulin concentrations. These changes were associated with a marked hyperglycemia. Infusion of glucagon was insufficient to prevent stress inhibition of insulin secretion. The stimulation of glucagon secretion and inhibition of insulin secretion were of about one hour duration. These findings indicate that glucagon and insulin in conjunction with the nervous system may play an important role in the development of stress related hyperglycemia.  (+info)

Effects of glucagon and insulin on lipolysis and ketogenesis in sheep. (2/3774)

The hepatic and portal productions of acetoacetate and beta-hydroxybutyrate and lipolysis were studied in normal and insulin-controlled alloxan-diabetic sheep. Since hyperinsulinemia is associated with glucagon administration, the latter group of sheep were used to maintain constant plasma insulin levels. After control values were obtained glucagon was infused intraportally at 90 mug/hr for two hours. The ketone body production by portal drained viscera was not significantly affected by glucagon. In alloxanized sheep, glucagon significantly (P less than 0.01) increased net hepatic production of acetoacetate (from -0.54 +/- 0.08 to 0.46 +/- 0.07 g/hr). Lipolysis also increased. However, in the normal sheep, hyperinsulinemia prevented any stimulatory effect of glucagon on hepatic ketogenesis and lipolysis. Therefore, while glucagon appears capable of stimulating ketogenesis andlipolysis, these effects are readily suppressed by insulin.  (+info)

Leptin suppression of insulin secretion and gene expression in human pancreatic islets: implications for the development of adipogenic diabetes mellitus. (3/3774)

Previously we demonstrated the expression of the long form of the leptin receptor in rodent pancreatic beta-cells and an inhibition of insulin secretion by leptin via activation of ATP-sensitive potassium channels. Here we examine pancreatic islets isolated from pancreata of human donors for their responses to leptin. The presence of leptin receptors on islet beta-cells was demonstrated by double fluorescence confocal microscopy after binding of a fluorescent derivative of human leptin (Cy3-leptin). Leptin (6.25 nM) suppressed insulin secretion of normal islets by 20% at 5.6 mM glucose. Intracellular calcium responses to 16.7 mM glucose were rapidly reduced by leptin. Proinsulin messenger ribonucleic acid expression in islets was inhibited by leptin at 11.1 mM, but not at 5.6 mM glucose. Leptin also reduced proinsulin messenger ribonucleic acid levels that were increased in islets by treatment with 10 nM glucagon-like peptide-1 in the presence of either 5.6 or 11.1 mM glucose. These findings demonstrate direct suppressive effects of leptin on insulin-producing beta-cells in human islets at the levels of both stimulus-secretion coupling and gene expression. The findings also further indicate the existence of an adipoinsular axis in humans in which insulin stimulates leptin production in adipocytes and leptin inhibits the production of insulin in beta-cells. We suggest that dysregulation of the adipoinsular axis in obese individuals due to defective leptin reception by beta-cells may result in chronic hyperinsulinemia and may contribute to the pathogenesis of adipogenic diabetes.  (+info)

Characterization of a novel calcium response element in the glucagon gene. (4/3774)

To maintain blood glucose levels within narrow limits, the synthesis and secretion of pancreatic islet hormones is controlled by a variety of extracellular signals. Depolarization-induced calcium influx into islet cells has been shown to stimulate glucagon gene transcription through the transcription factor cAMP response element-binding protein that binds to the glucagon cAMP response element. By transient transfection of glucagon-reporter fusion genes into islet cell lines, this study identified a second calcium response element in the glucagon gene (G2 element, from -165 to -200). Membrane depolarization was found to induce the binding of a nuclear complex with NFATp-like immunoreactivity to the G2 element. Consistent with nuclear translocation, a comigrating complex was found in cytosolic extracts of unstimulated cells, and the induction of nuclear protein binding was blocked by inhibition of calcineurin phosphatase activity by FK506. A mutational analysis of G2 function and nuclear protein binding as well as the effect of FK506 indicate that calcium responsiveness is conferred to the G2 element by NFATp functionally interacting with HNF-3beta binding to a closely associated site. Transcription factors of the NFAT family are known to cooperate with AP-1 proteins in T cells for calcium-dependent activation of cytokine genes. This study shows a novel pairing of NFATp with the cell lineage-specific transcription factor HNF-3beta in islet cells to form a novel calcium response element in the glucagon gene.  (+info)

Identification of domains mediating transcriptional activation and cytoplasmic export in the caudal homeobox protein Cdx-3. (5/3774)

The caudal genes have important functions in embryonic development and cell differentiation. The caudal-related protein Cdx-2/3 (the protein designated Cdx-2 in the mouse and Cdx-3 in the hamster) is expressed in the gastrointestinal epithelium and in islet and enteroendocrine cells, where it activates proglucagon gene transcription. We show here that Cdx-3 sequences amino-terminal to the homeodomain (amino acids 1-180) function as a heterologous transcriptional activation domain when fused to the LexA DNA binding domain. A Cdx-3-Pit-1 fusion protein containing only the first 83 amino acids of Cdx-3 linked to the POU domain of Pit-1 markedly stimulated the transcriptional activity of a Pit-1-responsive promoter. Analysis of the transcriptional properties of Cdx-3 mutants in fibroblasts and islet cells revealed distinct amino-terminal subdomains that function in a cell-specific manner. Point mutations within the amino-terminal A domain were associated with reduced transcriptional activity. Furthermore, internal deletions and selected point mutations within domain A, but not the B or C domains, resulted in accumulation of mutant Cdx-3 in the cytoplasm. Unexpectedly, mutation of an Asp-Lys-Asp motif within domain A identified a putative cytoplasmic membrane-associated export signal that mediates Cdx-3 compartmentalization. These experiments delineate unique activities for specific amino-terminal sequences that are functionally important for Cdx-3 biological activity.  (+info)

Role of glucagon on the control of hepatic protein synthesis and degradation in the rat in vivo. (6/3774)

The effect of glucagon on hepatic protein systhesis and proteolysis has been investigated. The intraperitoneal administration of 200 mug of glucagon produced an increase of the polypeptide chains completion time which was maximal 5 min after its administration and approached control values at 20 min. The increase of the polypeptides chains completion time observed at 5 min after the hormone administration represents a 38% inhibition of the hepatic protein synthetic rate. When glucagon was continuously supplied by intravascular infusion, maximal inhibition was attained throughout the experiment. This inhibition of protein synthesis brought about by glucagon was accompanied by an increase in the polyribosomal state of aggregation, indicating that the hormone acts mainly if not exclusively, on the elongation or termination step, or both. The administration of glucagon produced also a progressive increase in the hepatic valine concentration. This increase could not be accounted for the the decrease in plasma valine levels, suggesting that the rise in haptic valine concentration is an expression of hepatic proteolysis rather than the result of an accelerated transport of amino acids across the hepatocyte plasma membrane. The different time sequence in the glucagon-induced effects of protein synthesis and proteolysis suggests that both effects are independent and probably mediated by different mechanisms.  (+info)

Characterization of beta cells developed in vitro from rat embryonic pancreatic epithelium. (7/3774)

The present study evaluates the development and functional properties of beta cells differentiated in vitro. The authors have previously demonstrated that when E12.5 rat pancreatic rudiments are cultured in vitro in the absence of mesenchyme, the majority of the epithelial cells differentiate into endocrine beta cells. Thus, depletion of the mesenchyme provokes the expansion of endocrine tissue at the expense of exocrine tissue. The potential use of this procedure for the production of beta cells led the authors to characterize the beta cells differentiated in this model and to compare their properties with those of the endocrine cells of the embryonic and adult pancreas. This study shows that the beta cells that differentiate in vitro in the absence of mesenchyme express the homeodomain protein Nkx6.1, a transcription factor that is characteristic of adult mature beta cells. Further, electron microscopy analysis shows that these beta cells are highly granulated, and the ultrastructural analysis of the granules shows that they are characteristic of mature beta cells. The maturity of these granules was confirmed by a double-immunofluorescence study that demonstrated that Rab3A and SNAP-25, two proteins associated with the secretory pathway of insulin, are strongly expressed. Finally, the maturity of the differentiated beta cells in this model was confirmed when the cells responded to stimulation with 16 mM glucose by a 5-fold increase in insulin release. The authors conclude that the beta cells differentiated in vitro from rat embryonic pancreatic rudiments devoid of mesenchyme are mature beta cells.  (+info)

Inactivation of the winged helix transcription factor HNF3alpha affects glucose homeostasis and islet glucagon gene expression in vivo. (8/3774)

Mice homozygous for a null mutation in the winged helix transcription factor HNF3alpha showed severe postnatal growth retardation followed by death between P2 and P12. Homozygous mutant mice were hypoglycemic despite unchanged expression of HNF3 target genes involved in hepatic gluconeogenesis. Whereas insulin and corticosteroid levels were altered as expected, plasma glucagon was reduced markedly in the mutant animals despite the hypoglycemia that should be expected to increase glucagon levels. This correlated with a 70% reduction in pancreatic proglucagon gene expression. We also showed that HNF3alpha could bind to and transactivate the proglucagon gene promoter. These observations invoke a central role for HNF3alpha in the regulatory control of islet genes essential for glucose homeostasis in vivo.  (+info)

The fasting plasma glucagon level was measured in 39 normal subjects, 13 IDDM and 44 NIDDMpatients. The results showed that the glucagon level in both IDDs and NIDDs was significantly higherthan that in normal subjects (P0.001). In addition, 18 normal subjects and 30 NIDDM patientsunderwent a steamed-bread meal test, and the changes in glucagon level was also studied. The glucagonlevel in NIDDM patients was significantly elevated after the meal (P0.05 or less), but in normalsubjects there was no significant change (P0.05). Whereas the glucagon levels before and after themeal in NIDDs were significantly higher than those in normal subjects (P0.05 or less). The rise ofinsulin/glucagon ratio in NIDDs was retarded and much lower that that in normal subjects (P0.01 orless) The results indicate that there exists dysfunction of islet a-cells in diabetic patients, and it maycontribute to hyperglycemia. Insulin/glucagon ratio may be a more perfect index than sole insulin me-asurement in reflecting the

Treatment for significant hypoglycemia will depend on how conscious the patient is.. In some circumstances, someone with diabetes may recover sufficiently to be able to treat the hypo themselves.. Though this may not always be the case and therefore its beneficial to treat severe hypoglycemia as an emergency.. If you know how to apply glucagon via a glucagon injection kit, this is a dependable and effective way to raise blood glucose levels of someone sustaining from a severe hypo. If you apply glucagon, ensure the person is in the recovery state as glucagon can commence to vomiting.. If you do not have access to glucagon, call for emergency hospitalization and have a form of sugar ( fruit juice, a sugary drink, glucose tablets ) available in case they recover.. ...
In the study, intranasal glucagon consistently corrected insulin-induced hypoglycemia in adults with type 1 diabetes, meeting the predefined definition of noninferiority to intramuscular injection of glucagon. In the one case in which intranasal glucagon did not meet the study-defined success criteria, hypoglycemia was corrected without any additional intervention but after the time frame for study-defined success. Average glucose concentrations and time to meet the primary end point after intranasal glucagon lagged ∼3 min behind glucose concentrations after intramuscular glucagon, consistent with the glucagon concentrations showing a relative delay in achievement of peak glucagon levels with intranasal glucagon of ∼5 min. Nevertheless, pharmacologic levels of glucagon were present by 5 min after administration by either approach. The slight delay in glycemic response would likely be clinically inconsequential and in many circumstances might be offset by the time required, errors, and ...
Glucagon secretion by pancreatic α-cells is triggered by hypoglycemia and suppressed by high glucose levels; impaired suppression of glucagon secretion is a hallmark of both type 1 and type 2 diabetes. Here, we show that α-cell glucokinase (Gck) plays a role in the control of glucagon secretion. Using mice with α-cell-specific inactivation of Gck (αGckKO mice), we find that glucokinase is required for the glucose-dependent increase in intracellular ATP/ADP ratio and the closure of KATP channels in α-cells and the suppression of glucagon secretion at euglycemic and hyperglycemic levels. αGckKO mice display hyperglucagonemia in the fed state, which is associated with increased hepatic gluconeogenic gene expression and hepatic glucose output capacity. In adult mice, fed hyperglucagonemia is further increased and glucose intolerance develops. Thus, glucokinase governs an α-cell metabolic pathway that suppresses secretion at or above normoglycemic levels; abnormal suppression of glucagon secretion
Pancreatic expression of the glucagon gene depends on multiple transcription factors interacting with at least three DNA control elements: G1, the upstream promoter element, and G2 and G3, two enhancer-like sequences. We report here that the major enhancer of the rat glucagon gene, G2, interacts with three protein complexes, A1, A2, and A3. A2 is detected only in islet cells, and impairment of its binding to mutant G2 causes a marked decrease in transcriptional activity. We identify A1 as hepatocyte nuclear factor 3 beta (HNF-3 beta), a member of the HNF-3 DNA-binding protein family found in abundance in the liver which has been proposed to play a role in the formation of gut-related organs. HNF-3 beta binds G2 on a site which overlaps A2 and acts as a repressor of glucagon gene expression, as demonstrated by mutational analyses of G2 and by cotransfection of HNF-3 beta cDNA along with reporter genes containing G2 into glucagon-producing cells. Our data implicate HNF-3 beta in the control of ...
Hyperglucagonemia is an important factor for type 2 diabetes which contributes to increased hepatic glucose production (Rizza 2010). In spite of this, however, little is known about the role of chronically elevated glucagon levels for β-cell function. A reason for this is the lack of appropriate models of long-term glucagon action, which in part is due to difficulties in administering native glucagon long-term because of poor chemical and physical stability. Therefore, in the current study, we administered a stable glucagon analog (ZP-GA-1) to mice fed a HFD to create a novel model for studying effects of chronic GCGR activation on β-cell function. The HFD fed mice do not develop hyperglucagonemia (Ahlkvist et al. 2013) which allowed us to study the impact of chronic GCGR stimulation on glucose tolerance in a glucose intolerant model without the confounding factor of endogenous hyperglucagonemia. In these mice, 2-week ZP-GA-1 infusion markedly reduced the insulin response to oral glucose. ...
Anti-glucagon antibodies have shown some efficacy in animal models (Brand et al., 1994, 1996; Sørensen et al., 2006a); however, daily injections of high doses of antibodies were required (Sørensen et al., 2006). The lack of long-term efficacy of the antibody on blood glucose lowering is probably due to a compensatory mechanism involving oversecretion of endogenous glucagon in response to the reduction of glucagon receptor signaling. Increases in circulating glucagon levels have been reported with all modalities blocking the glucagon signaling pathway, which presents technical challenges for both small-molecule GCGR inhibitors and glucagon-neutralizing mAb approaches.. Despite rising glucagon levels, treatment with neutralizing hGCGR mAbs maintained glucose-lowering efficacy. These anti-GCGR mAbs have several desirable attributes as potential therapeutic agents compared with previously pursued approaches. First, mAb B showed a higher affinity than glucagon to the GCGR (Kd = 36 pM versus Kd = ...

Intracerebroventricular administration of glucagon in chicks induced hyperglycemia and anorexia from 30. min after administration. However, the plasma insulin level did not increase until 90. min after glucagon administration, suggesting that glucose-stimulated insulin secretion from pancreatic beta cells may be suppressed by central glucagon. The plasma corticosterone concentration significantly increased from 30. min to 120. min after administration, suggesting that central glucagon activates the ...
Toxicology Question of the Week. June 13, 2017. How does glucagon ameliorate the hypotension caused by beta-blocker toxicity?. Glucagon is a hormone secreted from pancreatic alpha cells. It has inotropic and chronotropic cardiac effects. When the beta receptor is stimulated, cAMP is increased and calcium influx (via L-type calcium channels) also increases. When the beta receptor is blocked, glucagon stimulates the same subcellular protein to increase cAMP production and increase calcium influx.. Glucagon administration is indicated for hypotension, bradycardia or conduction impairment. It may also be effective in treating hypotension in calcium channel blocker and other overdoses with cardiac toxicity.. IF dose is too high or pushed IV too fast, the patient will vomit. A bolus of 5-10 mg (150 mcg/kg) given over 10 minutes is less likely to have this side effect. Glucagons half-life is 6 minutes so a continuous infusion of 3 mg/hr (50-100 mcg/kg/hr) should follow this bolus.. References:. DeWitt ...
Glucagon is a hormone that causes increase in blood glucose by promoting breakdown of liver glycogen. Glucagon is used for emergency treatment of severe hypoglycaemia. Administration of therapeutic glucagon as a rescue treatment for severe hypoglycaemia is safe and effective, however, its use is challenging due to its low solubility and very poor stability in liquid solution. Thus, currently available glucagon treatments (rescue kits) are only available in the form of a lyophilised powder, which requires the caregiver to perform a complex multi-step reconstitution procedure prior to administration in this highly stressful emergency situation. The reconstitution procedure leads to handling errors and delayed administration of glucagon, resulting in sub-optimal treatment. This is a significant barrier to the use of these rescue kits with recent usability studies demonstrating that more than 80% of people failed to reconstitute properly and inject the recommended dose of glucagon. As a result, only ...
Previous studies have shown that the α cell is critical for a normal counterregulatory response to insulin-induced hypoglycemia (4, 6-9). In fact, glucagon is widely thought to provide the primary defense against a low blood glucose level. On the other hand, insulin is known to exert a powerful restraining effect on glucagons action (3). This raises the question of how glucagon can have such a prominent role in counterregulation if it is so easily subject to insulins inhibitory action. The aim of the present study, therefore, was to determine the extent to which hypoglycemia enhances glucagons ability to overcome insulins inhibitory action on the liver and to shed light on the mechanism by which this occurs. The present results indicate that hypoglycemia (~50 mg/dl), or some factor associated with it, enhanced glucagons ability to increase glucose production almost 3-fold, even in the presence of extremely high insulin levels. Furthermore, they showed that this change reflected a marked ...
Serum insulin response to intravenous administration of 1 mg. glucagon and 25 or 40 gm. glucose plus 1 mg. glucagon has been studied in normal and markedly obese nondiabetic patients and compared to the responses of infusions of glucose alone.. In both groups, serum immunoreactive insulin (IRI) rose to a maximal level within five minutes after the end of each injection, but the rise was significantly higher in the obese subjects. In spite of the augmented rise of IRI after a glucose plus glucagon infusion, the mean rate of glucose disappearance did not change significantly in the obese subjects, a finding which suggested impaired sensitivity to endogenous insulin. In obese subjects, who are known to have hyperplasia of the islets of Langerhans, the enhancement of insulin secretion by glucagon appears greater.. ...
The dynamics and interrelationships of glucagon and insulin secretion were studied in the isolated perfused rat pancreas by utilizing a series of compounds that stimulate the release of both hormone. Leucine, arginine, prostaglandins F2α and E2, bovine growth hormone, and isoproterenol were administered individually over 60-second intervals. The release of glucagon preceded that of insulin in response to all compounds tested. The rapidity of glucagon release varied in response to different secretagogues; the time course of insulin release was fairly constant. The timing and the magnitude of glucagon and insulin release did not correlate statistically. Conclusions: (1) pancreatic alpha cells respond more rapidly than beta cells to the same stimulus; (2) antecedent release of glucagon is not the principal mediator of insulin release in response to stimuli common to both hormones; and (3) endogenous glucagon may at best modify the release of insulin evoked by certain secretagogues.. ...
Hyperglucagonemia is a state of excess glucagon secretion. In healthy individuals, insulin has a suppressive effect on alpha-cell function and on glucagon secretion.
Glucagon rescue is the emergency injection of glucagon in case of severe diabetic hypoglycemia. It is needed during seizures and/or unconsciousness by an insulin user who is unable at that point to help themselves. Glucagon will facilitate the release of stored glucose back into the bloodstream, raising the blood glucose level. Rescue has been simplified by the development of the glucagon hypoglycemia rescue kit, consisting of: biosynthetic human glucagon, in a freeze dried form within a vial, a sturdy syringe, pre-filled with a sterile diluting solution, and a conspicuous red or orange colored plastic storage box, which includes instructions. At the first signs of hypoglycemia, an insulin user should treat it immediately by consuming carbohydrate to restore blood glucose to safe levels (thereby preventing progression to severe hypoglycemia). However, not all insulin users can feel and recognize the early signs, particularly when sleeping. This can quickly lead to an emergency resulting in ...

The aim of this study was to investigate the role of plasma glucagon levels on the blood glucose response to intravenous insulin administered continuously or in a pulsatile manner. Six type I diabetic patients proven to have no residual insulin secretion were investigated. Endogenous glucagon secretion was inhibited by a continuous intravenous infusion of somatostatin (100 micrograms/h) and replaced by exogenous infusions of the hormone at three different rates (7.5, 4.5, and 2.5 micrograms/h), resulting in three different plasma glucagon steady-state levels (i.e., approximately equal to 200, approximately equal to 130, and approximately equal to 75 pg/ml, respectively). Each subject, in random order and on different days, was infused intravenously ...
The human body wants blood glucose (blood sugar) maintained in a very narrow range. Insulin and glucagon are the hormones which make this happen. Both insulin and glucagon are secreted from the pancreas, and thus are referred to as pancreatic endocrine hormones. The picture on the left shows the intimate relationship both insulin and glucagon have to each other. Note that the pancreas serves as the central player in this scheme. It is the production of insulin and glucagon by the pancreas which ultimately determines if a patient has diabetes, hypoglycemia, or some other sugar problem. Insulin and glucagon are hormones secreted by islet cells within the pancreas (more about islet cells of the pancreas). They are both secreted in response to blood sugar levels, but in opposite fashion! Insulin is normally secreted by the beta cells (a type of islet cells) of the pancreas. The stimulus for insulin secretion is a HIGH blood glucose...its as simple as that! Although there is always a low level of ...
Glucagon is conventionally regarded as a counterregulatory hormone for insulin and plays a critical anti-hypoglycemic role by maintaining glucose homeostasis in both animals and humans. To increase blood glucose, glucagon promotes hepatic glucose output by increasing glycogenolysis and gluconeogenesis and by decreasing glycogenesis and glycolysis in a concerted fashion via multiple mechanisms. Glucagon also stimulates hepatic mitochondrial beta-oxidation to supply energy for glucose production. Glucagon performs its main effect via activation of adenylate cyclase. The adenylate-cyclase-derived cAMP activates protein kinase A (PKA), which then phosphorylates downstream targets, such as cAMP response element binding protein (CREB) and the bifunctional enzyme 6-phosphofructo-2-kinase/ fructose-2,6-bisphosphatase (one of the isoforms being PFK/FBPase 1, encoded by PFKFB1 ...

At the turn of the century, Holst, working with scientists from Novo Nordisk, reported that glucagon suppression in mice resulted in massive enlargement of the pancreas and the proliferation of α cells (α cell hyperplasia).25 They concluded that α cells appear not just in the islets but in the pancreatic ductal epithelium-something that Butler and colleagues found. Importantly, this effect did not require complete blocking of glucagon receptors or the stopping of glucagon production. Even a partial reduction in the hormone signalling resulted in α cell hyperplasia, as shown by Eli Lilly in 2004.26 The Lilly team acknowledged that they hadnt seen any neoplasia; the studies up until that point had been short-only four months long. They suggested that both glucagon and its receptor must be functional in order to maintain a feedback loop that restrains α cell growth but the exact nature of this feedback loop is unclear.26 ...
As explained in this part of the eMedTV site, if you have a tendency to develop low blood sugar, your healthcare provider will likely recommend having a glucagon injection kit in case of an emergency. This article gives a brief overview of this product.
Intranasal glucagon can raise blood glucose levels in healthy subjects. The aims of this study were to 7) compare the hyperglycemic effect of intranasal and intramuscular glucagon in healthy subjects and type I (insulin-dependent) diabetes patients during euglycemic conditions and 2) test the efficacy of intranasal and intramuscular glucagon in counteracting hypoglycemic episodes in insulin-treated diabetic patients. Intranasal glucagon raised blood glucose levels in both healthy subjects and type I diabetic patients, the effect of intramuscular glucagon being similar for the first 30 min and higher thereafter. Intranasal glucagon was also quicker acting than oral glucose in healthy subjects. Intranasal glucagon raised blood glucose levels in patients with hypoglycemic episodes, although less effectively than intramuscular glucagon. These data indicate intranasal glucagon as a possible emergency remedy for self-medication in insulin-treated patients prone to hypoglycemic episodes.. ...

Plasma glucagon, insulin and glucose concentrations, and liver function tests were determined after an overnight fast in 24 normal subjects and 50 male cirrhotic patients. In cirrhotic patients with normal liver profiles, plasma glucagon remained within normal limits, irrespective of the presence of portasystemic anastomoses either pathological or surgical. Hyperglucagonemia was documented in presence of advanced liver dysfunction alone. Significant correlations were established between plasma glucagon and several liver function tests, i.e., serum bilirubin, albumin/globulin ratio, and prothrombin time. Moreover, hyperglucagonemia normalized on recovery from clinical manifestations and improvement in liver profile. Plasma insulin was raised primarily in the presence of a significant portasystemic shunting and maximum levels were observed in patients manifesting advanced liver dysfunction as well. However, no correlation was evident between plasma insulin and any of the liver function tests. Fasting
Glucagon is an essential pancreatic hormone that raises the blood sugar level. Glucagon administration is sometimes required to treat hypoglycemia in diabetes.
Ok - moving on now that any newbies know what a glucagon kit is and why it is used.. I anticipated the office staff (there is no nurse on school property other than on Fridays) having an idea of what a glucagon kit is and who should be contacted if it is required.. I got blank stares. The two office staffers knew nothing about glucagon. Not only had they never seen one they didnt believe any staff on campus knew what they were or if any were trained to use the emergency kit.. Seriously? My son is not the only cwd at the school. There are at least 3 others that I know of, maybe more. Certainly someone in the school knows about diabetes and glucagon and emergency diabetes care.. A bit of back story. California as a whole sucks big time at diabetes in school. There are some schools and some districts that are better than others at providing support. But up until July of 2013 no non-licensed person (meaning no one that wasnt a certified nurse) could assist in insulin injections. In July the CA ...

Glucagon plays a major role in the regulation of glucose homeostasis during fed and fasting states. However, the mechanisms responsible for the regulation of pancreatic α cell mass and function are not completely understood. In the current study, we identified mTOR complex 1 (mTORC1) as a major regulator of α cell mass and glucagon secretion. Using mice with tissue-specific deletion of the mTORC1 regulator Raptor in α cells (αRaptorKO), we showed that mTORC1 signaling is dispensable for α cell development, but essential for α cell maturation during the transition from a milk-based diet to a chow-based diet after weaning. Moreover, inhibition of mTORC1 signaling in αRaptorKO mice and in WT animals exposed to chronic rapamycin administration decreased glucagon content and glucagon secretion. In αRaptorKO mice, impaired glucagon secretion occurred in response to different secretagogues and was mediated by alterations in KATP channel subunit expression and activity. Additionally, our data ...

A scourge of Type I and Type II diabetes impacts the health of hundreds of millions worldwide. The number and prevalence of diabetics are expected to rise dramatically in the next two decades. Diabetes is defined by chronic hyperglycemia which can result in a number of detrimental and costly metabolic, renal, cardiovascular and neurological disorders. Identification of at risk individuals and effective blood glucose management are critical to improving diabetic outcomes and preventing hyperglycemic complications. Diabetes prevention and treatment is limited by the understanding of islet function and mass in the diabetogenic and diabetic state. The islets of Langerhans are dispersed throughout the pancreas and comprise ,2% of the pancreatic mass. The reclusive nature of islet cells presents unique challenges understanding disease development. No agent capable of exclusively targeting pancreatic β-cells within the islet has been discovered and the lack of targeting agent specificity impedes ...

Glucagon: A 29-amino acid pancreatic peptide derived from proglucagon which is also the precursor of intestinal GLUCAGON-LIKE PEPTIDES. Glucagon is secreted by PANCREATIC ALPHA CELLS and plays an important role in regulation of BLOOD GLUCOSE concentration, ketone metabolism, and several other biochemical and physiological processes.

Glucose production is inappropriately increased in people with type 2 diabetes both before and after food ingestion. Excessive postprandial glucose production occurs in the presence of decreased and delayed insulin secretion and lack of suppression of glucagon release. These abnormalities in hormone secretion, coupled with impaired insulin-induced suppression of glucose production and stimulation of splanchnic glucose uptake, likely account in large part for the excessive amounts of glucose that reach the systemic circulation for disposal by peripheral tissues following food ingestion. In contrast, when adequate basal insulin concentrations are present, neither glucagon-induced stimulation of glucose production nor glucose-induced suppression of glucose production differs in diabetic and nondiabetic subjects matched for gender, age, and degree of obesity. However, when insulin secretion is defective, lack of suppression of glucagon can cause substantial hyperglycemia by enhancing rates of ...
Patients with type 2 diabetes (T2D) and patients with non-alcoholic fatty liver disease (NAFLD) frequently exhibit elevated plasma concentrations of glucagon (hyperglucagonemia). Hyperglucagonemia and alpha-cell hyperplasia may result from elevated levels of plasma amino acids when glucagons action on hepatic amino acid metabolism is disrupted. We therefore measured plasma levels of glucagon and individual amino acids in patients with and without biopsy-verified NAFLD and with and without type T2D. Fasting levels of amino acids and glucagon in plasma were measured, using validated ELISAs and high-performance liquid chromatography, in obese, middle-aged individuals with I) normal glucose tolerance (NGT) and NAFLD, II) T2D and NAFLD, III) T2D without liver disease, and IV) NGT and no liver disease ...
Dear Dr. G,. how are you? First, as always I am thankful for all your effort to respond to the messages to all of us on this board. I am interested in your take on insulin vs glucagon. What do you say to this:. Insulin is created when we intake sugars and glucagon is created when we intake fats. Insulin is a fat storing hormone and glucagon is a fat burning hormone. So, you have to eat fats to burn fats.. My thoughts:. - If this was true, people who eat high fat diets would be generally more slim and people who eat high fruit diets would be generally fat. - The author apparently doesnt mention fruit, but sugar.. - One can get fat or slim on ANY diet. Yes, I am sure of this, because I see people in good outside physical shape on many different diets and in bad outside and apparently inside shape on also many different diets. ...

Glucagon is released in a single day and between meals and is critical in keeping the bodys sugar and gas balance. It signals the liver to break down its starch or glycogen stores and enables to shape new glucose gadgets and ketone devices from different substances. It also promotes the breakdown of fat in fat cells.. Glucagon is secreted by means of the alpha cells of the pancreatic islets in a whole lot the same way as insulin…except within the opposite path. If blood glucose is high, then no glucagon is secreted. while blood glucose goes LOW, however, (such as between meals, and all through exercising) increasingly more glucagon is secreted. Like insulin, glucagon has an effect on many cells of the frame, however most considerably the liver.. The impact of glucagon is to make the liver release the glucose it has saved in its cells into the bloodstream, with the internet effect of growing blood glucose. Glucagon also induces the liver (and some different cells such as muscle) to make ...

Abstract: In addition to its primary role in regulating glucose production from the liver, glucagon has many other actions, reflected by the wide tissue distribution of the glucagon receptor (Gcgr). To investigate the role of glucagon in the regulation of insulin secretion and whole body glucose homeostasis in vivo, we generated mice overexpressing the Gcgr specifically on pancreatic β-cells (RIP-Gcgr). In vivo and in vitro insulin secretion in response to glucagon and glucose was increased 1.7- to 3.9-fold in RIP-Gcgr mice compared with controls. Consistent with the observed increase in insulin release in response to glucagon and glucose, the glucose excursion resulting from both a glucagon challenge and intraperitoneal glucose tolerance test (IPGTT) was significantly reduced in RIP-Gcgr mice compared with controls. However, RIP-Gcgr mice display similar glucose responses to an insulin challenge. β-Cell mass and pancreatic insulin content were also increased (20 and 50%, respectively) in ...
BioAssay record AID 293012 submitted by ChEMBL: Displacement of [125]glucagon from human glucagon receptor expressed in CHO cells.
Assays for the pancreatic hormone glucagon have typically been carried out using RIAs, but specificity has always been a problem, as the same amino acid sequence is present in other endogenous peptides in addition to glucagon, as discussed in the Introduction. Sensitivity (i.e. the smallest concentration of a substance that can be reliably measured) is also a prominent issue, as circulating concentrations are likely to be low, around 10 pmol/l or less (22). The relevant changes in glucagon secretion, resulting from changes in plasma glucose concentrations, are also modest with increases in response to hypoglycaemia ranging from 20 to 30 pmol/l, but even more challenging are decreases in response to hyperglycaemia, which may lower the concentrations to 1-2 pmol/l (24). Clearly, assays with sensitivities ,5 pmol/l are, therefore, unsuitable for the complete characterisation of glucagon secretion. The present study demonstrates that it is important to test a commercial assay carefully before being ...

AU - Londos, C.. AU - Rendell, M.. AU - Rodbell, M.. PY - 1975/12/1. Y1 - 1975/12/1.

This study shows that only guanine nucleotides containing triphosphate groups at the 5 position of ribose (or 3 deoxyribose) are capable of activating the enzyme. The terminal phosphate is not utilized in the activation process, since 5 guanylylimidodiphosphate [Gpp(NH)p] and 5 guanylyl methylenediphosphonate, analogues of guanosine triphosphate that are not utilized in transferase or hydrolase reactions, stimulate enzyme activity. The nucleotides bind in their free form at the regulatory site; chelation by magnesium ...
OBJECTIVE-Leptin released from adipocytes plays a key role in the control of food intake, energy balance, and glucose homeostasis. In addition to its central action, leptin directly affects pancreatic beta-cells, inhibiting insulin secretion, and, thus, modulating glucose homeostasis. However, despite the importance of glucagon secretion in glucose homeostasis, the role of leptin in a-cell function has not been studied in detail. In the present study, we have investigated this functional interaction. RESEARCH DESIGN AND METHODS-The presence of leptin receptors (ObR) was demonstrated by RT-PCR analysis, Western blot, and immunocytochemistry. Electrical activity was analyzed by patch-clamp and Ca(2+) signals by confocal microscopy. Exocytosis and glucagon secretion were assessed using fluorescence methods and radioimmunoassay, respectively. RESULTS-The expression of several ObR isoforms (a-e) was detected in glucagon-secreting alpha TC1-9 cells. ObRb, the main isoform involved in leptin signaling, ...
Description: A modestly active, nonselective triarylimidazole lead was optimized for binding affinity with the human glucagon receptor.

The effect of glucagon on the rate of muscle protein synthesis was examined in vivo and in the isolated perfused rat hemicorpus. An inhibition of protein synthesis in skeletal muscles from overnight-fasted rats at various plasma concentrations of glucagon was demonstrated in vivo. The plantaris muscle (Type II, fibre-rich) was more sensitive than the soleus (Type I, fibre-rich). Myofibrillar and sarcoplasmic proteins were equally sensitive in vivo. However, protein synthesis in mixed protein and in sarcoplasmic and myofibrillar fractions of the heart was unresponsive to glucagon in vivo. In isolated perfused muscle preparations from fed animals, the addition of glucagon also decreased the synthesis of mixed muscle proteins in gastrocnemius (Type I and II fibres) and plantaris, but not in the soleus. The sarcoplasmic and myofibrillar fractions of the plantaris were also equally affected in vitro. Similar results were observed in vitro with 1-day-starved rats, but the changes were less marked. ...
We have monitored electrical activity, voltage-gated Ca2+ currents, and exocytosis in single rat glucagon-secreting pancreatic A-cells. The A-cells were electrically excitable and generated spontaneous Na+- and Ca2+-dependent action potentials. Under basal conditions, exocytosis was tightly linked to Ca2+ influx through omega-conotoxin-GVIA-sensitive (N-type) Ca2+ channels. Stimulation of the A-cells with adrenaline (via beta-adrenergic receptors) or forskolin produced a greater than fourfold PKA-dependent potentiation of depolarization-evoked exocytosis. This enhancement of exocytosis was due to a 50% enhancement of Ca2+ influx through L-type Ca2+ channels, an effect that accounted for |30% of the total stimulatory action. The remaining 70% of the stimulation was attributable to an acceleration of granule mobilization resulting in a fivefold increase in the number of readily releasable granules near the L-type Ca2+ channels.

Hypothesis:. Pegvisomant combined with the glucagon stimulation test (GST) can improve the accuracy of this test when used to diagnose adult GH and cortisol (steroid hormone)insufficiency.. Study aims:. Diagnosing GH and cortisol deficiency in adults requires a special test. At present, the insulin tolerance test (ITT) is considered the test of choice. However, this test is difficult to perform as it involves giving insulin through the veins to decrease blood sugars to very low levels, and this can be unpleasant, and cannot be performed in elderly adults and in those with a history of heart disease, seizure disorders or stroke. For this reason there is an urgent need for an alternative reliable test. At present, the GST is considered the alternative test to the ITT but its accuracy in obese patients and in those with diabetes remains unclear. Pegvisomant is a medication that can increase GH production in the body. The purpose of this study is to find out if combining pegvisomant with the GST can ...
We have studied the effect of glucagon on the expression of a triiodothyronine (T3) and carbohydrate-inducible mRNA sequence (mRNA-S14) in rat liver that undergoes a threefold diurnal variation (peak, 2200 h; nadir, 0800 h). Glucagon injection into euthyroid rats (25 micrograms/100 g body wt i.p., three doses at 15-min intervals) during the nocturnal plateau of mRNA-S14 caused a monoexponential disappearance of this sequence (t1/2, 90 min) accompanied by a 90% reduction in the transcriptional rate in a nuclear run-off assay, indicative of a near total reduction of synthesis. This effect was markedly attenuated in rats treated with T3 (200 micrograms/100 g body wt i.p.) 24 h before glucagon injection. When T3 was given 15 min after glucagon, the glucagon-initiated decline in mRNA-S14 was reversed within 90 min, suggesting a rapid interaction between the two hormones in the evening. Curiously, administration of T3 alone at this hour did not affect a significant increase in mRNA-S14. At 0800 h, ...

I doubt they ever will. From what I understand, glucagon doesnt have a very long half-life once mixed. Thats why you have to mix it at the time you need it. It really would be nice if they could make it premixed though! We use normal insulin syringes and inject it SQ, not IM (it can be done either way). Its a lot less intimidating that way. :) We keep an insulin syringe and a tube of glucose gel taped to the top of the glucagon kit, per drs suggestion.

Glucagon acts on hepatocytes (liver cells) to: convert glycogen into glucose (glycogenolysis) form glucose from lactic acid and certain amino acids (gluconeogenesis) Low blood glucose (hypoglycemia) stimulates alpha cells to secrete GLUCAGON 1 2
Glucagon that can be administered via the nose is being developed, and may help alleviate anxiety about severe hypoglycemia (low blood sugar) for those with type 1 diabetes. Nasal glucagon powder does not have to be consciously inhaled - it is absorbed passively in the nasal passage - so can easily be given to awake or unconscious individuals.
B A Hansen,. We studied the effect of fructose on hepatic conversion of amino-N to urea-N as quantified by the Capacity of Urea-N Synthesis (CUNS) determined in rats during alanine loading. There were 2 control groups, one without and one with infusion of somatostatin, in order to control the effects of insulin and glucagon. Somatostatin reduced CUNS from 8.5 +/- 0.5 mumol/(min x 100 g BW) to 6.3 +/- 0.3 mumol/(min x 100 g BW) (mean +/- SEM) (p , 0.01) and reduced glucagon concentrations by 75% (p,0.05). Insulin and glucose concentrations did not change. Fructose, at blood concentrations of about 1 mmol/l further reduced CUNS to 3.6 +/- 0.3 mumol/(min x 100 g BW) (p , 0.01). Insulin increased slightly (p , 0.05), but neither glucose nor glucagon changed. At increasing fructose concentrations up to 2 mmol/l there was no further effect on CUNS. Fructose in concentrations as used for parenteral nutrition and independent of glucoregulatory hormones, decreased hepatic amino acid catabolism. ...
Keep glucagon on hand. If you become unconscious when your blood sugar is very low, someone may need to give you a shot of glucagon to raise your blood sugar. Be sure someone knows how to give you the shot. Have the person practice by giving you your insulin shot once or twice a month. This will help the person be confident if he or she has to give you a shot of glucagon in an emergency. Keep the instructions for how to give glucagon with the medicine. Also, check the expiration date on your glucagon. Most kits need to be replaced every 6 months ...

Pump size exterior artificial pancreas that will keep the glucose between 120 - 150mg/dl. The whole project based on the idea that we should already know one insulin unit how much is able to go down the glucose and one glucagons unit how much is able to increase the glucose. Less than 120 mg/dl it uses glucagons. More than 150 mg/dl it uses insulin. The pump checks the glucose automatically for every 8 minutes. The pump (which is software decision) will choose between insulin or glucagons base in an internal database table with prerequisite glucose values and the insulin or glucagons units requiring for each glucose value (adaptive database table for each diabetic). The pump (the software) is able to choose how many insulin or glucagon units it should use (that is not based on what the diabetic will eat, but base on the current glucose level that received from the sensor which is located in the human body, needle and sensor are one piece). The insulin should have a work duration of 8 minutes and works
The relationships between first-phase insulin secretion to i.v. glucagon and i.v. arginine were studied in 19 healthy adult volunteers (Group I) and in 21 subjects at risk for Type 1 (insulin-dependent) diabetes mellitus with either a normal (n = 11; Group IIa) or a low insulin response to i.v. …
Endocrine cell clusters (aka pancreatic islets or islets of Langerhans) secrete insulin and glucagon. Insulin and glucagon regulate blood glucose levels. After a meal, when blood glucose levels rise, insulin is released so that cells can uptake the elevated glucose levels. Liver and skeletal muscles form glycogen, a carbohydrate.. As glucose levels fall, insulin production is inhibited. Glucagon causes breakdown of glycogen into glycose, which is in turn released into the blood to maintain homeostatic glucose levels. Glucagon production is stimulated by low blood glucose levels, and inhibited when they rise. ...
Somatostatin, a hypothalamic peptide that inhibits the secretion of pituitary growth hormone, inhibits basal insulin secretion in fasted cats and rats. In fasted baboons both basal and arginine-stimulated secretion of insulin and glucagon are inhibited. Somatostatin appears to act directly on the endocrine pancreas. The action is dose-related, rapid in onset, and readily reversed. ...

Intercellular communication is pivotal in optimising and synchronising cellular responses to keep internal homeostasis and to respond adequately to external stimuli. In the central nervous system (CNS), glutamatergic and GABAergic signals are postulated to be dependent on the glutamate/GABA-glutamine (GGG) cycle for vesicular loading of neurotransmitters, for inactivating the signal and for the replenishment of the neurotransmitters. Islets of Langerhans release the hormones insulin and glucagon, but share similarities with CNS cells in for example transcriptional control of development and differentiation, and chromatin methylation. Interestingly, proteins involved in the CNS in secretion of the neurotransmitters and emitting their responses as well as the regulation of these processes, are also found in islet cells. Moreover, high levels of glutamate, GABA and glutamine and their respective vesicular and plasma membrane transporters have been shown in the islet cells and there is emerging support for

Spherical clusters of cells throughout the pancreas, called the islets of Langerhans, produce and secrete the peptide hormones insulin (produced by beta cells) and glucagon (produced by alpha cells), which regulate blood glucose levels, as well as the hormone somatostatin, which inhibits the secretion of both insulin and glucagon. Insulin lowers blood glucose (lowers cAMP levels in signal transduction), speeding the conversion of glucose into glycogen (as well as the conversion of amino acids into protein). To raise glucose levels, alpha cells secrete glucagon, which brings about glycogenolysis (cAMP is raised in target cells). Somatostatin is secreted by delta cells ...
Reflecting the increasingly common analogies between computer science and biology in the 1960s, Rodbell believed that the fundamental information processing systems of both computers and biological organisms were similar. He asserted that individual cells were analogous to cybernetic systems made up of three distinct molecular components: discriminators, transducers, and amplifiers (otherwise known as effectors). The discriminator, or cell receptor, receives information from outside the cell; a cell transducer processes this information across the cell membrane; and the amplifier intensifies these signals to initiate reactions within the cell or to transmit information to other cells.. In December 1969 and early January 1970, Rodbell was working with a laboratory team that studied the effect of the hormone glucagon on a rat liver membrane receptor-the cellular discriminator that receives outside signals. Rodbell discovered that ATP (adenosine triphosphate) could reverse the binding action of ...
One way to arrive at the correct answer is to recall that the actions of epinephrine resemble that of glucagon in opposing insulin. However, since epinephrine is a catecholamine, its receptor must be distinct from the glucagon receptor, which binds a polypeptide ligand. Otherwise, the similarity with glucagon holds, in that both agents exert their effects on the liver (or muscle) cell by raising cAMP to activate protein kinase A. For the purposes of the Biochemistry course (but not necessarily Physiology!), do not worry about the distinction between beta-1 and beta-2. But there is more to the epinephrine story... ...
