26 9421373 After GLP-1 infusion, there was an abrupt increase in the peripheral concentrations of serum C-peptide (696 +/- 65 vs. 1,538 +/- 165 pmol/l) and insulin (49 +/- 8 vs. 138 +/- 21 pmol/l) concentrations.
27 9421373 This increase was mainly due to an increase in the pulsatile component of insulin secretion that was achieved by a fourfold increase in secretory burst mass (28.2 +/- 4.4 vs. 100.1 +/- 15.8 pmol x l-1 x pulse-1; P < 0.001), and amplitude (12.7 +/- 2.2 vs. 4.3 +/- 7.7 pmol x l-1 x min-1; P < 0.002), whereas the secretory burst frequency was not affected by GLP-1 (11.5 +/- 0.7 vs. 12.6 +/- 0.6 pulses/h; P = 0.4).

55 15140754 Glucagon-like peptide 1 (GLP-1) is an intestine-derived insulinotropic hormone that stimulates glucose-dependent insulin production and secretion from pancreatic beta-cells.
56 15140755 These effects, in addition to the stimulation of insulin secretion, suggest a broad role for GLP-1 as a mediator of postprandial glucose homeostasis.
57 15140755 Whereas other insulinotropic gastrointestinal hormones are relatively ineffective in stimulating insulin secretion in persons with type 2 diabetes, GLP-1 retains this action and is very effective in lowering blood glucose levels in these patients.
58 15143860 Agonists of glucagon-like-peptide 1 (GLP-1) and antagonists of dipeptidylpeptidase IV, which inactivates GLP-1, stimulate glucose-dependent insulin secretion, improve hyperglycemia and are already tested in clinical trials.
59 15155141 Glucagon-like peptide-1 (GLP-1) is a peptide hormone from the gut that stimulates insulin secretion and protects beta-cells, inhibits glucagon secretion and gastric emptying, and reduces appetite and food intake.
60 15039452 In an oral glucose tolerance test on day 1, the coadministration caused a greater improvement of glucose tolerance and a prominent increase of plasma active GLP-1 without marked insulin secretion.
61 15803906 GLP-1 controls blood glucose following nutrient absorption via stimulation of glucose-dependent insulin secretion, insulin biosynthesis, islet proliferation, and neogenesis and inhibition of glucagon secretion.
62 16215105 Intriguingly, GLP-1 hormones may have important biologic actions aside from stimulating insulin release, including inhibition of gastric motility and acid secretion, suppression of glucagon secretion, and islet cell proliferation.
63 15604213 In this study, we explored whether DPP-4 inhibition by valine-pyrrolidide (val-pyr; 100 micromol/kg administered through gastric gavage at t = -30 min) affects the insulin and glucose responses to iv glucose (1 g/kg) together with GLP-1 (10 nmol/kg), glucose-dependent insulinotropic polypeptide (GIP; 10 nmol/kg), pituitary adenylate cyclase-activating polypeptide 38 (PACAP38; 1.3 nmol/kg), or gastrin-releasing peptide (GRP; 20 nmol/kg) given at t = 0 in anesthetized C57BL/6J mice.
64 15604213 The augmented insulin response to GRP by val-pyr was prevented by the GLP-1 receptor antagonist, exendin(3) (9-39), raising the possibility that GRP effects may occur secondary to stimulation of GLP-1 secretion.
65 15604213 We conclude that DPP-4 inhibition augments the insulin response not only to GLP-1 but also to GIP, PACAP38, and GRP.
66 15769092 The in vitro insulinotropic effect of PEG(2k)-Lys-GLP-1 showed comparable biological activity with native GLP-1 (P = 0.11) in stimulating insulin secretion in isolated rat pancreatic islet and was significantly more potent than the PEG(2k)-N(ter)-GLP-1 (P < 0.05) that showed a marked reduced potency.
67 15780433 The actions of GLP-1 include (a) a stimulation of insulin secretion in a glucose-dependent manner, (b) a suppression of glucagon, (c) a reduction in appetite and food intake, (d) a deceleration of gastric emptying, (e) a stimulation of beta-cell neogenesis, growth and differentiation in animal and tissue culture experiments, and (f) an in vitro inhibition of beta-cell apoptosis induced by different toxins.
68 15770466 Their development is based on the observation that DPP-IV rapidly inactivates the incretin hormone glucagon-like peptide-1 (GLP-1), which is released postprandially from the gut and increases insulin secretion.
69 15842525 Glucagon-like peptide-1 (GLP-1) and gastric inhibitory polypeptide (GIP) are important insulinotropic hormones that enhance the insulin secretory response to feeding.
70 15852457 The multifaceted actions of GLP-1 include the following: (1) the stimulation of insulin secretion and of its gene expression, (2) the inhibition of glucagon secretion, (3) the inhibition of food intake, (4) the proliferation and differentiation of beta cells, and (5) the protection of beta-cells from apoptosis.
71 15983224 Glucagon-like peptide 1 (GLP-1) has been proposed to act as an incretin hormone due to its ability to enhance glucose-stimulated insulin secretion.
72 15983224 Because GLP-1 also decelerates gastric emptying, it physiologically reduces rather than augments postprandial insulin secretory responses.
73 15983224 Therefore, we aimed to antagonize the deceleration of gastric emptying by GLP-1 to study its effects on insulin secretion after a meal.
74 15983224 Despite augmented rises in insulin secretion, the glucose-lowering effect of GLP-1 is markedly reduced when the deceleration of gastric emptying is antagonized, illustrating the importance of this facet of the multiple antidiabetic actions of GLP-1.
75 15886226 The latter is also dependent on stimulation of insulin secretion by glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1).
76 15978877 It was published in 1996 for the first time that a specific DP IV inhibitor in a given dose was able to completely block glucagon-like peptide-1 (GLP-1) degradation in vivo resulting in improved insulin response accompanied, by accelerated peripheral glucose disposal.
77 16077164 Activation of the glucagon-like peptide-1 (GLP-1) receptor on pancreatic beta cells by GLP-1 and exendin-4 increases insulin secretion.
78 16087719 In cells from STZ-rats the magnitude of the above parameters was, in general, comparable to that in normal animals, with some exceptions: basal PI3K activity and lipogenesis were higher, GLP-1, Ex-4 and Ex-9 failed to modify basal lipogenesis but increased PKB activity, insulin failed to affect the activity of MAPKs and the insulin-induced glucose uptake was impaired.
79 16179267 GLP-1 stimulates insulin secretion, delays gastric emptying, decreases glucagon levels and reduces appetite, all resulting in a fall in plasma glucose concentrations.
80 16188169 Glucagon-like peptide-1 (GLP-1) is an intestinal hormone that promotes glucose homeostasis through the regulation of insulin and glucagon secretion, gastric emptying, and food intake.
81 16517403 Furthermore, GLP-1, unlike GIP, potently stimulates insulin secretion and reduces blood glucose in human subjects with type 2 diabetes.
82 16505481 GLP-1 induces glucose-dependent insulin secretion in the pancreas, whereas glucagon stimulates gluconeogenesis and glycogenolysis in the liver.
83 16995414 Incretin effect of glucose-dependent insulinotropic peptide (GIP) and glucagon-like peptide 1 (GLP-1) is significantly involved in the insulin secretion which is modulated by many other hormones.
84 17003289 This study examined the effects of glucagon-like peptide-1 (GLP-1) on insulin secretion alone and in combination with sulphonylureas or nateglinide, with particular attention to K(ATP) channel-independent insulin secretion.
85 17003289 In depolarised cells, GLP-1 significantly augmented glucose-induced K(ATP) channel-independent insulin secretion in a glucose concentration-dependent manner.
86 17003289 In contrast, GLP-1 exhibited a reduced but still significant insulin-releasing effect following PKA and PKC downregulation, indicating that GLP-1 can modulate K(ATP) channel-independent insulin secretion by protein kinase-dependent and -independent mechanisms.
87 17003289 The synergistic insulin-releasing effects of combinatorial GLP-1 and sulphonylurea/nateglinide were lost following PKA- or PKC-desensitisation, despite GLP-1 retaining an insulin-releasing effect, demonstrating that GLP-1 can induce insulin release under conditions where sulphonylureas and nateglinide are no longer effective.
88 16621111 Glucagon-like peptide-1 (GLP-1) is an intestinal insulinotropic hormone that augments glucose induced insulin secretion, and has a trophic effect on beta-cells.
89 17065392 GLP-1(9-36)amide also had no effect on plasma glucose homeostasis or insulin secretion.
90 17289847 Unlike receptors for GLP-1 and other peptides that mediate enhanced glucose-dependent insulin release, GPR119 was suitable for the development of potent, orally active, small-molecule agonists.
91 17444618 They bind and activate the pancreatic GLP-1 receptor (GLP-1R) with similar affinity and potency and thereby promote insulin secretion in a glucose-dependent manner.
92 17609256 The endogenous secretion of GIP or GLP-1 was unrelated to the changes in insulin clearance.
93 17609256 Likewise, infusing GLP-1 during a meal course did not alter insulin clearance (P = 0.87).
94 17609256 Neither GIP nor GLP-1 has significant effects on insulin extraction.
95 17724330 Glucagon-like peptide-1 (GLP-1), released from gut endocrine L cells in response to glucose, regulates appetite, insulin secretion, and gut motility.
96 17877544 Activities of the dominant incretins, glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic peptide, include glucose-dependent stimulation of insulin secretion and, in preclinical models, improvement in islet beta-cell mass.
97 18078308 The in vitro insulinotropic effects of DB-GLP-1 and DBP-GLP-1 showed potent biological activity in a dose-dependent manner, which resembled that of native GLP-1 in terms of stimulating insulin secretion in isolated rat islets of Langerhans.
98 18478125 The incretin hormone GLP-1, which is used in clinical practice suppressed iNOS and ncNOS expression and activity with almost full restoration of insulin release and partial restoration of glucagon release.
99 18556349 Our data show that a 1-month chronic blockage of brain GLP-1 signaling by exendin-9 (Ex9), totally prevented hyperinsulinemia and insulin resistance in HFD mice.
100 18556349 Thus, we have demonstrated that in response to a HFD, brain GLP-1 signaling induces hyperinsulinemia and insulin resistance and decreases energy expenditure by reducing metabolic thermogenesis and ambulatory activity.
101 18835930 The GLP-1 and gastrin combination increased pancreatic insulin content, beta-cell mass, and insulin-positive cells in pancreatic ducts, and beta-cell apoptosis was decreased.
102 18987435 A high concentration of GLP-1 (10 nM) stimulated intracellular cAMP accumulation and insulin secretion was significantly inhibited by KT5720, a selective inhibitor of PKA.
103 18987435 Insulin secretion stimulated by 1 pM GLP-1 was reduced by inhibitors of calcium action, including verapamil, dantrolene, and BAPTA.
104 18435775 In humans, GLP-1 stimulates insulin secretion and inhibits glucagon and gastrointestinal secretions and motility.
105 19074620 GLP-1, on the other hand, is still insulinotropic in T2DM, and this has led to the development of compounds that activate the GLP-1 receptor with a view to improving insulin secretion.
106 19170358 Besides classical sulfonylureas and glinides, new insulin secretagogues are now available, which target the incretin gut hormone glucagon-like peptide-1 (GLP-1).
107 19208912 Application of OEA (10 micromol/l) directly into the rat ileum, but not intravenously, increased plasma bioactive GLP-1 levels in euglycemic animals by 1.5-fold (P < 0.05) and insulin levels by 3.9-fold (P < 0.01) but only in the presence of hyperglycemia.
108 19365392 This is evident from the recent success of glucagon-like peptide 1 (GLP1) mimetics and dipeptidyl peptidase 4 (DPP4) inhibitors, which promote activation of the GLP1 receptor to stimulate insulin secretion and inhibit glucagon secretion, and also have the potential to increase beta-cell mass.
109 19332449 Glucagon-like peptide-1 (GLP-1) is an incretin hormone that potentiates insulin secretion in a glucose-dependent manner.
110 19418936 It potentiates the insulin secretory response (incretin effect) by enhancing the endogenous post-prandial response of GLP-1 (incretin enhancer) in a glucose-dependent manner.
111 19591659 Incretins such as glucagon-like peptide-1 (GLP-1) are gut-derived hormones that stimulate insulin secretion and suppress glucagon secretion, thus playing a key role in glucose homeostasis.
112 19591659 Small exploratory studies suggest that GLP-1 safely reduces hyperglycemia without causing hypoglycemia, a key advantage over insulin if efficacy is established in larger studies.
113 19767827 Glucagon-like peptide-1 (GLP-1) ameliorates the symptoms of diabetes through stimulation of insulin secretion.
114 19791828 This increases GLP-1 levels, stimulates insulin secretion and reduces postprandial glucagon and glucose levels.
115 19766107 The dipeptidyl peptidase (DPP)-IV inhibitor ASP8497, (2S,4S)-4-fluoro-1-({[4-methyl-1-(methylsulfonyl)piperidin-4-yl]amino}acetyl)pyrrolidine-2-carbonitrile monofumarate, inhibits the degradation of glucagon-like peptide-1 (GLP-1), an incretin hormone, and promotes insulin secretion in a glucose-dependent manner.
116 19698772 In intraperitoneal glucose tolerance testing in rats, marked improvement of hypoglycemic effects were observed in anionic liposomal formulation of GLP-1 (100 nmol/kg) with 1.7-fold higher increase of insulin secretion, as compared to GLP-1 solution.
117 19947814 The incretin effect, mediated by glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP), plays an important role in the regulation of insulin secretion in response to oral glucose.
118 19947815 Glucagon-like peptide-1 (GLP-1) is a gastrointestinal hormone from the incretin family, which stimulates insulin secretion and plays an important role in regulating the enteroinsular axis.
119 19664300 Since GLP-1 may increase insulin sensitivity and secretion, these results may provide a mechanism for the epidemiological association between high cereal fibre intake and reduced risk for diabetes.
120 19918005 Improvement in postprandial glucose metabolism after gastric bypass is an immediate and direct consequence of the gastrointestinal rearrangement, associated with exaggerated GLP-1 release and independent of changes in insulin sensitivity, weight loss, and caloric restriction.
121 19933995 Insulin secretion stimulated by glucose, amino acids, and glucagon-like peptide-1 (GLP-1) was significantly elevated in the transgenic islets.
122 19128990 Glucagon-like peptide-1 (GLP-1) analogues and inhibitors of its degrading enzyme, dipeptidyl peptidase IV (DPPIV), are interesting therapy options in human diabetics because they increase insulin secretion and reduce postprandial glucagon secretion.
123 20421298 The intestinal peptides GLP-1 and GIP potentiate glucose-mediated insulin release.
124 20610567 When expressed in Neuro2A and COS7 cells, an active form of GLP-1 was specifically detected by RIA in the conditioned medium of transduced cells, showed resistance to degradation by dipeptidyl-peptidase IV, and induced the secretion of insulin from NIT1 pancreatic beta-cells in vitro.
125 19732123 In an intraperitoneal glucose tolerance test, Zucker diabetic fatty rats receiving 2 mg GLP-1 Technosphere Powder (0.3 mg GLP-1) by pulmonary insufflation exhibited lower glucose concentrations and higher insulin concentrations than control rats.
126 19817784 GPR119 is expressed in pancreatic beta-cells and enteroendocrine L-cells, and augments circulating insulin levels both through its direct insulinotropic action on beta-cells and through FA stimulation of glucagon-like peptide 1 (GLP-1) secretion.
127 19878257 Glucagon-like peptide-1 (GLP-1) is an incretin hormone that is known to stimulate glucose-dependent insulin secretion.
128 19878258 The incretin hormones, such as glucagon-like peptide-1 (GLP-1), induce the glucose-dependent secretion of insulin, improve beta-cell function and induce slowing of gastric emptying and feelings of satiety - which result in reduced food intake and weight loss.
129 19920937 Incretin glucagon-like peptide-1 (GLP-1) is a hormone released from cells in the gastrointestinal tract (GI), leading to glucose-dependent insulin release from the pancreas.
130 20152736 Post-prandial GLP-1 and GIP levels increase after GBP and the incretin effect on insulin secretion normalizes to the level of non diabetic controls.
131 20519242 New intravenous or oral agents include the incretin glucagon-like peptide 1 (GLP1), its analogues, and dipeptidyl peptidase-4 inhibitors, which potentiate the activity of GLP1 and thus enhance glucose-dependent insulin secretion.
132 20580750 This study investigated the glucagon-releasing properties of the hormones glucagon-like peptide-2 (GLP-2) and glucose-dependent insulinotropic polypeptide (GIP) in 8 patients with type 1 diabetes mellitus (T1DM) without paracrine intraislet influence of insulin (C-peptide negative following a 5 g intravenous arginine stimulation; on study days only treated with basal insulin substitution).
133 20590744 Taspoglutide showed typical effects of native GLP-1, with improvement in glucose tolerance, postprandial glucose, body weight, glycaemic control and insulin sensitivity.
134 20590751 It can be concluded from the study that GLP-1 can induce reactive hypoglycaemia in pancreas transplant recipients through excessive insulin secretion associated with an increased insulin-to-glucagon ratio.
135 20658367 The mechanism may be associated with the increase of serum GLP-1 and ghrelin and the decrease of serum leptin and insulin resistance.

138 20809667 Of the incretin-based therapies, both the dipeptidyl peptidase-4 (DPP-4) inhibitors and the glucagon-like peptide-1 (GLP-1) receptor agonists stimulate insulin secretion and inhibit glucagon secretion.
139 20824239 In addition to improving insulin resistance and pancreatic ?-cell dysfunction, the GLP-1 agonists and DPP-4 inhibitors improve the impaired incretin response, as well as increase insulin secretion and reduce glucagon secretion, both in a glucose-dependent manner.
140 21086586 It increases the circulating levels of incretin hormones (GLP-1, GIP), which contributes to amplify the insulin secretory response to meals and to reduce postprandial hyperglycaemia and, subsequently, fasting glycaemia.
