Glucagon-like peptide-1 (GLP-1) an incretin hormone, is known to regulate the glucose-mediated insulin secretion. However, reduction in the level of GLP-1 is considered to be a major cause for the reduction of GLP-1-dependent insulin secretory response. Genistein an isoflavone, is an important polyphenol and has wide range of therapeutic potentials, but its therapeutic effects alone and/or in combination with metformin on GLP-1 secretion have not been investigated yet. Hence, we aimed to investigate the stimulatory action of genistein in combination with metformin on GLP-1 via downregulation of inflammatory mediators, hyperlipidemia and hyperglycemia in alloxan-induced diabetic rats...

BACKGROUND: Gastric bypass with a proximal gastric pouch (Roux-en-Y gastric bypass) induces early diabetes remission. The effect of gastric bypass with a distal gastric pouch remains unknown. OBJECTIVE: To observe the effect on glucose tolerance and diabetes remission of gastric bypass with a distal gastric pouch. METHOD: A type 2 diabetes (T2D) model was created in 44 Sprague-Dawley (SD) rats that randomly underwent Roux-en-Y gastric bypass (RYGB, n = 8); gastric bypass with duodenal-jejunal transit (GB-DJT, n = 8); distal-pouch gastric bypass with duodenal-jejunal transit (DPGB-DJT, n = 8); distal-pouch gastric bypass with duodenal-jejunal bypass (DPGB-DJB, n = 8); sham (n = 6); and Roux-en-Y gastric bypass with esophageal re-anastomosis (RYGB-Er, n = 6) surgery...

PURPOSE: Liraglutide, a glucagon-like peptide-1 (GLP-1) analogue, is an antidiabetic drug. It has been shown to improve the Psoriasis Area and Severity Index (PASI) in patients with type 2 diabetes and psoriasis in clinical practice, but the mechanism remains somewhat unclear. We used lipopolysaccharides (LPS) to induce inflammatory response in keratinocytes and explore the mechanism. METHODS: The HaCat cells were incubated with LPS for 16 h and then were treated with liraglutide for 30 min...

Plant materials have been widely studied for their preventive and therapeutic effects for type 2 diabetes mellitus (T2DM) and obesity. The effect of a plant material arises from its constituents, and the study of these bioactive compounds is important to achieve a deeper understanding of its effect at the molecular level. In particular, the study of the effects of such bioactive compounds on various biological processes, from digestion to cellular responses, is required to fully understand the overall effects of plant materials in these health contexts...

Dulaglutide, a novel long-acting glucagon-like peptide 1 (GLP-1) receptor agonist, is an incretin mimetic approved for type 2 diabetes mellitus (T2DM) treatment. Alzheimer's disease (AD) is called type 3 diabetes. The aim of this study is to explore the effects of dulaglutide on the learning and memory impairment in AD mice induced by injection of streptozocin (STZ) via intracerebroventricularly (i.c.v.). 32 male C57/BL6 mice were randomly divided into four groups: control group (CON); AD model group (STZ); dulaglutide treated (Dul); dulaglutide and exendin(9-39) (Ex)...

OBJECTIVE: Postprandial hyperinsulinaemia after Roux-en Y gastric bypass (GB) has been attributed to rapid nutrient flux from the gut, and an enhanced incretin effect. However, it is unclear whether surgery changes islet cell responsiveness to regulatory factors. This study tested the hypothesis that β-cell sensitivity to glucagon like-peptide 1 (GLP-1) and glucose-dependent insulinotropic peptide (GIP) is attenuated after GB. DESIGN: Ten non-diabetic subjects with GB, and 9 body mass index (BMI)-matched and age-matched non-surgical controls (CN) with normal glucose tolerance had blood glucose clamped at ~7...

AIMS: High glucose (HG)-induced pancreatic β-cell apoptosis may be a major contributor to the progression of diabetes mellitus (DM). NADPH oxidase (NOX2) has been considered a crucial regulator in β-cell apoptosis. This study was designed to evaluate the impact of GLP-1 receptor agonist (GLP-1Ra) liraglutide on pancreatic β-cell apoptosis in diabetes and the underlying mechanisms involved. METHODS: The diabetic rat models induced by streptozotocin (STZ) and a high fat diet (HFD) received 12 weeks of liraglutide treatment...

The glucagon receptor (GCGR) is emerging as an important target in anti-diabetic therapy, especially as part of the pharmacology of dual glucagon-like peptide-1/glucagon (GLP-1/GCG) receptor agonists. However, currently, there are no suitable biomarkers that reliably demonstrate GCG receptor target engagement. METHODS: Two potent GCG receptor peptide agonists, S01-GCG and S02-GCG, were labeled with positron emission tomography (PET) radionuclide gallium-68. The GCG receptor binding affinity and specificity of the resulting radiopharmaceuticals [68 Ga]Ga-DO3A-S01-GCG and [68 Ga]Ga-DO3A-S02-GCG were evaluated in HEK-293 cells overexpressing the human GCG receptor and on frozen hepatic sections from human, non-human primate, and rat...

Glucagon-like peptide-1 (GLP-1) and its receptor, GLP-1R, are valuable tools in the therapy of type 2 diabetes mellitus. Although GLP-1R stimulation is also potentially applicable to neurological disorders, few investigators have evaluated its beneficial effects in neurological disease models. Thus, we aimed to look into the antiepileptic effects of GLP-1R on epilepsy and its underlying mechanisms. The cerebral cortex of 22 patients with temporal lobe epilepsy (TLE) and 16 patients with trauma were collected to the epilepsy and control groups, respectively...

Inflammation and oxidative stress are the two processes crucial in atherogenesis. Platelet-activating factor acetylhydrolase (PAF-AH), a plasma lipoprotein-associated enzyme, degrades pro-inflammatory lipids generated within oxidatively modified lipoproteins. Extensive evidence shows that incretin-based drugs, a new class of anti-diabetic agents, can provide cardiovascular protection that cannot be attributed to their glucose-lowering effects. The present study was undertaken to determine whether the antiatherogenic effects of the GLP-1(glucagon-like peptide-1) receptor agonist (exenatide) and DPP-4(dipeptidyl peptidase-4) inhibitors (sitagliptin) may occur via the regulation of platelet-activating factor acetylhydrolase (PAF-AH) activity/mass and inhibition of low-density lipoprotein (LDL) oxidation in the fructose-fed rats...

Semaglutide is a glucagon-like peptide-1 receptor agonist (GLP-1 RA) with a long elimination half-life, allowing subcutaneous (sc) administration once per week. Both the European Medicines Agency (EMA) and the Food and Drug Administration (FDA) recently approved once-weekly sc semaglutide for the treatment of type 2 diabetes mellitus (T2DM). The weight loss efficacy of once-weekly sc semaglutide appears to be superior compared with the other once-weekly GLP-1 RAs in patients with T2DM. Semaglutide was recently evaluated as an antiobesity drug in a phase II dose-finding trial, which demonstrated superior weight loss efficacy of once daily sc semaglutide compared with both placebo and once daily 3...

Prakash Deedwania, Tushar Acharya
Diabetes mellitus is a major risk factor for cardiovascular (CV) disease. Conversely, CV disease is responsible for a majority of the deaths in patients with diabetes. Many drug trials have concentrated on blood glucose (hemoglobin A1c ) reduction. This strategy, while reducing microvascular outcomes like nephropathy and neuropathy, has little or no effect on reducing macrovascular events like heart attack, stroke, and heart failure. It has been postulated that hypoglycemia may counterbalance some of the beneficial effects of anti-hyperglycemic agents, but this is not proven...

OBJECTIVE: Cells releasing glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide 1 (GLP-1) are distributed predominately in the proximal and distal gut, respectively. Hence, the region of gut exposed to nutrients may influence GIP and GLP-1 secretion and impact on the incretin effect and gastrointestinal-mediated glucose disposal (GIGD). We evaluated glycemic and incretin responses to glucose administered into the proximal or distal small intestine and quantified the corresponding incretin effect and GIGD in health and type 2 diabetes mellitus (T2DM)...

INTRODUCTION: Few data exist examining the effects of whole grain (WG) versus refined grain (RG) diets on glucose-stimulated insulin secretion (GSIS) and β-cell function. METHODS: In a double-blind crossover randomized controlled trial, 13 sedentary prediabetic adults (37.2±1.8 y, BMI: 33.6±1.4 kg/m2 , 2h glucose: 146.9±11.6 mg/dl) were provided isocaloric-matched WG and RG diets for 8-weeks each, with an 8-10 week washout between diets. Glucose, insulin and C-peptide metabolism was studied over 240 min following a 75g OGTT...

The American Association of Clinical Endocrinologists (AACE) has created a dysglycemia-based chronic disease (DBCD) multimorbidity care model consisting of four distinct stages along the insulin resistance-prediabetes-type 2 diabetes (T2D) spectrum that are actionable in a preventive care paradigm to reduce the potential impact of T2D, cardiometabolic risk, and cardiovascular events. The controversy of whether there is value, cost-effectiveness, or clinical benefit of diagnosing and/or managing the prediabetes state is resolved by regarding the problem, not in isolation, but as an intermediate stage in the continuum of a progressive chronic disease with opportunities for multiple concurrent prevention strategies...

Dipeptidyl peptidase 4 (DPP4) is an exopeptidase found either on cell surfaces where it is highly regulated in terms of its expression and surface availability (CD26) or in a free/circulating soluble constitutively available and intrinsically active form. It is responsible for proteolytic cleavage of many peptide substrates. In this review we discuss the idea that DPP4-cleaved peptides are not necessarily inactivated, but rather can possess either a modified receptor selectivity, modified bioactivity, new antagonistic activity, or even a novel activity relative to the intact parent ligand...

Chronic kidney disease (CKD) in patients with diabetes mellitus (DM) is a major problem of public health. Currently, many of these patients experience progression of cardiovascular and renal disease, even when receiving optimal treatment. In previous years, several new drug classes for the treatment of type 2 DM have emerged, including inhibitors of renal sodium-glucose co-transporter-2 (SGLT-2) and glucagon-like peptide-1 (GLP-1) receptor agonists. Apart from reducing glycaemia, these classes were reported to have other beneficial effects for the cardiovascular and renal systems, such as weight loss and blood pressure reduction...
