Stability of glucagon-like peptide 1 and glucagon in human plasma

To investigate the stability of glucagon-like peptide 1 (GLP-1) and glucagon in plasma under short- and long-term storage conditions. Pooled human plasma (n=20), to which a dipeptidyl peptidase 4 (DPP4) inhibitor and aprotinin were added, was spiked with synthetic GLP-1 (intact, 7-36NH2 as well as the primary metabolite, GLP-1 9-36NH2) or glucagon. Peptide recoveries were measured in samples ke...

Glucagon-Like Peptide-1

Ma Glucagon-like peptide-1-(7-36) amide (GLP-1) is a human incretin hormone responsible for the release of insulin in response to food. Pre-clinical and human physiological studies have demonstrated cardioprotection from ischemia-reperfusion injury. It can reduce infarct size, ischemic left ventricular dysfunction, and myocardial stunning. GLP-1 receptor agonists have also been shown to reduce ...

Effects of Fasting on Glucagon-like peptide-1 hormone (GLP-1), and Lipid Profile Indices in Obese and Thin Women

Introduction: Glucagon-like peptide-1 hormone (GLP-1) contributes to the regulation of insulin and glucose concentration. However, the effects of fasting on GLP-1 response in different people has not been determined yet. The aim of the present research was to investigate the effect of fasting on GLP-1 and the lipid profile of obese and thin women.Materials and methods: In this research, 25 obes...

Direct and indirect mechanisms regulating secretion of glucagon-like peptide-1 and glucagon-like peptide-2.

The proglucagon-derived peptide family consists of three highly related peptides, glucagon and the glucagon-like peptides GLP-1 and GLP-2. Although the biological activity of glucagon as a counter-regulatory hormone has been known for almost a century, studies conducted over the past decade have now also elucidated important roles for GLP-1 as an antidiabetic hormone, and for GLP-2 as a stimula...

EFFECTS OF AEROBIC TRAINING ON DIPEPTIDYL PEPTIDASE-4 AND GLUCAGON-LIKE PEPTIDE-1 IN OBESE WOMEN WITH TYPE 2 DIABETES

Background: Obesity increases the risk of developing type 2 diabetes with regard to the hormones involved. The purpose of this quasi-experimental study was to investigate the effect of aerobic exercise on Dpp-4 and GLP-1 in obese women with type 2 diabetes. Methods: From among obese women with type-2 diabetes mellitus 35-50 years old referred to the Diabetes Association of Saveh, 20 people wer...
