ab26278 (1μg/ml) staining GLP-1 in Human pancreas, using an automated system (DAKO Autostainer Plus). Using this protocol there is strong cytoplasmic staining.
Sections were rehydrated and antigen retrieved with the Dako 3 in 1 AR buffer citrate pH6.1 in a DAKO PT link. Slides were peroxidase blocked in 3% H2O2 in methanol for 10 mins. They were then blocked with Dako Protein block for 10 minutes (containing casein 0.25% in PBS) then incubated with primary antibody for 20 min and detected with Dako envision flex amplification kit for 30 minutes. Colorimetric detection was completed with Diaminobenzidine for 5 minutes. Slides were counterstained with Haematoxylin and coverslipped under DePeX. Please note that, for manual staining, optimization of primary antibody concentration and incubation time is recommended. Signal amplification may be required.

Supplementary information

GLP-1 also known as glucagon-like peptide-1 is a 30 or 31 amino acid peptide with a mass of approximately 3.3 kDa. This peptide is mainly secreted by intestinal L-cells and the CNS. It enhances the secretion of insulin in response to glucose making it an important regulator of blood sugar levels. GLP-1 is degraded by dipeptidyl peptidase-4 which rapidly reduces its activity. Researchers often target GLP-1 in studies aimed at understanding metabolic processes and developing therapeutic interventions.
Biological function summary

GLP-1 influences several physiological functions by acting on its receptor GLP-1R a G-protein coupled receptor. It is not part of a complex but exerts its effects through binding to this receptor. Activation of GLP-1R promotes insulin secretion suppresses glucagon release slows gastric emptying and promotes satiety. This makes GLP-1 an important regulator in energy homeostasis and nutrient absorption. Its effects on appetite and food intake are of particular interest in obesity research.

Pathways

GLP-1 is an essential component of the incretin pathway which regulates insulin secretion in response to food intake. The interaction between GLP-1 and the GLP-1 receptor activates the adenylate cyclase pathway leading to increased cAMP and PKA signaling in pancreatic beta-cells. This chain of events enhances the insulin-secreting ability of these cells. Furthermore GLP-1 has connections with proteins such as insulin and glucagon through its regulatory functions in glucose metabolism.

GLP-1 is highly relevant to type 2 diabetes and obesity. Its ability to enhance insulin secretion and promote weight loss has made it a target for drug development in the treatment of these conditions. Antidiabetic medications including GLP-1 receptor agonists exploit this mechanism to control blood sugar levels effectively. Additionally GLP-1's connection to insulin makes it a significant focus in diabetes research as imbalances in these proteins contribute to the disease pathology.

Target data

Glucagon. Plays a key role in glucose metabolism and homeostasis. Regulates blood glucose by increasing gluconeogenesis and decreasing glycolysis. A counterregulatory hormone of insulin, raises plasma glucose levels in response to insulin-induced hypoglycemia. Plays an important role in initiating and maintaining hyperglycemic conditions in diabetes. Binds to and activates the glucagon receptor GCGR, which couples to the G(s) G protein and elevates intracellular cAMP, triggering downstream metabolic responses (PubMed : 32193322).. Glucagon-like peptide 1. Potent stimulator of glucose-dependent insulin release (PubMed : 22037645, PubMed : 40446798). Also stimulates insulin release in response to IL6 (PubMed : 22037645). Plays important roles on gastric motility and the suppression of plasma glucagon levels (PubMed : 10605628, PubMed : 14719035, PubMed : 12554744). May be involved in the suppression of satiety and stimulation of glucose disposal in peripheral tissues, independent of the actions of insulin (PubMed : 10605628, PubMed : 14719035, PubMed : 12554744). Has growth-promoting activities on intestinal epithelium (PubMed : 10605628, PubMed : 14719035, PubMed : 12554744). May also regulate the hypothalamic pituitary axis (HPA) via effects on LH, TSH, CRH, oxytocin, and vasopressin secretion (PubMed : 10605628, PubMed : 14719035, PubMed : 12554744). Increases islet mass through stimulation of islet neogenesis and pancreatic beta cell proliferation (PubMed : 10605628, PubMed : 14719035, PubMed : 12554744). Inhibits beta cell apoptosis (PubMed : 10605628, PubMed : 14719035, PubMed : 12554744).. Glucagon-like peptide 2. Stimulates intestinal growth and up-regulates villus height in the small intestine, concomitant with increased crypt cell proliferation and decreased enterocyte apoptosis. The gastrointestinal tract, from the stomach to the colon is the principal target for GLP-2 action. Plays a key role in nutrient homeostasis, enhancing nutrient assimilation through enhanced gastrointestinal function, as well as increasing nutrient disposal. Stimulates intestinal glucose transport and decreases mucosal permeability.. Oxyntomodulin. Significantly reduces food intake. Inhibits gastric emptying in humans. Suppression of gastric emptying may lead to increased gastric distension, which may contribute to satiety by causing a sensation of fullness.. Glicentin. May modulate gastric acid secretion and the gastro-pyloro-duodenal activity. May play an important role in intestinal mucosal growth in the early period of life.
