Histologic distribution of insulin and glucagon receptors [PDF]

open access: yesBrazilian Journal of Medical and Biological Research, 1998
Insulin and glucagon are the hormonal polypeptides secreted by the B and A cells of the endocrine pancreas, respectively. Their major physiologic effects are regulation of carbohydrate metabolism, but they have opposite effects. Insulin and glucagon have

Evidence for a lack of inotropic and chronotropic effects of glucagon and glucagon receptors in the human heart

open access: yesCardiovascular Diabetology, 2023
Background Glucagon is thought to increase heart rate and contractility by stimulating glucagon receptors and increasing 3′,5′-cyclic adenosine monophosphate (cAMP) production in the myocardium.

Evaluation of commercially available glucagon receptor antibodies and glucagon receptor expression [PDF]

open access: yesCommunications Biology, 2021
Abstract Glucagon is a major regulator of metabolism and drugs targeting the glucagon receptor (GCGR) are being developed. Insight into tissue and cell-specific expression of the GCGR is important to understand the biology of glucagon and to differentiate between direct and indirect actions of glucagon.

Variation in the Evolution and Sequences of Proglucagon and the Receptors for Proglucagon-Derived Peptides in Mammals

open access: yesFrontiers in Endocrinology, 2021
The mammalian proglucagon gene (Gcg) encodes three glucagon like sequences, glucagon, glucagon-like peptide-1 (GLP-1), and glucagon-like peptide-2 that are of similar length and share sequence similarity, with these hormones having cell surface receptors,

Glucagon Receptor Signaling and Glucagon Resistance [PDF]

open access: yesInternational Journal of Molecular Sciences, 2019
Hundred years after the discovery of glucagon, its biology remains enigmatic. Accurate measurement of glucagon has been essential for uncovering its pathological hypersecretion that underlies various metabolic diseases including not only diabetes and liver diseases but also cancers (glucagonomas).

Glucagon Increases Beating Rate but Not Contractility in Rat Right Atrium. Comparison with Isoproterenol. [PDF]

open access: yesPLoS ONE, 2015
This study evaluated the chronotropic and inotropic responses to glucagon in spontaneously beating isolated right atria of rat heart. For comparison, we also investigated the effects resulting from stimulating β-adrenoceptors with isoproterenol in this ...

Structural Mapping and Functional Characterization of Zebrafish Class B G-Protein Coupled Receptor (GPCR) with Dual Ligand Selectivity towards GLP-1 and Glucagon. [PDF]

open access: yesPLoS ONE, 2016
GLP-1 and glucagon regulate glucose metabolism through a network of metabolic pathways initiated upon binding to their specific receptors that belong to class B G-protein coupled receptors (GPCRs). The therapeutic potential of glucagon is currently being

Delineating the activation mechanism and conformational landscape of a class B G protein-coupled receptor glucagon receptor

open access: yesComputational and Structural Biotechnology Journal, 2022
Class B G protein-coupled receptors (GPCRs) are important targets in the treatment of metabolic syndrome and diabetes. Although multiple structures of class B GPCRs–G protein complexes have been elucidated, the detailed activation mechanism of the ...

Altered cannabinoid receptor expression in pancreatic islets in experimental model of uraemia

open access: yesFolia Morphologica, 2020
BACKGROUND: Uraemia leads to a number of metabolic and hormonal disorders including defective carbohydrate metabolism. Endocannabinoids exert their effect on insulin and glucagon secretion via activation of specific receptors named CB1 and CB2.

A phase 1b randomised controlled trial of a glucagon-like peptide-1 and glucagon receptor dual agonist IBI362 (LY3305677) in Chinese patients with type 2 diabetes

open access: yesNature Communications, 2022
Glucagon-like peptide-1 receptor (GLP1R) agonists are used to treat type 2 diabetes (T2D), and polyagonists targeting multiple hormone receptors are investigated as potential therapeutics for T2D.
