Introduction The beneficial effects of glucagon-like peptide 1 (GLP-1) and its related substances such as inhibitors of dipeptidyl peptidase IV, its degrading enzyme, on the pancreatic β-cells have been reported; these agents enhance

Introduction The incretin hormones, glucagon-like peptide-1 (GLP1) and glucose-dependent insulinotropic polypeptide (GIP) strongly potentiate postprandial insulin secretion and are therefore important regulators of glucose homeostasis. They are

under investigation for NASH, glucagon-like peptide-1 receptor agonists (GLP-1RAs) have shown a significant promise for the treatment of NAFLD ( Ding et al. 2006 , Blonde & Russell-Jones 2009 , Cusi 2012 , Armstrong et al. 2013 , 2016 a , b

Introduction Intracellular cAMP is crucial for pancreatic β-cell function. Insulin secretion stimulated by glucagon and incretin hormones, e.g. glucagon-like peptide-1 (GLP-1), is exerted via increased cAMP ( Gromada et al. 1998

Introduction Glucagon-like peptide-1 (GLP-1) has been of much interest due to its β-cell-proliferating effect and role as an incretin hormone in synergizing with glucose to enhance insulin release ( Ørskov 1992 , Egan et al. 2003
