Abstract:
Glucagon-like peptide-1 (GLP-1), which has been extensively applied for treating type 2 diabetes mellitus (T2DM), is an incretin hormone that regulates glucose homeostasis. GLP-1(28-36)amide, a C-terminal nonapeptide (FIAWLVKGRamide) of GLP-1, is a major product derived from the cleavage of GLP-1 by the neutral endopeptidase (NEP). GLP-1(28-36)amide has long been regarded as a metabolically inactive byproduct, however, recent findings reveal that GLP-1(28-36)amide plays multiple novel roles in ameliorating hepatic metabolism, protecting β cells, improving glucose disposal and inhibiting weight gain. Here, we summarize the latest progress on the effects of GLP-1(28-36)amide with a focus on its roles in regulating the Wnt and mitochondrial-mediated signaling pathways.
