1 OBJECTIVE: FFAR1/GPR40 is a G-protein-coupled receptor expressed predominantly in pancreatic islets mediating free fatty acid-induced insulin secretion. Fatty Acids, Nonesterified free fatty acid receptor 1 Mus musculus
2 OBJECTIVE: FFAR1/GPR40 is a G-protein-coupled receptor expressed predominantly in pancreatic islets mediating free fatty acid-induced insulin secretion. Fatty Acids, Nonesterified free fatty acid receptor 1 Mus musculus
3 A more recent report suggested that although FFAR1 was necessary for fatty acid-induced insulin secretion in vivo, deletion of FFAR1 did not protect pancreatic islets against fatty acid-induced islet dysfunction. Fatty Acids free fatty acid receptor 1 Mus musculus
4 RESULTS: Insulin secretion was reduced by approximately 50% in Ffar1(-/-) mice, confirming that FFAR1 contributes significantly to fatty acid stimulation of insulin secretion in vivo. Fatty Acids free fatty acid receptor 1 Mus musculus
5 RESULTS: Insulin secretion was reduced by approximately 50% in Ffar1(-/-) mice, confirming that FFAR1 contributes significantly to fatty acid stimulation of insulin secretion in vivo. Fatty Acids free fatty acid receptor 1 Mus musculus
6 CONCLUSIONS: FFAR1 is required for normal insulin secretion in response to fatty acids; however, Ffar1(-/-) mice are not protected from high-fat diet-induced insulin resistance or hepatic steatosis. Fatty Acids free fatty acid receptor 1 Mus musculus
