Carbonic anhydrase VIII regulates IP3R1-dependent Ca 2+ signaling to coordinate insulin secretion and hepatic glucose production

Intracellular Ca 2+ signaling is essential for glucose-induced insulin secretion (GIIS) and hepatic glucose production (HGP), yet how Ca 2+ dynamics are coordinated across organs remains unclear. Carbonic anhydrase VIII (CA8), an endogenous inhibitor of inositol 1,4,5-trisphospha...

Olive Oil Before Oral Glucose Delays Gastric Emptying and Lowers Glycemia Through Partially Redundant Glucagon and GLP-1 Signaling in Mice

Consumption of fat before carbohydrate (preload) attenuates postprandial glucose excursions, although the underlying mechanisms remain unclear. We investigated whether an olive oil preload (OG) reduces glycemia by engaging endocrine and neural regulation of gastric emptying. Wild...
