A Study to Evaluate the Effect of Genetic Variation on Beta-cell Function During Fasting and Hyperglycemia in Nondiabetics
November 21, 2022 updated by: Adrian Vella
Effect of Genetic Variation in the GLP-1 Receptor on Beta-cell Function During Fasting and Hyperglycemia in Nondiabetic Humans
The GLP-1 receptor (GLP1R) gene is found on the beta cells of the pancreas.
Its role is in the control of blood sugar level by enhancing insulin secretion from the pancreas after eating a meal.
The purpose of this research study to find out how genetic variations in GLP1R alter insulin secretion, in the fasting state and when blood sugars levels are elevated.
