Calcium release of HEK cells expressing GIPR or GLP-1R or coexpressing GLP-1R with another glucagon receptor
The EC50 and Hill slope values from independent experiments were averaged and compared for each condition, with GIPR (GIP, n = 4; GLP-1, n = 4), GLP-1R (GIP, n = 4; GLP-1, n = 5), GLP-1R plus GIPR (GIP, n = 4; GLP-1, n = 4), GLP-1R plus GlucR (GLP-1, n = 3), and GLP-1R plus GLP-2R (GLP-1, n = 3).
