Figure 4. Islet and incretin hormonal responses to hyper- and hypoglycemia in ferrets.
Serum samples were from the hyperglycemic→hypoglycemic clamps shown in Figure 3. (A) Glucagon, (B) pancreatic polypeptide (PP), (C) GLP-1, and (D) GIP were measured. * p<0.05 versus 120 min time-point (N = 7). There were no significant changes compared to baseline during hyperglycemia.
