Mice were fasted for 15–16 h overnight prior to intraperitoneal (IPGTT) and oral glucose tolerance tests (OGTT) with free access to water. Blood samples were taken for glycemia measurement via venesection of the tail vein. Glycemia was measured using an Accu-Chek glucometer (Roche Diabetes Care, UK) and appropriate measurement strips. Fasting glycemia was first measured (time 0), and then glucose was administered via ip injection (1 g/kg body wt) or oral gavage (1.5 g/kg body wt). Glycemia measurements were then taken by injection at 15, 30, 45, 60, 90, and 120 min.
