Figure 5.Circulating plasma GLP-1 level is increased in DPP4-deficient rats. Plasma GLP-1 concentration was measured using rat-specific GLP-1 ELISA kit within 3 h after collecting blood from wild-type and DPP4-deficient rats at 8 weeks of age. Data are shown as the means ± SEM. *p < 0.05 and WT, n = 4–6 per group.
