Figure 6From: DPP-4 inhibitor linagliptin ameliorates cardiovascular injury in salt-sensitive hypertensive rats independently of blood glucose and blood pressureEffect of linagliptin on serum DPP4 activity, GLP-1, insulin, and glucose levels of high salt-loaded DS rats. Each panel indicates relative DPP-4 activity (A), GLP-1 (B), serum insulin (C), and serum glucose (D). Abbreviations used are the same as in Figure 1. Each value represents mean ± SEM (n = 7 in Normal Na, n = 11 in Veh, n = 10 in Lin).Back to article page
