From: Reduced post-operative DPP4 activity associated with worse patient outcome after cardiac surgery
Perioperative analysis of DPP4 activity, CXCL12 and GLP-1. Serum samples were collected before (pre-OP) or at different time points after surgery (0, 6, 12, 24 h post-OP). (a) DPP4 activity in serum samples. n = 6 (controls); 29 ≤ n ≤ 44 (patients). Statistical significance is indicated relative to pre-OP values. (b) CXCL12 serum levels before and at different time points after surgery. 26 ≤ n ≤ 42. Statistical significance is indicated relative to ‘0 h post-OP’ values. (c) Serum levels of total GLP-1 before and at different time points after surgery. n = 9. (a–c) Shown are means ± SD. One-way ANOVA (Kruskal-Wallis) with Dunn’s post-test. *P < 0.05; **P < 0.01; ***P < 0.001. n.s. = not significant.
