Tissue concentration of GLP-1, GLP-2 and GLI/OX in mouse, rat and pig. Distribution of proglucagon derived peptides along the gastrointestinal tract in mice, rats and pigs. Data are shown as relative means ± 1SEM (compared to overall average for the respective species). a GLP-1 total, b GLP-2 (intact) and GLI/OX (total) for duodenum (D), proximal jejunum, (PJ), distal ileum (DI), caecum (C), proximal colon (PC) and distal colon (DC). Significance is indicated above respective bars. Significant different (P < 0.05) from a duodenum, b proximal jejunum, c distal ileum, d caecum, e proximal colon and f distal colon
