Under acute pancreatitis, high‐performance liquid chromatography (HPLC) revealed AMP levels acutely decrease from Day 1 to Day 4, and increase from Day 4 to Day 7 in wild‐type mice; in contrast, in CD73−/− mice these levels increase from Day 1 to Day 4 and decrease from Day 4 to Day 7, suggesting a transient accumulation of AMP in the context of no CD73 activity (Figure 3B). The gene discussed is NT5E; the disease is acute pancreatitis.
