Novel and effective drugs against acute pancreatitis are required. Therefore, we examined the changes in the metabolite levels in the serum and pancreatic tissue of mice with cerulein- and arginine-induced pancreatitis using gas-chromatography/mass-spectrometry (GC/MS) and investigated whether these alterations affected the severity of acute pancreatitis. In the cerulein-induced pancreatitis model, 93 and 129 metabolites were detected in the serum and pancreatic tissue, respectively. In the l-arginine-induced acute pancreatitis model, 120 and 133 metabolites were detected in the serum and pancreatic tissue, respectively. Among the metabolites, the concentrations of tricarboxylic acid (TCA) cycle intermediates and amino acids were altered in pancreatitis, and in pancreatic tissue, the levels of the intermediates involved in the initial part of the TCA cycle were increased and those of the intermediates involved in the latter part of the TCA cycle were decreased. Some metabolites exhibited similar changes in both pancreatitis mouse models, e.g., the levels of glutamic acid and O-phosphoethanolamine were significantly decreased in the pancreatic tissue. Supplementation with glutamic acid and O-phosphoethanolamine attenuated the severity of cerulein-induced acute pancreatitis. Our results suggest that GC/MS-based metabolomics is capable of accurately representing the status of acute pancreatitis, leading to the discovery of therapeutic agents for pancreatitis.
