We have previously shown that the acute phase reaction of the pancreas is a powerful emergency mechanism which protects the organism against further pancreatic aggression. In an attempt to understand the mechanisms involved in this protective effect we tried to characterize at the molecular level the phenotypic changes of the pancreatic cell during acute stress. Using a systematic approach, we identified the PC3/TIS21/BTG2 mRNA as strongly overexpressed in pancreas during the acute phase of pancreatitis. PC3/TIS21/BTG2 mRNA is also overexpressed in liver and kidney during acute pancreatitis but not in the other tissues analyzed. In addition, PC3/TIS21/BTG2 mRNA is overexpressed in kidney after a 30-min ischemia. Since acute pancreatitis and kidney ischemia-reperfusion-induced injury were associated with apoptosis, and PC3/TIS21/BTG2 has an antiapoptotic activity, we speculate that this protein may play a role in the control of apoptosis progression in these tissues.

Most attacks of acute pancreatitis display a self-limiting course. This suggests that pancreatic acinar cells may be able to protect themselves against cellular injury thus preventing further progression of the disease. In this review we describe several genes overexpressed in acute experimental pancreatitis which take part in the pancreatic stress response. We discuss the possible function of the pancreatitis-associated protein 1, the small nuclear protein p8, the glycoprotein clusterin, different heat shock proteins, the p53-dependent stress proteins TP53INP1alpha and TP53INP1beta, the vacuole membrane protein-1, as well as the interferon-inducible protein-15, the antiproliferative p53-dependent protein PC3/TIS21/BTG2, and the pancreatitis-induced protein-49. The implications of these proteins in pathophysiological processes like apoptosis regulation, regeneration, cell cycle and growth control, regulation of inflammation, and vacuole formation are discussed. Study of the function of stress proteins expressed in response to pancreatitis could widen our understanding of the pathophysiology of the disease and enable us to develop new rational therapeutic strategies.
