Background  The cystic fibrosis (CF) mouse pancreas has constitutively elevated expression of the  Reg/PAP  cell stress genes (60-fold greater  Reg3α , and 10-fold greater  PAP/Reg3β  and  Reg3γ ). These genes are suggested to be involved in protection or recovery from pancreatic injury.    Methods  To test this idea the supramaximal caerulein model was used to induce acute pancreatitis in wild type and CF mice. Serum amylase, pancreatic water content (as a measure of edema), pancreatic myeloperoxidase activity, and  Reg/PAP  expression were quantified.    Results  In both wild type and CF mice caerulein induced similar elevations in serum amylase (maximal at 12 h), pancreatic edema (maximal at 7 h), and pancreatic myeloperoxidase activity (MPO, a marker of neutrophil infiltration; maximal at 7 h). By immunohistochemistry, Reg3α was strongly expressed in the untreated CF pancreas but not in wild type. During pancreatitis, Reg3α was intensely expressed in foci of inflamed tissue in both wild type and CF.    Conclusion  These data demonstrate that the severity of caerulein-induced pancreatitis is not ameliorated in the CF mouse even though the  Reg/PAP  stress genes are already highly upregulated. While Reg/PAP may be protective they may also have a negative effect during pancreatitis due to their anti-apoptotic activity, which has been shown to increase the severity of pancreatitis.
