Caerulein-induced acute pancreatitis in mice that constitutively overexpress Reg/PAP genes.

ABSTRACT:

Background

The cystic fibrosis (CF) mouse pancreas has constitutively elevated expression of the Reg/PAP cell stress genes (60-fold greater Reg3alpha, and 10-fold greater PAP/Reg3beta and Reg3gamma). 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 infiltr
