We have used a microarray-based strategy to characterize, at the molecular level, the pancreatic emergency program set up by the pancreatic cells in response to pancreatitis. In this strategy, the phenotype of the pancreatitis-affected pancreas is established by characterization of a large number of its transcripts using a high-density mouse cDNA microarray. This method allows identification of transcripts differentially expressed during pancreatitis. We describe here the cloning, sequencing, and expression analysis of a new gene, named PIP49 (Pancreatitis Induced Protein 49). Its very strong expression is specific of acinar cells and occurs rapidly after initiation of the acute phase of pancreatitis. Analysis of its primary and secondary structures strongly suggests that PIP49 encodes a putative transmembrane protein.
