Abstract The mutagen 2-aminoanthracene (2-AA) is an aromatic amine or arylamine, which belongs to a class of polycyclic aromatic hydrocarbons. 2-AA is used in the manufacturing of a wide variety of chemicals, drugs, dyes, and polymers. Non-occupational sources include tobacco smoking and cooked foods. The goal of this study is to evaluate pancreatic gene expression patterns in Fischer-344 (F-344) male rats exposed to 2-AA. As a first step the effects of 2-aminoanthracene exposure on the pancreas with particular interest in genes that relate to insulin and insulin metabolism. To achieve this goal, twenty-four post-weaning, 3-4 week old F-344 male rats were exposed to 0 mg/kg-diet (control), 50 mg/kg-diet (low dose), 75 mg/kg-diet (medium dose) and 100 mg/kg-diet (high dose) 2-AA for 14 and 28 days followed by analysis of the pancreas for broad gene expression changes. Results obtained from our study suggest most of the mRNA transcripts that were differentially expressed are involved in energy metabolism in the pancreas, protein digestion and some that play an active role in pancreatitis and pancreatic cancer. Some of these genes include: insulin, colipase pancreatic, carboxypeptidase, chymotrypsinogen B1 and chymotrypsin C (caldecrin). Quantitative PCR determination of fold changes in selected genes show similar trends to global expression determined via microarray analyses.
