(Submitter supplied) To identify putative procarcinogenic gene changes associated with pancreatic acinar cell neoplasia in rats exposed to peroxisome proliferator activated receptor alpha agonists, we performed transcription profiling in the pancreas of rats fed diets containing the pancreatic carcinogen Wyeth 14,643 (Wy) at procarcinogenic (50ppm) and non-carcinogenic (20ppm) doses for 1, 7, 28 and 90 days. The effects of these treatments were compared to those of ammonium perfluorooctanoate (APFO) 300 ppm, an agent shown to induce pancreatic acinar cell adenomas in rats, and diethylhexylphthalate (DEHP) 12,000 ppm, an agent not shown to produce pancreatic acinar cell tumors.
