Abstract
Using the technique of alkaline elution analysis, the ability of 11 known or suspected pancreatic carcinogens to damage the DNA of pancreatic acinar cells when administered to rats and hamsters was examined. The two species respond differently to several agents. In selected instances, DNA damage was also assessed in cultured pancreatic acinar cells exposed in vitro to the agents. Comparisons of DNA damage produced in vivo with that produced in vitro gave useful information on the role of pancreatic metabolism in activating pancreatic carcinogens. Finally, information germane to the question of the cell of origin for pancreatic cancer was obtained.
