Popis: Pancreas cancer was induced in noninbred male Holtzman rats by the implantation of beeswax containing 7.12-dimethylbenz[a]anthracene (DMBA) into the "head" of the pancreas. The tumors that developed 4--6 months later were examined for their cyclic AMP and cyclic GMP levels. The lesions could be considered in one of two categories according to their cyclic nucleotide contents: lesions with significantly smaller amounts and those with greater amounts, compared with levels measured in the pancreas tissues of the control rats. The existence of two biochemically distinct groups may indicate different growth patterns of the DMBA-induced pancreatic neoplasia.
