mortality/aging
• only 56.5% of female mice and 42.9% of male mice survive 9,10-dimethyl-1,2-benzanthracene (DMBA) exposure and remain tumor free

neoplasm

• no tumors were seen in 220 wild-type mice in the same colony
• exposure to 9,10-dimethyl-1,2-benzanthracene (DMBA) results in increased incidence of malignant lymphomas in heterozygous mice
• one individual with tumors of the pancreas
• no tumors were seen in 220 wild-type mice in the same colony

homeostasis/metabolism
• only 56.5% of female mice and 42.9% of male mice survive 9,10-dimethyl-1,2-benzanthracene (DMBA) exposure and remain tumor free
