mortality/aging

premature death ( J:68981 )

• Background Sensitivity: ~30% of animals develop thymic lymphoma; incidence is higher than on pure 129/Sv background

increased skin papilloma incidence ( J:68981 )

• Background Sensitivity: about 40% of mice develop skin papillomas, with slightly higher incidence than on mixed 129 and C57BL/6 background

increased lung tumor incidence ( J:119477 )

• 100% of mice examined at 3-4 months of age have developed lung tumors
