mortality/aging
extended life span ( J:331883 )
• mice exhibit an increased lifespan compared to wild-type mice
• mice are viable and fertile, show no increase in DNA damage, and appear to have normal DNA repair capacity

neoplasm
decreased liver tumor incidence ( J:331883 )
• mice exhibit decreased incidence of liver tumors, with no homozygotes showing liver tumors at 19-months-of age compared to 3 of 10 wild-type mice showing liver tumors at this time
