• mice appear healthy and viable up to 18 months of age

cellular
abnormal DNA repair ( J:108782 )
• in absence of exogenous exposure to methylating agents, mice accumulate significant levels of 1-methyladenine in their genomes compared to wild-type or Alkbh3-deficient mice, detectable at 4 months and increasing by 8 months, due to inefficient DNA repair
• repair kinetics of 1-methyladenine lesions in DNA exposed to a methylating agent are much lower than in wild-type with only a small fraction of 1-methyladenine being repaired after 36 hours
