mortality/aging

premature death ( J:72532 )

• 10% reduction in survival under hypoxia

• 40% reduction in survival under normotensive conditions

• all are dead by 23 months of age

cellular

oxidative stress ( J:72532 )

• measured as an increase in carbonylated protein

• sensitivity to oxidative stress increased in kidney, liver, and brain in particular

homeostasis/metabolism

abnormal enzyme/coenzyme level ( J:72532 )

• under conditions of hyperoxia thioredoxin reductase levels in the liver increase less than they do in controls (2X vs 3 X)

• thioredoxin reductase levels in the brain drop 40% under hyperoxia conditions whereas they are unaffected in controls

behavior/neurological

abnormal gait ( J:72532 )

• after 6 months of age, homozygous mice walk on the tips of their toes

♀	phenotype observed in females
♂	phenotype observed in males
N	normal phenotype

growth/size/body

decreased body weight ( J:196824 )

• in mice fed a diet with 0.10% or 0.15% methionine unlike single homozygotes

• however, mice fed a diet with 0.45% methionine exhibit normal growth

postnatal growth retardation ( J:196824 )

• in mice fed a diet with 0.10% or 0.15% methionine unlike single homozygotes

• however, mice fed a diet with 0.45% methionine exhibit normal growth
