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

behavior/neurological

behavior/neurological phenotype ( J:100975 )

N • coordination levels measured in rotorod tests are similar to wild-type, as is passive avoidance learning

N • 6-month old females show similar performance in spatial learning (Morris water maze)

abnormal spatial learning ( J:100975 )

• 6-month old males show significantly higher latency to locate platform compared to females

decreased vertical activity ( J:100975 )

nervous system

nervous system phenotype ( J:55835 )

N • upon 18 mg/kg kainic acid injection, significant loss of neocortical synaptophysin-positive presynaptic terminals and disruption of hippocampal axons are observed, similar to wild-type

neurodegeneration ( J:55835 , J:100975 )

• mice show significant loss of synaptophysin-positive presynaptic terminals and neuronal dendrites of the neocortex and hippocampus with age (7-9 months compared to 3-4 months) (J:55835)

• mice display similar degeneration to that observed in Apoe-deficient mice (J:100975)
