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

nervous system

decreased dopaminergic neuron number ( J:140326 )

• at 12 months of age, the number of dopamine transporter and VMAT2+ cells is decreased compared to in wild-type mice

neuron degeneration ( J:140326 )

• at 6 months of age, mice exhibit a reduction in the number of TH+ neurons in the substantia nigra pars compacta and locus ceruleus associated with apoptosis

• however, mice do not exhibit a change in hippocampal neurons at 24 months of age

cellular

abnormal redox activity ( J:140326 )

• at 18 and 24 months, mice exhibit a 30% reduction in mitochondrial complex I activity compared to in wild type mice

behavior/neurological

behavior/neurological phenotype ( J:140326 )

N • despite loss of dopaminergic neurons, mice exhibit normal behaviors

homeostasis/metabolism

decreased dopamine level ( J:140326 )

• by 24 months

increased dopamine level ( J:140326 )

• in young animals
