nervous system
N |
• despite decreased dopamine levels, no loss of dopaminergic neurons is seen at 18 months of age
• unlike in Parkinson's disease patients, Lewy bodies are not detected in the brainstem and substantia nigra
|
behavior/neurological
N |
• unlike in human patients with early stage sporadic Parkinson's disease, acoustic startle reflexes are not impaired
|
• decrease in total distance covered, horizontal activity, movement time, stereotypy count and center distance in an open field test beginning at 16 months of age
|
growth/size/body
• weigh up to 19% less than controls at 1 year of age
|
cellular
N |
• unlike in Drosophila pink1 null mutants, no defects in mitochondrial fission are detected
|
• decrease in ATP levels in dissociated neurons under basal conditions
• liver mitochondrial membrane potential shows a progressive age related reduction
|
• assays indicate age-related impairment in liver mitochondrial import reactions
|
• liver mitochondrial membrane potential shows a progressive age related reduction
|
• respiratory complex activity of purified liver mitochondria from 18 month old mice is significantly reduced compared to controls
|
endocrine/exocrine glands
N |
• unlike in human patients with early stage sporadic Parkinson's disease, increased sweating is not seen
|
homeostasis/metabolism
• decreased dopamine levels in the striatum at 9 and 22-24 months of age
|
mortality/aging
• mortality rate is reduced as compared to wild-type controls
• most mice live to 450 days, some live to greater than 600 days
