Abstract
Prolonged treatment of Parkinson’s disease with levodopa leads to disabling side effects collectively referred to as ‘dyskinesias’. We hypothesized that bioenergetic function in the putamen might play a crucial role in the development of dyskinesias. To test this hypothesis we used post-mortem samples of the human putamen and applied real time-PCR approaches and gene expression microarrays. We found that mitochondrial DNA levels are decreased in patients who have developed dyskinesias, and mitochondrial DNA damage is concomitantly increased. These pathologies were not observed in Parkinson’s disease subjects without signs of dyskinesias. The group of nuclear mRNA transcripts coding for the proteins of the mitochondrial electron transfer chain was decreased in patients with dyskinesias to a larger extent than in patients who had not developed dyskinesias. To examine if dopamine fluctuations affect mitochondrial DNA levels in dopaminoceptive neurons, rat striatal neurons in culture were repeatedly exposed to levodopa, dopamine or their metabolites. Mitochondrial DNA levels were reduced after treatment with dopamine, but not after treatment with dopamine metabolites. Levodopa led to an increase in mitochondrial DNA levels. We conclude that mitochondrial susceptibility in the putamen plays a role in the development of dyskinesias.
