Parkinsonian Power Failure: Neuron Degeneration May Be Caused by a Cellular Energy System Breakdown

Posted: October 11, 2010 at 5:04 pm

In the past researchers have observed an association between poor mitochondrial function and Parkinson's disease, a neurodegenerative disorder of the central nervous system that impairs speech and motor functions and affects five million people worldwide. A new meta-analysis suggests that low expression levels of 10 related gene sets responsible for mitochondrial machinery play an important role in this disorder--all previously unlinked to Parkinson's. The study, published online today in Science Translational Medicine , further points to a master switch for these gene sets as a potential target of future therapies. [More]
