"Dimmer switches" that control the level of protein created from a given gene may regulate the development, function and, ultimately, the life span of cells that begin to vanish from the brain at the onset of Parkinson's disease."
"The finding, published in last week's Science, could offer a new therapeutic target for treating the neurodegenerative disorder—making it one of the first to tie these protein modulators, small snippets of RNA known as
microRNAs, to human disease"
