Huntington's disease (HD) is a hereditary neurodegenerative disease that leads to striatal degeneration and a severe movement disorder. We used a transgenic mouse model of HD (the R6/2 line with approximately 150 glutamine repeats) to test a new therapy for this disease. We treated HD mice with metformin, a widely used anti-diabetes drug, in the drinking(More)
We have developed a simple and sensitive assay to quantify neuron-specific death in primary cell cultures that represents a significant improvement over more commonly used methods including manual cell counting and lactate dehydrogenase release. This new method selectively detects neuronal death by combining immunolabeling for a neuron-specific marker with(More)
Protein bound and free 3-nitrotyrosine (3NT) levels are elevated in neurodegenerative diseases and have been used as evidence for peroxynitrite generation. Intrastriatal injection of free 3NT causes dopaminergic neuron injury and represents a new mouse model of Parkinson's disease (PD). We are investigating the nature of free 3NT neurotoxicity. In primary(More)
