Modulation of apoptotic regulatory proteins and early activation of cytochrome C following systemic 3-nitropropionic acid administration.

The present study utilized the administration of the mitochondrial toxin, 3-nitropropionic acid (3-NP), to mimic the pathology associated with Huntington's disease (HD). 3-NP causes striatal cell degeneration via the inhibition of succinate dehydrogenase. There is growing evidence suggesting the role of apoptosis in 3-NP cell death.
