Abstract

The mechanisms of delayed onset and cell death in Huntington's disease (HD) are unknown. One possibility is that a genetic defect in energy metabolism may result in slow excitotoxic neuronal death. Therefore, we examined the effects of age on striatal lesions produced by local administration of the mitochondrial toxin 3-nitropropionic acid in rats. In vivo chemical shift magnetic resonance imaging showed marked increases in striatal lactate concentrations that significantly correlated with increasing age. Histologic and neurochemical studies showed a striking age dependence of the lesions, with 4- and 12-month-old animals being much more susceptible than 1-month-old animals. Continuous systemic administration of low doses of 3-nitropropionic acid for 1 month resulted in striatal lesions showing growth-related changes in dendrites of striatal spiny neurons using the Golgi technique. These results show that a known mitochondrial toxin can produce selective axon-sparing striatal lesions showing both the age dependence and striatal spiny neuron dendritic changes that characterize HD.

  • The specific down-regulation of mitochondrial processes in aged striatum could help to explain previous observations demonstrating selective vulnerability to mitochondrial toxins and stresses in the striatum of old animals.

    “This specific down-regulation of mitochondrial processes in aged striatum could help to explain previous observations demonstrating selective vulnerability to mitochondrial toxins and stresses in the striatum of old animals (Brouillet et al., 1993; Patki et al., 2009).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
