Aminooxyacetic acid striatal lesions attenuated by 1,3-butanediol and coenzyme Q10

Abstract

We previously showed that intrastriatal administration of aminooxyacetic acid (AOAA) produces striatal lesions by a secondary excitotoxic mechanism associated with impairment of oxidative phosphorylation. In the present study, we show that and the specific complex I inhibitor rotenone produces a similar neurochemical profile in the striatum, consistent with an effect of AOAA on energy metabolism. Lesions produced by AOAA were dose-dependently blocked by MK-801, with complete protection against GABA and substance P depletions at a dose of 3 mg/kg. AOAA lesions were significantly attenuated by pretreatment with either 1,3-butanediol or coenzyme Q10, two compounds which are thought to improve energy metabolism. These results provide further evidence that AOAA produces striatal excitotoxic lesions as a consequence of energy depletion and they suggest therapeutic strategies which may be useful in neurodegenerative diseases.

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.
