Mitochondrial DNA and respiratory chain function in spinal cords of ALS patients

Abstract

Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease characterized by selective motor neuron death. In order to address the question of a putative role of mitochondrial dysfunction in the pathogenesis of ALS, we studied the mitochondrial DNA (mtDNA) and mitochondrial respiratory chain enzyme activities in spinal cords of ALS patients and in control subjects without neuropathologic abnormalities. Using a ‘double PCR and digestion’ technique to estimate the levels of randomly distributed point mutations in two small regions of the mtDNA, we found significantly higher levels of mutant mtDNA in the spinal cord of ALS patients compared to controls. No large‐scale rearrangements were found, but the amount of mtDNA, measured by Southern blot, was significantly lower in the ALS samples. This reduction correlated well with a decrease of citrate synthase (CS) activity, a mitochondrial marker, as were the activities of respiratory chain complexes I + III, II + III, and IV, suggesting a loss of mitochondria in ALS spinal cords.

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.
