Abstract

A critical role of mitochondrial dysfunction and oxidative damage has been hypothesized in both aging and neurodegenerative diseases. Much of the evidence has been correlative, but recent evidence has shown that the accumulation of mitochondrial DNA mutations accelerates normal aging, leads to oxidative damage to nuclear DNA, and impairs gene transcription. Furthermore, overexpression of the antioxidant enzyme catalase in mitochondria increases murine life span. There is strong evidence from genetics and transgenic mouse models that mitochondrial dysfunction results in neurodegeneration and may contribute to the pathogenesis of Alzheimer's disease, Parkinson's disease, Huntington's disease, amyotrophic lateral sclerosis, hereditary spastic paraplegia, and cerebellar degenerations. Therapeutic approaches targeting mitochondrial dysfunction and oxidative damage in these diseases therefore have great promise. Ann Neurol 2005;58:495–505

  • Mitochondrial dysfunction plays a role in the pathophysiology of Parkinson's disease.

    “Much evidence suggests a role for mitochondrial dysfunction in the pathophysiology of PD, a common age-associated neurodegenerative disease characterized by progressive degeneration of the nigrostriatal dopamine (DA) pathway and presence of the intraneuronal protein inclusions (Lewy bodies)1-3.”

    From Mitochondrial Approaches for Neuroprotection (2008) · cites this paper as [1]

  • Impairment of mitochondrial complex-I activity has been observed in the substantia nigra, platelets, and skeletal muscle of PD patients, in some but not all studies.

    “An impairment of mitochondrial complex-I activity has been observed in the substantia nigra (SN), platelets, and skeletal muscle of PD patients 1, 9-13, in some but not in all studies14, 15.”

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.
