OPA1 Mutation and Late‐Onset Cardiomyopathy: Mitochondrial Dysfunction and mtDNA Instability
Open accessAbstract
Background: Mitochondrial fusion protein mutations are a cause of inherited neuropathies such as Charcot–Marie–Tooth disease and dominant optic atrophy. Previously we reported that the fusion protein optic atrophy 1 ( OPA 1) is decreased in heart failure. Methods and Results: We investigated cardiac function, mitochondrial function, and mtDNA stability in a mouse model of the disease with OPA 1 mutation. The homozygous mutation is embryonic lethal. Heterozygous OPA +/− mice exhibit reduced mtDNA copy number and decreased expression of nuclear antioxidant genes at 3 to 4 months. Although initial cardiac function was normal, at 12 months the OPA 1 +/− mouse hearts had decreased fractional shortening, cardiac output, and myocyte contraction. This coincided with the onset of blindness. In addition to small fragmented mitochondria, aged OPA 1 +/− mice had impaired cardiac mitochondrial function compared with wild‐type littermates. Conclusions: OPA 1 mutation leads to deficiency in antioxidant transcripts, increased reactive oxygen species, mitochondrial dysfunction, and late‐onset cardiomyopathy.

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.
