Abstract

The mitochondrial genome encodes 13 essential subunits of the respiratory chain and has remarkable genetics based on uniparental inheritance. Within human populations, the mitochondrial genome has a high rate of sequence divergence with multiple polymorphic variants and thus has played a major role in examining the evolutionary history of our species. In recent years it has also become apparent that pathogenic mitochondrial DNA (mtDNA) mutations play an important role in neurological and other diseases. Patients harbor many different mtDNA mutations, some of which are mtDNA mutations, some of which are inherited, but others that seem to be sporadic. It has also been suggested that mtDNA mutations play a role in aging and cancer, but the evidence for a causative role in these conditions is less clear. The accumulated data would suggest, however, that mtDNA mutations occur on a frequent basis. In this article we describe a new phenomenon: the accumulation of mtDNA mutations in human colonic crypt stem cells that result in a significant biochemical defect in their progeny. These studies have important consequences not only for understanding of the finding of mtDNA mutations in aging tissues and tumors, but also for determining the frequency of mtDNA mutations within a cell.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Several studies relate mtDNA defects to human stem cell aging.

    “several studies have related mtDNA defects to human stem cell aging100–102.”
  • Clonal expansion of mtDNA mutations has been described in numerous tissues from aged individuals, including skeletal muscle, substantia nigra neurons, heart and colonic crypts.

    “Clonal expansion of mtDNA mutations has been described in numerous tissues from aged individuals, such as skeletal muscle (Fayet et al., 2002; Muller-Hocker et al., 1993), substantia nigra neurons (Cottrell et al., 2001; Kraytsberg et al., 2006), heart (Muller-Hocker, 1989) and colonic crypts (Taylor et al., 2003).”

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.
