Ageing-associated 5 kb deletion in human liver mitochondrial DNA

Abstract

Using PCR technique and restriction mapping, we analyzed liver mitochondrial DNA (mtDNA) of 2 stillborn babies and 55 Chinese subjects from 27 to 86 years old and blood cell mtDNA from 20 subjects of various ages. An ageing-associated 4,977-bp deletion was detected between nucleotide position 8,469 and 13,447 (or between 8,482 and 13,460) in the liver mtDNA of older subjects. In the region containing the junction fragment, we observed a 13 bp repeat "ACCTCCCTCACCA". Moreover, the incidence of the deleted mtDNA of each of the study subjects was found to increase with age. The deletion was found in 5 out of 8 patients of the 31-40 age group and 9 out of 11 patients of the 41-50 age group, and in all the patients over 50 years old. The deletion was not observed in either the mtDNA of the liver of the stillbirth or the blood cells of subjects of all the age groups. These results support our previous contention that liver mitochondrial respiratory functions decline with age and the hypothesis that continuous accumulation of mitochondrial DNA mutation is an important contributor to ageing process.

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

  • Accumulations of mtDNA damage in the form of point mutations, deletions and depletions are correlated with aging and age-related diseases as observed in human skeletal muscle, liver, brain, heart, skin fibroblasts and colonic crypt stem cells.

    “Accumulations of mtDNA damage in the form of point mutations, deletions and depletions are correlated with aging and age-related diseases as observed in human skeletal muscle (Bua et al., 2006; Fayet et al., 2002), liver (Yen et al., 1991), brain (Corral-Debrinski et al., 1992a; Corral-Debrinski et al., 1994; Lin et al., 2002), heart (Corral-Debrinski et al., 1992b; Cortopassi and Arnheim, 1990),”

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.
