Abstract

Aging-associated muscle insulin resistance has been hypothesized to be due to decreased mitochondrial function, secondary to cumulative free radical damage, leading to increased intramyocellular lipid content. To directly test this hypothesis, we examined both in vivo and in vitro mitochondrial function, intramyocellular lipid content, and insulin action in lean healthy mice with targeted overexpression of the human catalase gene to mitochondria (MCAT mice). Here, we show that MCAT mice are protected from age-induced decrease in muscle mitochondrial function (∼30%), energy metabolism (∼7%), and lipid-induced muscle insulin resistance. This protection from age-induced reduction in mitochondrial function was associated with reduced mitochondrial oxidative damage, preserved mitochondrial respiration and muscle ATP synthesis, and AMP-activated protein kinase-induced mitochondrial biogenesis. Taken together, these data suggest that the preserved mitochondrial function maintained by reducing mitochondrial oxidative damage may prevent age-associated whole-body energy imbalance and muscle insulin resistance.

  • Dysfunctional mitochondria accumulate with age, most clearly in tissues composed mainly of post-mitotic cells.

    “Dysfunctional mitochondria accumulate with age, best documented in tissues comprised largely of post-mitotic cells”

    From Mitochondrial Dysfunction Induces Senescence with a Distinct Secretory Phenotype (2016) · cites this paper as Lee et al., 2010

    The Results (page unavailable) report age-associated reductions in muscle mitochondrial function in old mice, supporting the claim's general point about aging and dysfunction. They do not establish that dysfunctional mitochondria accumulate or that the pattern is best documented in largely post-mitotic tissues; the reported mitochondrial density in soleus muscle decreased with age.

  • Genetic or pharmacological manipulations that lower mitochondrial ROS production preserve insulin action in lipid-treated myotubes and in mice fed a high-fat diet.

    “genetic or pharmacological manipulations that lowered mitochondrial ROS production preserved insulin action in lipid-treated myotubes (Hoehn et al., 2009) and in mice fed a high fat diet (Anderson et al., 2009; Hoehn et al., 2009; Lee et al., 2010).”

    From Lipid-Induced Mitochondrial Stress and Insulin Action in Muscle (2012) · cites this paper as Lee et al., 2010

  • Aged wild type mice develop muscle insulin resistance associated with increased muscle lipid (TAG/DAG) content (but no change in ceramide) and reduced muscle mitochondrial function.

    “Like humans, it was found that aged wild type mice develop muscle insulin resistance, which was associated with increased muscle lipid (TAG/DAG) content (but no change in muscle ceramide content) and reduced muscle mitochondrial function.”
  • Effects of aging were abrogated in mice with targeted overexpression of catalase to mitochondria.

    “Interestingly, all these effects of aging were abrogated in mice with targeted overexpression of catalase to the mitochondria.”
  • There is substantial evidence of increased ROS production and oxidative stress-induced damage to mtDNA and ETC complexes in aged rodents and non-human primates, as well as in human vastus lateralis muscle.

    “there is substantial evidence showing increased ROS production and associated oxidative stress-induced damage to mitochondrial DNA (mtDNA) and ETC complexes in aged rodents and non-human primates (Figueiredo, Powers, Ferreira, Appell, and Duarte 2009;Lee, Choi, Birkenfeld, Alves, Jornayvaz, Jurczak, Zhang, Woo, Shadel, and Ladiges 2010;Lee, Wang, and Fanburg 1998;WANAGAT, CAO, PATHARE, and AIKEN 2”

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.
