Abstract

In humans, the strong statistical association between fitness and survival suggests a link between impaired oxygen metabolism and disease. We hypothesized that artificial selection of rats based on low and high intrinsic exercise capacity would yield models that also contrast for disease risk. After 11 generations, rats with low aerobic capacity scored high on cardiovascular risk factors that constitute the metabolic syndrome. The decrease in aerobic capacity was associated with decreases in the amounts of transcription factors required for mitochondrial biogenesis and in the amounts of oxidative enzymes in skeletal muscle. Impairment of mitochondrial function may link reduced fitness to cardiovascular and metabolic disease.

Claims other papers make about this one

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

  • Rat selection experiments support the idea that evolution could select for high aerobic capacity.

    “provided experimental evidence that natural selection for high aerobic capacity during evolution is a feasible concept (569).”

  • After 11 generations of selecting rats by running distance, the high-distance line had 58% greater aerobic capacity than the low-distance line.

    “Selection of rats on the basis of the longest or shortest running distances during a single exercise test resulted in selection of a 58% higher aerobic capacity in the high-distance line than the short-distance line over 11 generations.”

    From Lack of Exercise Is a Major Cause of Chronic Diseases (2012) · cites this paper as [569]

  • High-VO2max rats showed better cardiovascular and metabolic profiles: lower 24-hour blood pressure, improved acetylcholine-induced vasorelaxation, lower fasting glucose, less visceral fat, lower triglycerides, and more mitochondrial protein.

    “Rats with high VO2max had healthier cardiovascular systems (12% lower mean 24-hr blood pressures and 48% better acetylcholine-induced vasorelaxation), and healthier metabolic risk factors (16% less fasting plasma glucose, 39% less visceral adipose tissue, 63% lower plasma triglyceride levels, and greater mitochondrial protein concentrations).”

  • In rats bred for low aerobic capacity over multiple generations, expression of several OXPHOS genes is markedly reduced, even in the absence of obesity.

    “Similarly, in rats bred for low aerobic capacity over multiple generations, expression of several OXPHOS genes is markedly reduced, even in the absence of obesity (134).”

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.
