Abstract

Methionine restriction increases life span in rats and mice and reduces age-related accretion of adipose tissue in Fischer 344 rats. Recent reports have shown that adipose tissue mitochondrial content and function are associated with adiposity; therefore, the expression of genes involved in mitochondrial biogenesis and oxidative capacity was examined in white adipose tissue, liver, and skeletal muscle from Fischer 344 rats fed control (0.86% methionine) or methionine-restricted (0.17% methionine) diets for 3 months. Methionine restriction induced transcriptional changes of peroxisome proliferator-activated receptors, peroxisome proliferator-activated receptor coactivators 1alpha and 1beta, and some of their known target genes in all of these tissues. In addition, tissue-specific responses were elicited at the protein level. In inguinal adipose tissue, methionine restriction increased protein levels of peroxisome proliferator-activated receptor and peroxisome proliferator-activated receptor coactivator target genes. It also induced mitochondrial DNA copy number, suggesting mitochondrial biogenesis and corresponding with the up-regulation of citrate synthase activity. In contrast, methionine restriction induced changes in mitochondrial glycerol-3-phosphate dehydrogenase activity and stearoyl-coenzyme A desaturase 1 protein levels only in liver and uncoupling protein 3 and cytochrome c oxidase subunit IV protein levels only in skeletal muscle. No increase in mitochondrial DNA copy number was observed in liver and skeletal muscle despite an increase in mitochondrial citrate synthase activity. The results indicate that adiposity resistance in methionine-restricted rats is associated with mitochondrial biogenesis in inguinal adipose tissue and increased mitochondrial aerobic capacity in liver and skeletal muscle.

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.
