Total Skeletal Muscle PGC-1 Deficiency Uncouples Mitochondrial Derangements from Fiber Type Determination and Insulin Sensitivity
Open accessAbstract
Evidence is emerging that the PGC-1 coactivators serve a critical role in skeletal muscle metabolism, function, and disease. Mice with total PGC-1 deficiency in skeletal muscle (PGC-1α(-/-)β(f/f/MLC-Cre) mice) were generated and characterized. PGC-1α(-/-)β(f/f/MLC-Cre) mice exhibit a dramatic reduction in exercise performance compared to single PGC-1α- or PGC-1β-deficient mice and wild-type controls. The exercise phenotype of the PGC-1α(-/-)β(f/f/MLC-Cre) mice was associated with a marked diminution in muscle oxidative capacity, together with rapid depletion of muscle glycogen stores. In addition, the PGC-1α/β-deficient muscle exhibited mitochondrial structural derangements consistent with fusion/fission and biogenic defects. Surprisingly, the proportion of oxidative muscle fiber types (I, IIa) was not reduced in the PGC-1α(-/-)β(f/f/MLC-Cre) mice. Moreover, insulin sensitivity and glucose tolerance were not altered in the PGC-1α(-/-)β(f/f/MLC-Cre) mice. Taken together, we conclude that PGC-1 coactivators are necessary for the oxidative and mitochondrial programs of skeletal muscle but are dispensable for fundamental fiber type determination and insulin sensitivity.

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.
