RETRACTED: Increased muscle PGC-1α expression protects from sarcopenia and metabolic disease during aging
Open accessAbstract
Aging is a major risk factor for metabolic disease and loss of skeletal muscle mass and strength, a condition known as sarcopenia. Both conditions present a major health burden to the elderly population. Here, we analyzed the effect of mildly increased PGC-1α expression in skeletal muscle during aging. We found that transgenic MCK-PGC-1α animals had preserved mitochondrial function, neuromuscular junctions, and muscle integrity during aging. Increased PGC-1α levels in skeletal muscle prevented muscle wasting by reducing apoptosis, autophagy, and proteasome degradation. The preservation of muscle integrity and function in MCK-PGC-1α animals resulted in significantly improved whole-body health; both the loss of bone mineral density and the increase of systemic chronic inflammation, observed during normal aging, were prevented. Importantly, MCK-PGC-1α animals also showed improved metabolic responses as evident by increased insulin sensitivity and insulin signaling in aged mice. Our results highlight the importance of intact muscle function and metabolism for whole-body homeostasis and indicate that modulation of PGC-1α levels in skeletal muscle presents an avenue for the prevention and treatment of a group of age-related disorders.

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.
