Abstract

Regeneration of skeletal muscle relies on its resident stem cells, also known as satellite cells, which are normally quiescent. With aging, satellite cell quiescence is lost concomitant with a muscle regenerative decline. Here we demonstrate that autophagy sustains quiescence over time and that its failure with age drives senescence, which accounts for stem cell loss of function. Pharmacological and genetic reestablishment of autophagy restores homeostasis and regenerative functions in geriatric satellite cells, which has relevance for the elderly population.

  • The decreased activity of myogenic regulatory factors is due to dysregulated autophagy concerning inflammation and insulin resistance, also leading to a reduction in satellite cells.

    “The decreased activity of MRF is due to dysregulated autophagy concerning inflammation and IR, also leading to a reduction in satellite cells [92, 116, 126, 127].”

  • Satellite cells in obesity and overweight have a minor expression and activity of myogenic regulatory factors such as MyoD, Myf5, and Myf6.

    “Furthermore, satellite cells in obesity and overweight have a minor expression and activity of myogenic regulatory factors (MRFs) such as MyoD, Myf5, and Myf6.”

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.
