Skeletal muscle autophagy and its role in sarcopenia and organismal aging

Jiao, Jianqin, Demontis, Fabio·2017·Current Opinion in Pharmacology

Abstract

Sarcopenia, the loss of skeletal muscle mass and strength in the aged, is an important medical condition but its etiology is incompletely understood. Because autophagy promotes myofiber atrophy in the young, it was believed that autophagy inhibition would prevent sarcopenia. However, recent studies have revealed that autophagy actually maintains muscle mass and that its function declines during muscle aging. Consistently, boosting basal autophagy protects from age-related muscle dysfunction by promoting the selective degradation of misfolded proteins and dysfunctional organelles. Conversely, autophagy inhibition leads to loss of muscle strength and induces a maladaptive stress response responsible for myofiber atrophy in the aged. In addition to cell-autonomous effects, muscle autophagy and associated signaling pathways induce systemic responses in other aging tissues by modulating the expression and secretion of myokines. We propose that myokines and pharmacologic interventions that boost selective autophagy may prevent sarcopenia, delay systemic aging, and extend health span.

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.
