Abstract

Sarcopenia is an aging-related disease with a significant reduction in mass and strength of skeletal muscle due to the imbalance between protein synthesis and protein degradation. The loss of skeletal muscle is an inevitable event during aging process, which can result in the significant impact on the quality of life, and also can increase the risk for other aging-associated diseases in the elderly. However, the underlying molecular mechanism of aging-related skeletal muscle loss is still poorly understood. Autophagy is a degradation pathway for the clearance of dysfunctional organelles and damaged macromolecules during aging process. Appropriate induction or accurate regulation of autophagic process and improved quality control of mitochondria through autophagy or other strategies are required for the maintenance of skeletal muscle mass. In this article, we have summarized the current understanding of autophagic pathways in sarcopenia, and discussed the functional status of autophagy and autophagy-associated quality control of mitochondria in the pathogenesis of sarcopenia. Moreover, this article will provide some theoretical references for the exploration of scientific and optimal intervention strategies such as exercise and caloric restriction for the prevention and treatment of sarcopenia through the regulation of autophagic pathways.

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Aging is associated with a decline in muscle mass (sarcopenia) and mitochondrial function, both of which are associated with dysregulated autophagy.

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.
