Abstract

Mitochondrial structural and functional integrity is maintained through the coordination of several processes (e.g., biogenesis, dynamics, mitophagy), collectively referred to as mitochondrial quality control (MQC). Dysfunctional MQC and inflammation are hallmarks of aging and are involved in the pathogenesis of muscle wasting disorders, including sarcopenia and cachexia. One of the consequences of failing MQC is the release of mitochondria-derived damage-associated molecular patterns (DAMPs). By virtue of their bacterial ancestry, these molecules can trigger an inflammatory response by interacting with receptors similar to those involved in pathogen-associated responses. Mitochondria-derived DAMPs, especially cell-free mitochondrial DNA, have recently been associated with conditions characterized by chronic inflammation, such as aging and degenerative diseases. Yet, their actual implication in the aging process and muscle wasting disorders is at an early stage of investigation. Here, we review the contribution of mitochondria-derived DAMPs to age-related systemic inflammation. We also provide arguments in support of the exploitation of such signaling pathways for the management of muscle wasting conditions.

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

  • Alterations in mPTP function contribute to the aging-related loss of muscle mass and function.

    “Alterations in mPTP function are undoubtedly contributing to the aging-related loss of muscle mass and function, since mPTP opening can trigger several atrophy-regulating pathways.”

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.
