Abstract

Non‐Technical Summary Skeletal muscle has the capacity to modify its size in response to external cues such as mechanical load, neural activity, hormones, stress and nutritional status. Pathological muscle loss or ‘atrophy’ occurs as the result of a number of disparate conditions including ageing, immobilization, diabetes, cancer, sepsis and as a serious side effect of corticosteroid hormone treatment. Synthetic glucocorticoids are often used to treat inflammation; however, high doses and chronic use of these hormones can lead to the loss of skeletal muscle mass and weakness. We show that in mice with a deletion of the MuRF1 protein, but not the MAFbx protein, the loss of muscle mass is attenuated relative to normal mice following 14 days of glucocorticoid treatment. Knowledge of how the MuRF1 protein functions in skeletal muscle to regulate skeletal muscle mass could lead to the development of therapeutics to prevent muscle atrophy under various conditions including glucocorticoid treatment.

  • Inhibition of Atrogin-1 does not block denervation- and glucocorticoid-induced muscle loss and does not protect from aging sarcopenia.

    “Inhibition of Atrogin-1 does not block denervation- and glucocorticoids-induced muscle loss19,44 and does not protect from aging sarcopenia46.”
  • MuRF1 knockout mice are not protected from denervation-induced muscle loss at 7 days and only partially protected (around 30%) at 14 days; absence of MuRF1 does not protect from fasting or microgravity-induced atrophy, while muscle mass is spared following glucocorticoid treatment.

    “MuRF1 knockout mice are not protected from denervation-induced muscle loss at 7 days and only partially protected (around 30%) at 14 days39. Moreover, the absence of MuRF1 does not protect from fasting or microgravity induced atrophy, while muscle mass is spared following glucocorticoid treatment43,44.”
  • Animal models that lack MURF-1 expression are protected from atrophy.

    “Animal models that lack MURF-1 expression are protected from atrophy [71,72].”

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.
