Abstract

Skeletal muscle adapts to decreases in activity and load by undergoing atrophy. To identify candidate molecular mediators of muscle atrophy, we performed transcript profiling. Although many genes were up-regulated in a single rat model of atrophy, only a small subset was universal in all atrophy models. Two of these genes encode ubiquitin ligases: Muscle RING Finger 1 ( MuRF1 ), and a gene we designate Muscle Atrophy F-box ( MAFbx ), the latter being a member of the SCF family of E3 ubiquitin ligases. Overexpression of MAFbx in myotubes produced atrophy, whereas mice deficient in either MAFbx or MuRF1 were found to be resistant to atrophy. These proteins are potential drug targets for the treatment of muscle atrophy.

  • MuRF1 and Atrogin-1 are key factors for ubiquitin-proteasome system-mediated protein degradation in muscle atrophy.

    “The E3 ligase muscle RING‐finger protein‐1 (MuRF1), encoded by Trim63, and the F‐Box protein Atrogin‐1, encoded by Fbxo32, are key factors for ubiquitin‐proteasome system‐mediated protein degradation in muscle atrophy.”

    From Sepsis induces interleukin 6, gp130/JAK2/STAT3, and muscle wasting (2022) · cites this paper as [7]

    The main text (page unavailable) calls MuRF1 and MAFbx critical regulators of muscle atrophy and describes their role as ubiquitin ligases that target proteins for proteasomal degradation. It qualifies their regulation of muscle-protein degradation as “most likely,” rather than establishing that mechanism definitively. The copy uses MAFbx and does not verify the Atrogin-1, Trim63, or Fbxo32 names in the citing sentence. (LLM, conf=0.83)

    Experimental — accuracy not yet measured
  • A study examining MuRF1 and Atrogin1 gene expression in several models of muscle atrophy has reported that their gene expression is up-regulated at different time points.

    “A study examining MuRF1 and Atrogin1 gene expression in several models of muscle atrophy has also reported that their gene expression is up-regulated at different time points (Bodine et al., 2001).”
  • 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.”
  • Atrogin-1/MAFbx and MuRF1 are the first ubiquitin ligases identified to play a role in muscle loss, are strongly upregulated in all catabolic conditions so far tested in animals, and are considered the master genes of muscle atrophy.

    “The first ubiquitin ligases that were identified to play a role in muscle loss were Atrogin-1/MAFbx and MuRF1. These two E3s are strongly upregulated in all the catabolic conditions so far tested in animals and are considered the master genes of muscle atrophy39.”
  • Genes encoding glycolysis and oxidative phosphorylation enzymes are coordinately suppressed in atrophying muscles during denervation, disuse, diabetes, cancer, fasting, and chronic kidney disease.

    “Genes encoding for glycolysis and oxidative phosphorylation enzymes are coordinately suppressed in atrophying muscles during denervation, disuse, diabetes, cancer, fasting, and chronic kidney disease [10, 11, 13, 20].”

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.
