Abstract

Loss of skeletal muscle mass and strength has recently become a hot research topic with the extension of life span and an increasingly sedentary lifestyle in modern society. Maintenance of skeletal muscle mass is considered an essential determinant of muscle strength and function. Myokines are cytokines synthesized and released by myocytes during muscular contractions. They are implicated in autocrine regulation of metabolism in the muscle as well as in the paracrine/endocrine regulation of other tissues and organs including adipose tissue, the liver, and the brain through their receptors. Till date, secretome analysis of human myocyte culture medium has revealed over 600 myokines. In this review article, we summarize our current knowledge of major identified and characterized myokines focusing on their biological activity and function, particularly in muscle mass and function.

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

  • Irisin released from muscle promotes browning of WAT, increasing non-shivering thermogenesis and energy availability during exercise.

    “Irisin released from muscle promotes the browning of WAT, thereby increasing non-shivering thermogenesis and energy availability during exercise”

    From Exercise-Induced Muscle–Fat Crosstalk: Molecular Mediators and Their Pharmacological Modulation for the Maintenance of Metabolic Flexibility in Aging (2025) · cites this paper as [88]

    The Irisin section (page unavailable) describes muscle FNDC5 driving brown fat-like development of white fat cells and increasing thermogenesis. It does not say that this increases energy availability during exercise, and it notes that an exercise-induced rise in circulating irisin is debated. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • Adiponectin secreted by adipose tissue enhances insulin sensitivity by activating AMPK signaling in skeletal muscle, promoting glucose uptake and increasing FA oxidation.

    “In parallel, adiponectin secreted by adipose tissue enhances insulin sensitivity by activating AMPK signaling in skeletal muscle, thereby promoting glucose uptake and increasing FA oxidation”

    From Exercise-Induced Muscle–Fat Crosstalk: Molecular Mediators and Their Pharmacological Modulation for the Maintenance of Metabolic Flexibility in Aging (2025) · cites this paper as [88]

    The Myonectin (CTRP15) section describes AMPK-mediated glucose uptake and fatty-acid oxidation in rat skeletal myocytes, but attributes those effects to myonectin, not adiponectin. Searches for adiponectin and the claimed adipose-tissue mechanism found no passage in our copy that addresses the claim. (LLM, conf=0.75)

    Experimental — accuracy not yet measured
  • Some myokines exert their effect within skeletal muscle itself and are involved in the regulation of muscle mass.

    “Some myokines exert their effect within skeletal muscle itself and are involved in the regulation of muscle mass (14) (Fig. 1).”

    From Muscle–Organ Crosstalk: The Emerging Roles of Myokines (2020) · cites this paper as [14]

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.
