Abstract

Adiponectin (ApN) is a hormone abundantly secreted by adipocytes and it is known to be tightly linked to the metabolic syndrome. It promotes insulin-sensitizing, fat-burning, and anti-atherosclerotic actions, thereby effectively counteracting several metabolic disorders, including type 2 diabetes, obesity, and cardiovascular diseases. ApN is also known today to possess powerful anti-inflammatory/oxidative and pro-myogenic effects on skeletal muscles exposed to acute or chronic inflammation and injury, mainly through AdipoR1 (ApN specific muscle receptor) and AMP-activated protein kinase (AMPK) pathway, but also via T-cadherin. In this review, we will report all the beneficial and protective properties that ApN can exert, specifically on the skeletal muscle as a target tissue. We will highlight its effects and mechanisms of action, first in healthy skeletal muscle including exercised muscle, and second in diseased muscle from a variety of pathological conditions. In the end, we will go over some of AdipoRs agonists that can be easily produced and administered, and which can greatly mimic ApN. These interesting and newly identified molecules could pave the way towards future therapeutic approaches to potentially prevent or combat not only skeletal muscle disorders but also a plethora of other diseases with sterile inflammation or metabolic dysfunction.

TL;DR

Adiponectin (ApN) acts on skeletal muscle mainly through AdipoR1–AMPK signaling to improve insulin sensitivity, fatty-acid oxidation, inflammation/oxidative stress control, and regeneration. This review argues that ApN and its receptor agonists, especially AdipoRon, have therapeutic potential for dystrophic, sarcopenic, and metabolically diseased muscle.

Key findings

  • ApN circulates at ~μg/mL, at least 3 orders of magnitude higher than other hormones, as LMW trimer, MMW hexamer, and HMW 12–18 mers; HMW ApN elicits the most potent insulin-sensitizing effects.
  • In skeletal muscle, ApN activates AdipoR1–AMPK–PGC-1α/SIRT1, p38 MAPK/PPARα, and GLUT4 translocation, while repressing NF-κB and inflammasome pathways via PGC-1α, SIRT1, and miR-711.
  • Chronic exercise training increased circulating ApN and/or HMW ApN and muscle AdipoR1 in rodents (4–16 weeks) and humans (4–12 weeks), correlating with improved insulin sensitivity; ApN/AdipoR1 blockade diminished exercise benefits in aged SAMP10 mice.
  • In DMD models, ApN replenishment or oral AdipoRon for 2 months reduced inflammation/oxidative stress, improved myogenic factors and utrophin, and increased muscle force/endurance; ApN levels are decreased in mdx mice and human DMD patients.

Methods

  • Narrative review; no primary experiments reported.
  • Synthesizes in vivo rodent studies and in vitro human muscle cell studies, plus human exercise/observational data, across healthy muscle, exercise, diseased muscle (DMD, other dystrophies, sarcopenia), and ApN mimics.
  • Main analysis is qualitative synthesis of mechanisms and effects; no systematic search or meta-analysis is described.

Limitations

  • The paper states that interpreting exercise–ApN data is challenging because of differences in exercise type/program, participant characteristics and pathological context, inconsistent accounting for ApN oligomeric distribution, and difficulty attributing benefits to reduced fat mass versus exercise per se.
  • The paper states that ApN is not yet available for therapeutic use in humans; in vivo properties were studied only in rodents receiving/overexpressing the hormone or with ApN/AdipoR deficiency, although most mouse data were also confirmed in vitro in human muscle cells.
  • Evident from the text: as a narrative review, it does not report a systematic search, risk-of-bias assessment, or quantitative pooling, and conclusions rely on heterogeneous cited models and outcomes.

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?

  • Exercise-induced adiponectin reduces white fat synthesis to mitigate muscle atrophy, with mechanisms including enhanced insulin sensitivity, improved glucose uptake, promotion of myogenesis, inhibition of muscle protein degradation, and increased muscle hypertrophy.

    “Exercise-induced adiponectin also reduces white fat synthesis to mitigate muscle atrophy, with the primary mechanisms underlying this effect including enhanced insulin sensitivity, improved glucose uptake, promotion of myogenesis, inhibition of muscle protein degradation, and increased muscle hypertrophy [87,88].”
  • AdipoR1-deficient mice show reduced PGC-1α expression, mitochondrial biogenesis and function, and endurance training capacity.

    “AdipoR1-deficient mice show reduced PGC-1α expression, mitochondrial biogenesis and function, and endurance training capacity [87].”

Self-check

Percentages, sums and reported differences re-computed from the paper’s own numbers.

Each contradiction between two passages listed here was confirmed by an independent check.

  • Adiponectin mimic named GTFD in one section and GTDF in another

    Minor

    The sarcopenia section identifies the mimic as GTFD and directs readers to Section 6.2, which names it GTDF. The compound identifier is inconsistent.

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.

Claims read by deepseek-v4.1-flash under definition version 3 (extract-v3) on 2026-10-09.

Classified by jev-1.13-20260917 (gold-guideline-v0.2) on 2026-10-09.

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.
