Abstract

Myostatin (MSTN) is a well-reported negative regulator of muscle growth and a member of the transforming growth factor (TGF) family. MSTN has important functions in skeletal muscle (SM), and its crucial involvement in several disorders has made it an important therapeutic target. Several strategies based on the use of natural compounds to inhibitory peptides are being used to inhibit the activity of MSTN. This review delivers an overview of the current state of knowledge about SM and myogenesis with particular emphasis on the structural characteristics and regulatory functions of MSTN during myogenesis and its involvements in various muscle related disorders. In addition, we review the diverse approaches used to inhibit the activity of MSTN, especially in silico approaches to the screening of natural compounds and the design of novel short peptides derived from proteins that typically interact with MSTN.

  • In human skeletal muscle, resistance training primarily activates mechanical stress-sensitive pathways; tension sensed by integrins and focal adhesion kinase leads to JNK phosphorylation, and JNK phosphorylates Smad2/3 and inhibits nuclear translocation, downregulating MSTN expression.

    “In human skeletal muscle, resistance training primarily activates mechanical stress-sensitive pathways. The tension generated during muscle contraction is sensed by integrins and focal adhesion kinase (FAK), leading to JNK phosphorylation. JNK directly phosphorylates Smad2/3 and inhibits their nuclear translocation, thereby downregulating MSTN expression [55].”

  • The molecular mechanisms underlying resistance training-induced myostatin suppression involve inhibition of the classical SMAD pathway and modulation of non-SMAD pathways such as MAPK/ERK, p38, JNK, and Akt phosphorylation.

    “The molecular mechanisms underlying resistance training-induced MSTN suppression involve multiple signaling pathways, including inhibition of the classical SMAD pathway and modulation of non-SMAD pathways such as MAPK/ERK, p38, JNK, and Akt phosphorylation [55].”

    From Exercise-Induced Myokines in Obesity-Related Metabolic Disorders and Cardiovascular Protection: A Narrative Review (2026) · cites this paper as [55]

    The Signaling Pathways section describes Smad and non-Smad myostatin signaling, including JNK/ERK, p38 MAPK, and Akt phosphorylation. The Smad-Mediated Pathways subsection also associates inhibition of myostatin–Smad signaling with muscle hypertrophy. These passages do not establish that resistance training suppresses myostatin through those pathways. (LLM, conf=0.87)

    Experimental — accuracy not yet measured
  • Myostatin exerts its effects by binding to activin receptor type IIB, leading to phosphorylation of SMAD2/3 and subsequent inhibition of myogenic gene transcription.

    “MSTN exerts its effects by binding to activin receptor type IIB (ActRIIB), leading to phosphorylation of SMAD2/3 and subsequent inhibition of myogenic gene transcription [55].”

    From Exercise-Induced Myokines in Obesity-Related Metabolic Disorders and Cardiovascular Protection: A Narrative Review (2026) · cites this paper as [55]

    The Signaling Pathways figure says MSTN binds the ACVRIIB–ALK4/5 complex and triggers Smad2/3 phosphorylation. The Smad-Mediated Pathways section says this signaling inhibits myoblast differentiation, but the copy does not specifically say that phosphorylated Smad2/3 inhibits myogenic gene transcription; it describes transcriptional alterations more generally. (LLM, conf=0.82)

    Experimental — accuracy not yet measured
  • Myostatin is also expressed in adipose tissue and has been implicated in metabolic regulation and cardiovascular pathology.

    “Beyond its canonical role in muscle, MSTN is also expressed in adipose tissue and has been implicated in metabolic regulation and cardiovascular pathology.”

    From Exercise-Induced Myokines in Obesity-Related Metabolic Disorders and Cardiovascular Protection: A Narrative Review (2026) · cites this paper as [55]

    The ‘Diabetes and Obesity’ section implicates MSTN in metabolic regulation, including insulin sensitivity and obesity. The copy does not establish that MSTN itself is expressed in adipose tissue: the ‘MSTN Receptor Proteins’ section says its receptor is distributed there, while a reference title mentions adipose-tissue gene expression. Its cardiovascular references concern myokines generally or an inhibitor, not a role for MSTN in cardiovascular pathology. No page numbers are provided in the copy. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • Myostatin levels rise with increasing obesity and correlate with insulin resistance, whereas Metrnl levels may progressively decrease as obesity worsens.

    “Closely related is obesity severity: myostatin levels have been shown to rise with increasing obesity and to correlate with insulin resistance [55], whereas Metrnl levels may progressively decrease as obesity worsens [68].”

    From Exercise-Induced Myokines in Obesity-Related Metabolic Disorders and Cardiovascular Protection: A Narrative Review (2026) · cites this paper as [55]

    The “Diabetes and Obesity” section (page unavailable) reports higher myostatin secretion in obese insulin-resistant subjects, high expression in morbidly obese patients, and an inverse relationship between myostatin expression and insulin sensitivity. It does not establish that myostatin levels rise progressively as obesity severity increases. The Metrnl clause is attributed to a different citation and is not part of this verdict. (LLM, conf=0.84)

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.
