Abstract

ABSTRACT: Sarcopenia is an age-related disease that mainly involves decreases in muscle mass, muscle strength and muscle function. At the same time, the body fat content increases with aging, especially the visceral fat content. Adipose tissue is an endocrine organ that secretes biologically active factors called adipokines, which act on local and distant tissues. Studies have revealed that some adipokines exert regulatory effects on muscle, such as higher serum leptin levels causing a decrease in muscle function and adiponectin inhibits the transcriptional activity of Forkhead box O3 (FoxO3) by activating peroxisome proliferators-activated receptor-γ coactivator -1α (PGC-1α) and sensitizing cells to insulin, thereby repressing atrophy-related genes (atrogin-1 and muscle RING finger 1 [MuRF1]) to prevent the loss of muscle mass. Here, we describe the effects on muscle of adipokines produced by adipose tissue, such as leptin, adiponectin, resistin, mucin and lipocalin-2, and discuss the importance of these adipokines for understanding the development of sarcopenia.

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

  • Leptin released from adipose tissue functions as a metabolic gatekeeper of nutritional status, with low circulating levels commonly observed in patients with sarcopenia and in elderly individuals.

    “Leptin released from adipose tissue functions as a metabolic gatekeeper of nutritional status, with low circulating levels commonly observed in patients with sarcopenia and in elderly individuals”

    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 [97]

    The “Adipokines and Their Effects on Muscle > Leptin” section (page not specified) describes leptin as mainly produced by white fat, says serum levels may indicate long-term nutritional status, and reports lower levels in patients with sarcopenia. It links low leptin to reduced arm muscle area in elderly and infirm individuals, but does not say low circulating levels are commonly observed in elderly people generally. (LLM, conf=0.86)

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.
