Activation of the Lactate Receptor GPR81 Ameliorates Senescence Hallmarks and Improves Muscle Function in Cellular and Progeroid Models of Aging

open access: yesAging Cell, Volume 25, Issue 8, August 2026.
Skeletal muscle aging is associated with a decrease in expression of the lactate receptor GPR81. Treating senescent myoblasts in vitro and progeric mice in vivo with GPR81 agonist decreases intramyocellular lipid accumulation and reverses hallmarks of aging. ABSTRACT Skeletal muscle aging is associated with increased lipid accumulation, or myosteatosis,

Notch Signaling Rescues Loss of Satellite Cells Lacking Pax7 and Promotes Brown Adipogenic Differentiation

open access: yesCell Reports, 2016
Pax7 is a nodal transcription factor that is essential for regulating the maintenance, expansion, and myogenic identity of satellite cells during both neonatal and adult myogenesis.

Diosgenin Alleviates Age‐Related Sarcopenia by Promoting Satellite Cell Proliferation and Myogenic Differentiation via Activation of the SIRT1/PGC‐1α Signaling Pathway

open access: yesAging Cell, Volume 25, Issue 8, August 2026.
As a critical bioactive component of Polygonatum sibiricum, diosgenin improves age‐related declines in skeletal muscle mass and function by activating the SIRT1/PGC‐1α pathway, upregulating the expression of the myokine METRNL and IGF‐1, and promoting satellite cell proliferation and myogenic differentiation.

Differential Myopathic and Transcriptomic Changes in Soleus and Gastrocnemius Muscles in a Novel Chronic Hindlimb Ischemia Rat Model Induced by Endovascular Catheter Occlusion

open access: yesActa Physiologica, Volume 242, Issue 8, August 2026.
ABSTRACT Peripheral artery disease (PAD) is a progressive atherothrombotic disorder affecting more than 230 million people worldwide. Conventional animal models of chronic hindlimb ischemia (HLI) are highly invasive, technically challenging, fail to account for anatomical variation, and may not accurately recapitulate progressive PAD pathophysiology ...

Myonuclear Dynamics After Skeletal Muscle Surgical Injury

open access: yesThe FASEB Journal, Volume 40, Issue 14, 31 July 2026.
Using a recombination‐independent doxycycline inducible model of timed nonsatellite cell‐derived myonuclear labeling in adult skeletal muscle, we show that resident myonuclei move and become displaced within intact muscle fibers after muscle surgical injury.

A Myocyte‐Enriched Long Non‐Coding RNA NRMLncR Enhances Myogenesis in Mouse

open access: yesThe FASEB Journal, Volume 40, Issue 13, 15 July 2026.
We identified a novel myocyte‐enriched, Notch‐repressed myogenic lncRNA, NRMLncR, that is induced by myogenic regulatory factors (MRFs) during myogenic progression in mouse. NRMLncR localizes to cytoplasmic and nuclear compartments, associates with the RNA‐binding protein CUGBP Elav‐like family member 1 (CELF1), and is linked to neighboring gene Tbx1 ...

MLL1 is required for PAX7 expression and satellite cell self-renewal in mice

open access: yesNature Communications, 2019
PAX7 transcription factor specifies the myogenic identity of muscle stem cells and acts as a nodal factor by stimulating proliferation while inhibiting differentiation.

Dynamics of pax7 expression during development, muscle regeneration, and in vitro differentiation of satellite cells in rainbow trout (Oncorhynchus mykiss).

open access: yesPLoS ONE
Essential for muscle fiber formation and hypertrophy, muscle stem cells, also called satellite cells, reside beneath the basal lamina of the muscle fiber.

Comparative expression analysis of Pax3 and Pax7 during mouse myogenesis

open access: yesThe International Journal of Developmental Biology, 2006
Pax3 and Pax7 are closely related transcription factors involved in the commitment of myogenic precursors in the developing trunk. However, it is not yet clear whether these genes are required for myogenic cell specification in the head and for post-somitic myogensis per se.

Expression patterns of FSHD-causing DUX4 and myogenic transcription factors PAX3 and PAX7 are spatially distinct in differentiating human stem cell cultures

open access: yesSkeletal Muscle, 2017
Background Facioscapulohumeral muscular dystrophy (FSHD) is most commonly inherited in an autosomal dominant pattern and caused by the abnormal expression of DUX4 in skeletal muscle.
