Mitochondrial Transplantation Preserves Regenerative Capacity of Denervated Skeletal Muscle by Disrupting a Ca 2+ Overload-Mitophagy-Ferroptosis Circuit.

BACKGROUND

Denervation-induced muscle atrophy progresses during the interval between nerve injury and reinnervation, and depletion of muscle satellite cells (MuSCs) contributes to impaired functional recovery. Although mitochondrial dysfunction and impaired quality control are implicated in muscle wasting, whether excessive mitochondrial turnover...

S100A9 Mediates Neuroblastoma-Associated Skeletal Muscle Atrophy via O-GlcNAcylation Repression and Activate Mitophagy Activation.

BACKGROUND

In patients with neuroblastoma (NB), skeletal muscle atrophy is a key factor linked to poor survival and decreased long-term quality of life. Nevertheless, there are still insufficient therapeutic methods that work, and the underlying mechanisms remain unclear. As persistent inflammation...

Neonatal overfeeding accelerates age-related sarcopenia and metabolic disorders through lifelong gut mucosa and microbiota programming in mice.

Early-life nutrition shapes lifelong health, yet the long-term consequences of childhood overnutrition, particularly on musculoskeletal aging, remain unclear. Here, we show that neonatal overfeeding acts as a developmental insult that accelerates age-related sarcopenia in both sexes. Using different mouse models,...

Remodelling of Skeletal Muscle During Iron Deficiency Anaemia and Recovery After Intravenous Iron Therapy.

BACKGROUND

The global prevalence of iron deficiency anaemia (IDA) is about 25% and even higher in women of reproductive age and children. IDA can impair skeletal muscle by disrupting oxygen utilization, energy production and contractile function. Haematological effects of intravenous (IV)...

NUB1 Regulates Muscle Atrophy in Lung Cancer Cachexia via NF-κB Signaling Pathway.

Cancer-associated cachexia (CAC) is a devastating multifactorial syndrome characterized by progressive skeletal muscle atrophy. Its mechanisms remain incompletely clarified, with limited effective therapeutic targets. NUB1, a negative regulator of ubiquitin-like proteins mediating protein degradation, has not been fully elucidated in...

Associations of Coexisting Metabolic Dysfunction-Associated Steatotic Liver Disease and Sarcopenia-Related Abnormalities With Adverse Clinical Outcomes Across Obesity States.

Metabolic dysfunction-associated steatotic liver disease (MASLD) is associated with adverse liver and non-liver outcomes, but the impact of coexisting sarcopenia-related abnormalities (e.g., low muscle strength [MS], muscle mass, and physical performance) remains unclear. In a prospective UK Biobank cohort (n...

Sulforaphane as a Therapeutic Target for Sarcopenia in Type 2 Diabetes: Mechanistic Insights and Translational Evidence.

Sulforaphane, a bioactive isothiocyanate abundant in cruciferous vegetables, has emerged as a potential multi-target therapeutic agent capable of mitigating these pathological processes. Here, using evidence from preclinical and clinical literature, we review the mechanistic and translational evidence linking sulforaphane with...

Aquaporin-4 Orchestrates Muscle Cell Differentiation and Satellite Cell Preservation: A Novel Target in Age-Related Muscle Decline.

BACKGROUND

Impaired muscle regeneration is a key contributor to age-related muscle decline, yet the molecular mechanisms linking muscle water homeostasis to regenerative failure remain incompletely understood. Aquaporin-4 (AQP4), a major skeletal muscle water channel, may have functions beyond water transport that...

Frailty Rather Than Sonographic Muscle Measurement Predicts Outcome in Liver Cirrhosis.

BACKGROUND

Sarcopenia and frailty are frequent in patients with liver cirrhosis and are associated with morbidity and mortality. Given the limitations of computed tomography (CT) for routine assessment of muscle loss and the need for practical bedside assessment, we aimed to...

Disruption of the Muscle-Brain Axis in Ageing: Role of Myokines in Sarcopenia and Neurodegeneration.

This narrative review analyzes how myokines act as key links in communication between skeletal muscle and the brain, focusing on the impact of aging on this axis. Although the current literature links defects in this signaling pathway to sarcopenia, neurodegeneration,...

Motor Cortex Hyperexcitability Is Coupled to Neuromuscular Dysfunction in Aged Mice.

Age-related weakness is strongly associated with disability and mortality in older adults. While muscle atrophy contributes to weakness, strength declines at a faster rate than muscle mass, implicating neural mechanisms such as changes at the spinal cord and neuromuscular junction....

Exploring the Impact of Urolithins A and B on Muscle Health: A Transcriptomic Analysis in Human Myotubes.

BACKGROUND

Urolithin A (UA) and urolithin B (UB) are gut microbiota-derived metabolites of ellagitannins reported to influence mitochondrial function, inflammation and muscle metabolism. Their comparative transcriptomic effects in human skeletal muscle cells remain undefined. We characterized UA- and UB-induced molecular responses...

A probiotic Bifidobacterium pseudocatenulatum converts hesperidin to bioactive hesperetin and improves metabolic dysfunction in aging mice.

Dietary flavonoids often require microbial metabolism to generate bioactive metabolites that influence host physiology. Hesperidin, a citrus flavanone glycoside, exhibits limited intestinal absorption and depends on gut microbial biotransformation to yield its active aglycone, hesperetin. Hesperetin activates CDGSH iron-sulfur domain...
