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...

Pancreatic Cancer Disrupts Circadian Patterns of Gene Expression in Cardiorespiratory Muscles.

BACKGROUND

Cancer cachexia, a debilitating syndrome characterized by muscle wasting, significantly impacts survival in gastrointestinal cancers like pancreatic cancer. Emerging evidence suggests a link between cancer cachexia and disrupted circadian rhythms in peripheral tissues, including locomotor muscles. However, circadian dysregulation in...

Aging of Skeletal Muscle: From Molecular Mechanisms to Therapeutic Interventions.

Skeletal muscle aging is a major cause of frailty, metabolic dysfunction, and loss of independence in later life, yet it cannot be explained by muscle mass loss alone. Recent single-cell, multi-omics, and translational studies show that aged muscle is shaped...

Integrating Leg-Press Strength and Nutritional Status Improves 16-Year Mortality Risk Stratification in General Older Adults.

BACKGROUND

Malnutrition and muscle weakness are critical prognostic factors for mortality in older adults. While indices like the Geriatric Nutritional Risk Index (GNRI) are well-established, the long-term prognostic value of integrating nutrition with muscle strength (MS) remains insufficiently established in community-dwelling...

UA-30 mitigates systemic aging and motor decline by inhibiting RalA signaling in naturally aged mice.

Aging, characterized by progressive physiological decline and systemic dysfunction, represents a major risk factor for age-related diseases such as sarcopenia, which involves fibrosis that disrupts muscle regeneration and function. Effective therapeutic strategies remain limited. Here we report UA-30, a novel...

Quantitative Muscle MRI Fat Fraction as a Biomarker of Disease Severity in Mitochondrial Myopathies.

BACKGROUND

Quantitative muscle MRI is increasingly used to assess structural muscle damage in inherited myopathies, but its application in primary mitochondrial myopathies (PMM) has not been systematically evaluated in large cohorts. Because PMM are clinically and genetically heterogeneous, objective imaging biomarkers...

Tumor-Secreted ADAMTSL4 Activates Latent TGFβ1 to Drive Cancer Cachexia.

UNLABELLED

Cancer cachexia is a devastating wasting syndrome with no approved therapies. In this study, we identify the tumor-derived glycoprotein ADAMTSL4 as a circulating factor associated with body weight loss in preclinical cachexia models and patients with colorectal and lung cancers....

Skeletal Muscle-Derived Extracellular Vesicles During Eccentric and Concentric Exercise Promote Muscle Regeneration After Injury.

BACKGROUND

Skeletal muscle injuries significantly impair mobility and function, yet effective therapeutic interventions remain limited. Both eccentric exercise (EE) and concentric exercise (CE) promote muscle repair, but the underlying mechanisms are not fully understood. Muscle-derived extracellular vesicles (mEVs) have emerged as...

NCOA4-Mediated Ferritinophagy Contributes to Iron Overload-Driven Ferroptosis of Senescent Myoblasts in Mice.

Sarcopenia is an age-related pathological syndrome characterized by progressive and generalized loss of skeletal muscle mass and function, with muscle atrophy representing its cardinal pathological hallmark. Ferroptosis, an iron-dependent regulated cell death, has been implicated in the pathogenesis of muscle...

Clinical Trial: Intensive Supervised Nutritional Therapy Versus Guideline-Based Nutritional Advice for Sarcopenia in Decompensated Cirrhosis-A Randomised Controlled Trial.

BACKGROUND

Sarcopenia is highly prevalent in decompensated cirrhosis and independently predicts adverse outcomes. Although nutritional therapy is guideline-recommended, evidence comparing specialist dietitian-supervised nutritional care with routine physician-delivered dietary advice remains limited.

AIM

To compare the efficacy of dietitian-supervised intensive nutritional therapy with physician-led...
