Deficient Cardiolipin Remodelling Alters Muscle Fibre Composition and Neuromuscular Connectivity in Barth Syndrome.
BACKGROUND
Barth syndrome (BTHS) is a rare X-linked mitochondrial disorder caused by mutations in the TAFAZZIN gene, which disrupts cardiolipin (CL) remodelling and mitochondrial function. While cardiac manifestations of BTHS are well characterized in male patients, the mechanisms underlying skeletal muscle...
Muscle Movement and Metabolism: Exercise and Skeletal Muscle as Mediators of Health. A Report from the 26th Annual Harvard Nutrition Obesity Symposium, 2025.
Skeletal muscle is a crucial facilitator of many of the effects of exercise on metabolic health. Intrinsic myocellular mechanisms, exercise-induced myokine secretion, and crosstalk between multiple organ systems contribute to the maintenance of energy homeostasis, cardiovascular health, strength, cognition, and...
Does Time Tick Faster in Cerebral Palsy? Accelerated Aging as a Framework for Skeletal Muscle Dysfunction.
Cerebral palsy (CP) is the most common cause of childhood-onset physical disability. It results from injury to the developing brain and is characterized by motor impairments, muscle weakness, and fatigue. CP is commonly associated with marked deficits in muscle mass...
Exploring the role of chemerin in skeletal muscle phenotype in those with kidney disease.
INTRODUCTION
People with chronic kidney disease (CKD) often experience poor muscle quality and elevations in skeletal muscle wasting and dysfunction, contributing to a reduced quality of life and an increased risk of morbidity and mortality. The adipokine chemerin is associated with...
A Novel Mouse Model to Identify Antigen-Specific Immune Responses in Pancreatic Cancer Cachexia.
BACKGROUND
Pancreatic Ductal Adenocarcinoma (PDAC) has a dismal five-year survival rate of 13% and is closely associated with cachexia. Cancer cachexia is a multifactorial syndrome characterized by irreversible wasting of skeletal muscles, fat loss and systemic inflammation. While cachexia is known...
Mitochondrial Permeability Transition in Skeletal Muscle Phenocopies Muscle Alterations seen in Cancer Cachexia and other Wasting Conditions.
BACKGROUND
Skeletal muscle in wasting conditions often exhibits a common set of phenotypes that include atrophy, mitochondrial respiratory dysfunction, and fragmentation of the acetylcholine receptor (AChR) cluster at the endplate. Mitochondria are frequently implicated in driving muscle pathology in these conditions,...
High Fat Diet and Obesity Each Increase Tumor Cell Proliferation and Muscle Wasting in Experimental Cancer Cachexia.
High fat diet (HFD) and associated obesity are suggested to predispose to cancer development, complicate cancer treatment, and accelerate mortality. Paradoxically, obese patients with lung cancer are reported to live longer, suggesting that high body mass is protective. Given that...
Asian Reference Values for Handgrip Strength, Gait Speed, Five-Times-Sit-to-Stand Test, Muscle Mass and Calf Circumference.
BACKGROUND
Handgrip strength, gait speed, Five-Times-Sit-to-Stand Test (FTSST) performance, skeletal muscle mass and calf circumference are important health outcomes, particularly useful for diagnosing sarcopenia. The aim of this study was to establish reference (normative) values for handgrip strength, gait speed, FTSST...
Skeletal muscle morphology and metabolism in heart failure compared to healthy controls: a systematic review and meta-analysis.
Background: Heart failure (HF) is characterised by altered skeletal muscle morphology. The aim of this systematic review and meta-analysis was to explore cross-sectional differences in muscle morphology and metabolism between patients with HF and healthy controls. Methods: A literature search...
Distinct Metabolomic Alterations Are Associated With Physical Function, Weight Loss, and Muscle Mass in Men With Cancer.
BACKGROUND
Treatments for cancer cachexia, defined as involuntary weight and muscle mass loss leading to significant functional impairment, remain unavailable partly due to insufficient improvement of clinically meaningful outcomes in current trials. By reflecting downstream effects of cellular function, metabolomics may...
Skeletal Muscle Mass Modifies the Prognostic Impact of LDL Cholesterol in Chronic Heart Failure.
BACKGROUND
Dyslipidaemia is among the major risk factors for atherosclerotic cardiovascular disease. Paradoxically, higher cholesterol levels are associated with better survival in heart failure (HF) of any aetiology. Because cholesterol is an integral component of skeletal muscle structure, one possible explanation...
Biomarkers.
BACKGROUND
Sarcopenia, an age-related loss of skeletal muscle strength, mass and function, is linked with dementia and Alzheimer's disease (AD). Current guideline-recommended tools to diagnose sarcopenia, such as appendicular skeletal muscle mass (ASM), calculated as the sum of lean muscle mass...
Glucagon Like Peptide-1 Receptor Agonists for Sarcopenia and Muscle Wasting Disorders: A Systematic Review of Efficacy and Mechanisms.
Muscle wasting disorders, including sarcopenia and skeletal muscle atrophy, are increasingly prevalent among older adults and those with metabolic comorbidities. Sarcopenia, a progressive age-associated condition, involves the decline in skeletal muscle mass, strength, and physical performance, affecting millions of people...
Skeletal Muscle HSF1 Alleviates Age-Associated Sarcopenia and Mitochondrial Function Decline via SIRT3-PGC1α Axis.
Age-related sarcopenia, characterized by progressive loss of skeletal muscle mass and strength, impacts metabolic health and quality of life in the elderly. Heat shock factor 1 (HSF1) is a transcription factor that orchestrates cellular responses to various stresses, while its...
Decorin Deficiency Promotes D-Galactose-Induced Skeletal Muscle Atrophy and Fibrosis by Regulating ITGB1/Akt/mTOR Signalling Pathway.
BACKGROUND
Primary sarcopenia is an age-associated disorder with progressive and generalised loss of skeletal muscle strength and mass. Skeletal muscle fibrosis is one of the significant pathological manifestations of age-associated sarcopenia. Decorin, a small dermatan-sulfate proteoglycan, participates in extracellular matrix assembly....
