Metabolomics Reveals Multiple Metabolic Alterations and Biomarkers of Disease Severity in Facioscapulohumeral Muscle Dystrophy.

BACKGROUND

Facioscapulohumeral muscular dystrophy type 1 (FSHD1) is one of the most common adult-onset myopathies and is causally associated with a contraction of the D4Z4 macrosatellite repeat array on chromosome 4. It presents with a variable pattern of progressive muscle weakness...

Molecular targets for the treatment of sarcopenia: a geroscience approach.

INTRODUCTION

Sarcopenia is increasingly recognized as a multisystem geroscience condition. The limited efficacy of first-generation anabolic therapies has challenged the paradigm that increasing muscle mass is sufficient to restore physical performance, highlighting the need for therapeutic strategies that address the biological...

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...

Adaptive Mitochondrial Specialization in Lung Adenocarcinoma: Redox Homeostasis, Hypoxia Adaptation, and Therapeutic Resistance.

Lung adenocarcinoma (LUAD) exhibits metabolic flexibility that transcends the classical interpretation of the Warburg effect. This review proposes the concept of "adaptive mitochondrial specialization (AMS)", an integrative framework in which mitochondria undergo coordinated, context-dependent remodeling of bioenergetic metabolism, redox homeostasis,...

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...

Imeglimin Attenuates Skeletal Muscle Atrophy in Mouse Models of Obesity and Ageing.

BACKGROUND

Sarcopenia is a major contributor to frailty and mortality in ageing and obesity and is tightly linked to metabolic dysfunction. Imeglimin is a first-in-class oral hypoglycaemic agent targeting mitochondrial function; however, despite the central role of mitochondria in skeletal muscle...

Autophagy in cancer cachexia: From mechanisms to therapeutic opportunities.

Cancer cachexia is a multifactorial syndrome characterized by body weight loss, muscle wasting, and systemic metabolic alterations, significantly contributing to patient morbidity and mortality. A key feature of cachexia is the excessive degradation of muscle proteins and mitochondria, largely mediated...

Ghrelin Receptor Deletion or Pharmacological Inhibition Improves Muscle Function in Aging Male Mice.

Sarcopenia is characterized by age-related declines in muscle strength and mass, along with impaired physical function. It remains an unmet medical need, and there are no pharmacological interventions approved for this indication. The activation of growth hormone secretagogue receptor (GHSR)-1a,...

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...

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,...

Mitochondrial Transporter ABCB10 Protects Against Doxorubicin-Induced Respiratory Muscle Dysfunction Independent of Changes to Diaphragm Accumulation.

BACKGROUND

Doxorubicin (DOX) is a highly effective chemotherapeutic agent whose use can cause respiratory toxicity, increasing patient fatigue and negatively impacting quality of life and survival. These adverse effects occur due to diaphragm muscle mitochondrial accumulation of DOX, where it causes...
