Sarcopenia
Imaging-Derived Sarcopenic Obesity and Cardiovascular Outcomes: Insights Into Heart Failure Risk and Muscle Biology.
BACKGROUND
The prognostic value of obesity in cardiovascular disease is complex. Measures such as body mass index and waist-to-height ratio show differing associations with outcomes, especially in heart failure. Assessing sarcopenic obesity, the coexistence of excess fat and low muscle mass,...
Functional Outcomes and Quality of Life for Patients With Cachexia and Solid Tumour Cancers: Findings of a Systematic Literature Review.
BACKGROUND
Cachexia, a complex multifactorial syndrome characterized by loss of skeletal muscle mass, is common in cancer and impacts treatment response, quality of life (QoL) and survival. No effective therapy is currently available. This report summarizes findings from the literature on...
Comment on 'Asian Reference Values for Handgrip Strength, Gait Speed, Five-Times-Sit-to-Stand Test, Muscle Mass and Calf Circumference' by Grgic et al.-The Authors' Reply.
Deletion of Tgf-β1 From CD206 + M2 Macrophages Ameliorates Obesity-Induced Suppression of Myogenesis and AMPK Phosphorylation in Skeletal Muscle.
BACKGROUNDS
Obesity and diabetes impair the ability of the muscle to regenerate, repair and remodel, resulting in a gradual decrease in muscle mass and function. However, the underlying mechanisms and effective therapeutic strategies remain poorly understood. M2 macrophages within skeletal muscle...
3,3'-Diindolylmethane ameliorates muscle atrophy by modulating mitochondrial function and calcium homeostasis.
BACKGROUND
Sarcopenia is a chronic degenerative condition characterized by the progressive loss of muscle mass and function. Current therapeutic strategies exhibit limited therapeutic efficacy and present substantial challenges in ensuring sustained patient compliance. Although mitochondrial dysfunction is a confirmed biomarker of...
RNF10 Attenuates Age-Related Muscle Atrophy by Promoting p53 Degradation and Alleviating Oxidative Stress.
Evidence identifies proteostasis imbalance and oxidative stress serve as fundamental pathological hallmarks of muscular atrophy, yet ring finger protein 10 (RNF10), a novel E3 ubiquitin ligase, in age-related muscular atrophy remains poorly characterized. Employing a natural aging mouse model and...

Creatine/Creatinine Ratio and Myostatin as Biomarkers to Monitor Muscle Function in Duchenne Muscular Dystrophy Patients.
BACKGROUND
Duchenne Muscular Dystrophy (DMD) is characterized by progressive muscle wasting leading to early loss of motor function. Functional tests monitor disease progression and serve as clinical trial endpoints but are influenced by maturation in younger patients, high intra-patient variability and...
Hepatokines lipocalin 2 and osteopontin drive muscle atrophy in MASH.
A bidirectional relationship exists between metabolic dysfunction-associated steatotic liver disease (MASLD) and its progressive inflammatory form, metabolic dysfunction-associated steatohepatitis (MASH), and sarcopenia, with each worsening the prevalence and prognosis of the other. Hepatokines have recently been shown to affect skeletal...
Endocannabinoid system and skeletal muscle health: insights from cannabidiol.
The endocannabinoid (EC) system is a complex network comprising endogenous ligands, enzymes responsible for their synthesis and degradation, and various receptors (including CB1 and CB2). Present in many peripheral tissues, including skeletal muscle, EC system is now recognized to influence...
Lowered Abundance of Gut Bacteriophage Species Is Associated With Human Cancer Cachexia.
BACKGROUND
Cancer cachexia exemplifies a high medical need condition without effective treatment. Recent studies implicated bacterial gut microbiome alterations to cancer cachexia. Whether the gut bacteriophage profile, an important microbiome component for health and disease, is also related to cancer cachexia...
Sarcopenic obesity and dementia risk: Primary associations and landmark analyses of muscle strength and body composition trajectories.
BACKGROUND AND AIMS
Sarcopenic obesity (SO) has been proposed as a risk factor for cognitive impairment. Yet evidence is inconsistent and often limited by heterogeneous definitions and lack of longitudinal assessments. This study aimed to examine associations of SO with all-cause...
Muscle-Adipose Aging Dynamics and Inflammaging Patterns Across Ethnically Diverse Populations: Exploring Potential Roles of Lipolysis.
BACKGROUND
Muscle-adipose aging reflects interactions between body composition changes and chronic inflammatory processes, but age-related patterns in these measures across ethnically diverse populations remain incompletely described. Understanding population-specific patterns is crucial for developing tailored prevention and intervention strategies. We aimed to...
Positive allosteric modulator selective for adult muscle nicotinic acetylcholine receptor.
The muscle nicotinic acetylcholine receptor (AChR) is the key mediator of neuromuscular signal transmission and is essential for all voluntary movement in our body. In this study, we present DC-98-LC74, a positive allosteric modulator (PAM) for the adult skeletal muscle-type...
Novel Long-Acting Ghrelin Analogue PEP-064 Restores Energy Balance in C26 and Lewis Lung Carcinoma-Induced cachexia in Mice.
BACKGROUND
Cancer cachexia is a debilitating syndrome marked by involuntary weight loss resulting from reduced food intake and intricate metabolic reprogramming. Despite its high prevalence, cancer cachexia remains undertreated, with a lack of effective and approved pharmacotherapies. Ghrelin has emerged as...
