Deubiquitinase YOD1 Inhibition Suppresses DEX- and Denervation-Induced Muscle Atrophy Through MAFbx Destabilization.

BACKGROUNDS

Muscle atrophy, characterized by progressive loss of muscle mass and function, is driven by muscle-specific E3 ligases MAFbx and MuRF1. While transcriptional regulation of E3 ligases is documented, the mechanism of their regulation by the ubiquitin-proteasome system remains unclear. This...

Sarcopenia promotes tumorigenesis by disrupting NOTCH-SDC2-regulated biogenesis of muscle-derived extracellular vesicles.

Sarcopenia is an age-related condition characterized by loss of skeletal muscle mass and strength and is associated with increased cancer incidence and mortality, yet how muscle decline promotes tumorigenesis remains unclear. Here, we show that skeletal muscle functions as an...

Simple clinical parameters to identify sarcopenia 1 year after gastrectomy for gastric cancer.

BACKGROUND

New-onset sarcopenia may develop after gastrectomy even in patients with normal muscle mass, but its detection in routine practice remains challenging. This study evaluated body composition changes after gastrectomy and identified clinical parameters associated with sarcopenia development.

METHODS

This retrospective study included...

Systemic Drivers and Molecular Mechanisms of Sarcopenia in Aetiology-Specific End-Stage Liver Disease.

BACKGROUND

Patients with end-stage liver disease (ESLD) often present with sarcopenia, defined as loss of skeletal muscle mass and quality, which is associated with reduced quality of life and increased mortality. However, the molecular mechanisms driving sarcopenia in ESLD are not...

Whole Genome Sequence Analysis of Weight Loss in 16 972 Participants With COPD Reveals Novel Risk Loci in DRAIC and RFX3.

BACKGROUND

Chronic obstructive pulmonary disease (COPD) is associated with musculoskeletal comorbidities, including cachexia. Weight loss (WL) is the major criterion for cachexia and increases risk for mortality in COPD. Risk factors for WL in COPD are incompletely understood. We performed this...

Cancer IDO1-Mediated Tryptophan-Kynurenine Metabolic Reprogramming to Drive Skeletal Muscle Atrophy and Cachexia Acceleration.

BACKGROUND

Cancer cachexia is a debilitating syndrome characterized by severe skeletal muscle wasting, which significantly impairs patient quality of life and survival. Indoleamine 2,3-dioxygenase 1 (IDO1), a key enzyme in tryptophan (Trp) metabolism, is often upregulated in cancers, but its specific...

A comprehensive review of cancer-induced cardiac wasting.

Cancer is frequently accompanied by cachexia, a systemic syndrome characterized by progressive loss of skeletal muscle mass, with or without loss of fat mass. Increasing evidence indicates that cancer can also induce cardiac muscle wasting, which is associated with structural...

Wearable Hybrid Strain-Myoelectric Sensing System for Machine-Learning-Assisted Sarcopenia Screening.

The early screening of sarcopenia represents a critical clinical need amid the accelerating global aging population. Current diagnostic methods, relying on bioelectrical impedance analysis (BIA), handgrip strength testing, and other clinical examinations, depend on costly medical equipment and struggle to...

Longitudinal Study of Frailty Phenotype in Relation to Chronic Kidney Disease Incidence.

BACKGROUND

The longitudinal relationship between frailty phenotype and CKD development, and the modifying role of genetic CKD risk in this association, remains unclear. Research on simple, noninvasive and quantifiable CKD prediction models incorporating frailty is limited.

METHODS

We analysed 214 502 CKD-free participants from...

Beyond Sarcopenia: A Systematic Review and Meta-Analysis on Muscle Outcomes After Bariatric Surgery.

BACKGROUND

Metabolic and bariatric surgery (MBS) produces substantial and sustained weight loss, but concerns remain about skeletal muscle loss and sarcopenia.

METHODS

We conducted a systematic review of longitudinal and cross-sectional studies evaluating changes in muscle quantity, strength, and physical performance following MBS...

Prevalence and risk factors of malnutrition among older adults with sarcopenia: a protocol of systematic review and meta-analysis.

BACKGROUND

Sarcopenia and malnutrition are closely interrelated geriatric syndromes that significantly contribute to frailty, functional decline, and increased mortality in older adults. Although a growing body of evidence suggests a strong association between these conditions, reported prevalence rates and associated risk...

Gut Microbiota-Linked Benefits of Low-Intensity Pulsed Ultrasound Rejuvenate the Ageing Muscle.

BACKGROUND

Ageing is an inevitable biological process that contributes to increased prevalence of age-associated diseases, including sarcopenia, defined by progressive loss of muscle mass, functional decline and a heightened risk of injury. Developing effective interventions remains a critical clinical priority. This...

UNC45B Reduction With Aging: A Myofiber-Intrinsic Promoting Factor for Sarcopenia.

Skeletal muscle mass and force decline with age, and the loss of muscle force precedes muscle atrophy. However, the underlying mechanisms remain unclear. Here, we investigated the role of the myosin co-chaperone, uncoordinated mutant number-45 myosin chaperone B (UNC45B), in...

Effects of Tai Chi combined with elastic band training on muscle and executive inhibitory function in older adults with sarcopenia: a randomized controlled trial based on fNIRS.

BACKGROUND

Resistance training benefits patients with sarcopenia. However, trials demonstrating the effectiveness of Tai Chi combined with elastic band training are sparse, and the underlying neurocognitive mechanisms remain unclear.

METHODS

Forty-nine older sarcopenia patients (≥60 years) were recruited and randomly assigned to three groups:...
