BACKGROUND
Sepsis-induced myopathy (SIM) is a common and life-threatening complication, but its underlying mechanisms remain poorly understood. PACS2, a key resident protein at mitochondria-associated endoplasmic reticulum membranes (MAMs), regulates ER homeostasis under various pathological conditions. However, whether sepsis disrupts PACS2-dependent MAM...
BACKGROUND
Cancer cachexia (CC) is a highly debilitating syndrome characterized by loss of body and muscle weight affecting most advanced cancer patients. The receptor for advanced glycation end-products (RAGE) is expressed by several cell types and sustains the inflammatory response in...
BACKGROUND
Cachexia and sarcopenia are prevalent, inflammation-linked syndromes in chronic liver disease that worsen outcomes. To our knowledge, their coexistence in a single chronic liver disease cohort has not been systematically examined. In this study, we evaluated the prevalence, clinical features...
Skeletal muscle is a postmitotic tissue dependent on a complex and tightly regulated regeneration process involving numerous intracellular and extracellular factors, including myogenic regulatory factors (MRFs), cytokines and myokines. Quiescent satellite cells are activated by physiological stimuli, injury or other...
BACKGROUND
Peripheral nerve injury-induced muscle atrophy shares core pathophysiological features with systemic wasting disorders including cachexia and sarcopenia, yet early molecular triggers remain undefined. This study investigates the pathogenic role of receptor-interacting protein kinase 3 (RIPK3) in denervation atrophy.
METHODS
Sciatic denervation was...
BACKGROUND
Metabolic bariatric surgery (MBS) effectively reduces fat mass (FM), but how to best preserve muscle and bone mass after MBS is unknown.
OBJECTIVE
This study aimed to evaluate the effect of aerobic, resistance and combined exercise regimens on body composition, bone mineral...
BACKGROUND
Reduced muscle mass and impaired composition have each been independently associated with worse outcomes in patients with cancer. However, emerging evidence suggests that reduced muscle strength-namely, dynapenia-may be particularly important for prognostication, as it is easier to assess in clinical...
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...
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...
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...
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...
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...
