RIPK3 Inhibition Mitigates Denervated Muscle Atrophy via NOX4-Mediated Mitochondrial Restoration and Inflammation Suppression.

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...

Exercise Modalities to Preserve Muscle Mass and Bone Health After Metabolic Bariatric Surgery.

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...

Muscle Health and Prognosis in Patients With Cancer: New Insights.

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...

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...

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...

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...

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...

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...

Associations of Body Composition and Physical Function With Incident Diabetes in Older Adults: A 14-Year Prospective Cohort Study.

BACKGROUND

Longitudinal associations between age-related changes in body composition, physical performance and incident diabetes mellitus (DM) in older adults and the mediating role of branched-chain amino acids (BCAAs) remain understudied.

METHODS

This prospective cohort study included 4000 community-dwelling older adults at baseline. Longitudinal...

Dual Roles of Adipose Tissue in Skeletal Muscle Regeneration: Pro-Regenerative Versus Maladaptive.

Skeletal muscle accounts for approximately 40% of total body mass and is essential for locomotion, metabolic regulation and systemic homeostasis. Adipose tissue is increasingly recognized as an active component of the muscle's regenerative microenvironment. During muscle repair, adipose tissue contributes...

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,...

Exercise and Weekly Sirolimus (Rapamycin) in Older Adults: RAPA-EX-01 Randomised, Double-Blind, Placebo-Controlled Trial.

BACKGROUND

Preclinical models suggest alternating activation and inhibition of mechanistic target of rapamycin complex 1 (mTORC1) could enhance adaptation to exercise ('cycling hypothesis'). Whether this concept translates to older adults is unknown. This exploratory trial assessed whether once-weekly sirolimus (rapamycin) 6 mg...
