Negative Impact of p21-Activated Kinase 4-Mediated AMP-Activated Protein Kinase Inhibition on Sarcopenia in Mice and Humans.
We recently identified that AMP-activated protein kinase (AMPK) α2 phosphorylation at S491 is mediated by p21-activated kinase 4 (PAK4), leading to muscular and systemic insulin resistance. This study examined how muscle PAK4 deletion affects atrophy in male mice and its...
Comment on 'Adherence to Physical Activity and Incident Mobility Disability in Older Adults With Mobility Limitations' by Alvarez-Bustos et al.: The Authors' Reply.
Air pollution exacerbates cardiovascular-kidney-metabolic syndrome and sarcopenia comorbidity via shared genetic-epigenetic mechanisms: A multi-omics and Mendelian Randomization study.
BACKGROUND
Ambient air pollution aggravates cardiovascular-kidney-metabolic (CKM) disorders and sarcopenia, yet the shared genetic and epigenetic mechanisms that underlie their frequent co-occurrence remain poorly understood.
METHODS
We integrated genome-wide association study (GWAS) data for CKM components (cardiovascular disease [CVD], chronic kidney disease [CKD],...
Peak Expiratory Flow and Its Trajectories Associated With Frailty in Older Adults: A Prospective Cohort Study.
BACKGROUND
Current evidence indicates an association between peak expiratory flow (PEF) and frailty in older adults, yet critical gaps persist regarding: the longitudinal dynamics of PEF trajectories, their temporal relationships with frailty progression and underlying biological mechanisms. This study aimed to...
Statin Use Is Associated With a Decline in Muscle Function and Mass Over Time, Irrespective of Statin Pharmacogenomic Score.
BACKGROUND
Statins are cholesterol-lowering drugs widely prescribed for preventing cardiovascular diseases. They may cause adverse effects on skeletal muscle, but it remains unclear whether they affect muscle function and mass. We aimed to evaluate the association between statin use and muscle...
The Monocrotaline Model of Hypertension Leads to Cachexia in Male but Not Female Mice.
BACKGROUND
The monocrotaline (MCT) model of cardiac cachexia is a pharmaceutical approach to pulmonary hypertension that has been used to study heart failure and muscle wasting in rodents; however, little is known of how this pyrrolizidine alkaloid leads to peripheral changes...
Mitochondrial stress bridge: Could muscle-derived extracellular vesicles be the missing link between sarcopenia, insulin resistance, and chemotherapy-induced cardiotoxicity?
Sarcopenia is currently considered a systemic condition that goes beyond muscle atrophy to include multifunctional metabolic and cardiovascular dysfunction. The mediators between skeletal muscle loss and entire body insulin resistance and increased vulnerability to cardiotoxicity caused by chemotherapy are not...
Exploring the potential of ginseng-derived compounds in treating cancer cachexia.
Cancer cachexia is a complex wasting syndrome characterized by significant loss of body weight and muscle mass in patients with advanced cancer. The disease is associated with increased systemic inflammation, altered neurohormonal signaling, and, in particular, an increased catabolic rate...
Author Correction: CD8 + T cells induce cachexia during chronic viral infection.
Effect of host and gut microbiota-altering interventions on sarcopenia or its defining parameters: a systematic review and meta-analysis of nutrition-based intervention studies.
AIM
To investigate effects of host- and gut microbiota (GM)-altering interventions on sarcopenia (parameters).
METHODS
Upon PROSPERO registration (CRD42022347363), six databases and one registry were searched until January 5th 2024 and updated on June 10th 2025 for diet, pre-, pro-, or synbiotics mono-interventions...
Air Pollution Exposure and Muscle Mass and Strength Decline in Older Adults: Results From a Swedish Population-Based Study.
BACKGROUND
Emerging evidence suggests that air quality may impact muscle health. However, most studies are limited by cross-sectional designs or short follow-ups. We assessed the association of long-term exposure to ambient air pollutants with changes in muscle mass and strength in...
Utilizing accelerated and delayed murine models of aging to address the "healthspan issue" – A review of skeletal muscle health.
The gap between lifespan and healthspan is increasing globally, resulting in millions of individuals spending additional years burdened by frailty or disease. This disparity, paired with the increasingly aged populations of Western nations, poses a palpable predicament to public health...
Chinese leek-derived extracellular vesicles ameliorate sarcopenia by regulating mitochondrial biogenesis and autophagy via AMPK and maintaining myosin homeostasis.
Sarcopenia, a prevalent age-related degenerative disorder, poses significant challenges in geriatric care. Chinese leek demonstrates therapeutic potential against sarcopenia progression, with emerging evidence suggesting its extracellular vesicles (EVs) may mediate these effects. Notably, plant-derived EVs have garnered increasing attention due...
Revisiting Cancer Cachexia Staging: Introducing an "At Risk" Category Based on AWGC Components.
Cancer cachexia is a multifactorial syndrome characterized by progressive weight loss, muscle wasting, and systemic inflammation. Early identification of individuals at risk for cachexia is essential for timely intervention, yet a universally accepted definition of the "at risk" stage remains...
