YAP1-Driven Pathogenic Fibro-Adipogenic Progenitors Secrete IL-6 and FGF21 to Mediate Muscle-Bone Crosstalk and Promote Bone Loss.

Sarcopenia, an age-related degenerative disease of skeletal muscle, is closely associated with osteoporosis and other bone disorders, partly due to dysregulated endocrine function of skeletal muscle. However, the specific cellular sources and molecular mechanisms driving this pathological secretory phenotype remain...

CXCL2 is a modifiable driver of sarcopenic inflammation attenuated by exercise in older women: Integrated transcriptomic and experimental evidence.

BACKGROUND

Sarcopenia is a progressive muscle-wasting condition driven in part by chronic inflammation; however, the specific inflammatory mediators that contribute to functional decline in humans and their responses to exercise remain poorly defined.

METHODS

We analyzed public ribonucleic acid (RNA) datasets to identify...

Selective Small-Molecule AdipoR1 Agonist 3-Hydroxy Pterocarpan Salt (CDRI-1709S) Ameliorates Skeletal Muscle Atrophy.

BACKGROUND

Skeletal muscle atrophy is a frequent comorbidity of metabolic disorders and chronic diseases, and despite its high prevalence, no pharmacological therapy is available, representing a major unmet clinical need. Adiponectin and its receptors are key regulators of skeletal muscle metabolism,...

Biological age-acceleration in relation to muscle mass, strength and function: findings from the Hertfordshire Cohort Study.

INTRODUCTION

Sarcopenia, the accelerated loss of muscle mass, strength and function with age, is associated with adverse health outcomes. DNA methylation accumulates across life and methylation clocks (which provide a measure of biological age) could potentially be used to predict individuals...

Association between GDF-15 and sarcopenia progression in older adults: results from a population-based study.

BACKGROUND

Growth differentiation factor-15 (GDF-15), a stress-induced cytokine, has been implicated in pathways related to muscle degeneration, although findings regarding its association with sarcopenia remain heterogeneous. This study investigated the association between serum levels of GDF-15 and sarcopenia progression in community-dwelling...

Understanding cachexia and muscle dysfunction in the context of metastatic breast cancer.

Cancer cachexia significantly impacts the quality of life of cancer patients, predicting therapy response and survival. Cachexia prevalence and severity increases over the course of disease progression, affecting up to 80% of patients with metastatic cancer. Despite this, cachexia is...

Pre-clinical cancer cachexia causes glucose hypermetabolism prior to overt weight loss.

PURPOSE

Cancer cachexia is a life-threatening complication of advanced malignancies, driven by profound systemic metabolic reprogramming and anorexia. Insulin action is markedly impaired in patients with cancer and may contribute directly to cachexia pathogenesis. However, the interplay between weight loss, food...

Sex-divergent skeletal muscle remodeling emerges early in cancer cachexia.

Cancer cachexia is characterised by progressive skeletal muscle wasting and dysfunction, yet the early events that precede overt muscle wasting remain poorly defined. Here, we utilised a time-coursed C26 carcinoma model in male and female mice to define the pre-cachectic...

Sarcopenia Predicts Postoperative Cognitive Impairment and Poor Surgical Outcomes in Older Adults: A Prospective Cohort Study.

BACKGROUND

Sarcopenia is a progressive skeletal muscle disorder prevalent in older adults, yet its role as a risk factor for acute postoperative cognitive decline-an early manifestation within the spectrum of perioperative neurocognitive disorders (PND)-remains underexplored. We hypothesize that preoperative sarcopenia increases...

Defining Healthy Weight Loss and Target Weight in the Era of Highly Effective Treatment of Patients With Obesity.

BACKGROUND

Highly effective anti-obesity medications (AOMs) induce substantial weight loss and have renewed debate on appropriate treatment targets. Weight loss comprises reductions in fat mass (FM) and fat-free mass (FFM), with skeletal muscle (SM) as the major component of FFM. Clinical...

Calcium Beta-Hydroxy-Beta-Methylbutyrate-Enriched Nutritional Supplementation During Dietary Weight Loss in Adults With Obesity: A Randomized Controlled Trial.

BACKGROUND

Dietary and pharmacologic weight loss can reduce skeletal muscle. Whether calcium beta-hydroxy-beta-methylbutyrate (CaHMB)-enriched supplementation preserves muscle while promoting fat loss in adults with obesity remains uncertain. We evaluated a CaHMB-enriched nutritional supplement during energy restriction.

METHODS

In this randomized, double-blind, controlled trial,...

Sarcopenic Obesity and Risk of Incident Type 2 Diabetes: A Prospective Cohort Study and Landmark Analysis From the UK Biobank.

OBJECTIVE

To examine whether sarcopenic obesity (SO) is associated with incident type 2 diabetes (T2D) beyond obesity or sarcopenia alone and whether associations differ by sex, age, and transitions in body composition phenotypes over time.
