Skeletal muscle health and regeneration are highly orchestrated processes governed by a complex interplay of muscle stem cells, fibro-adipogenic progenitors, immune cells, and endothelial cells. Among these cell types, endothelial cells play a central role not only by regulating blood...
BACKGROUND
Cancer cachexia is a debilitating syndrome marked by involuntary weight loss resulting from reduced food intake and intricate metabolic reprogramming. Despite its high prevalence, cancer cachexia remains undertreated, with a lack of effective and approved pharmacotherapies. Ghrelin has emerged as...
BACKGROUND
Sarcopenia, the age-related loss of muscle mass and strength, poses a significant health and economic burden. This systematic review and meta-analysis evaluates circulating biomarkers (activin A, follistatin, growth differentiation factor (GDF-15), myostatin, growth hormone, insulin growth factor-1 (IGF-1), free and...
Muscle mass is a strong indicator of overall health in older adults. In healthy individuals, an adequate muscle mass is maintained through a balance between anabolic pathways, such as the mTOR pathway (mammalian target of rapamycin), and catabolic pathways, including...
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...
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...
Growth differentiation factor-15 (GDF-15) is an established marker of oxidative stress and a general stress-response mitokines. In this study, we aim to investigate the association of GDF-15 with the metabolic signature of gut and mitochondrial activity in HF and ageing...
High fat diet (HFD) and associated obesity are suggested to predispose to cancer development, complicate cancer treatment, and accelerate mortality. Paradoxically, obese patients with lung cancer are reported to live longer, suggesting that high body mass is protective. Given that...
Gut microbiome plays an important role in several metabolic, immune, and inflammatory pathways; however, there is limited evidence for its role in body composition and musculoskeletal health. Sarcopenia, defined as a loss of skeletal muscle mass and function, and obesity,...
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...
BACKGROUND
Mechanical inactivity rapidly induces diaphragm muscle fibres' contractile dysfunction and atrophy. Diaphragm weakness can impair respiratory function, quality of life and increase risks of morbidity and mortality. Muscle RING-finger protein-1 (MuRF1) expression is upregulated during denervation and muscle inactivity and...
Studying intercellular and interorgan interactions in animal models is key to understanding development, physiology, and disease. We introduce EyaHOST, a system for clonal combinatorial loss- and gain-of-function genetics in fluorescently labeled cells under QF2-QUAS eya promoter control. Distinct from mosaic...
AIMS
GLP-1 receptor agonists (GLP-1RAs) are first-line therapies for type 2 diabetes (T2DM) due to their additional weight-lowering and cardiovascular benefits. However, their impact on muscle mass is debated, posing a concern for sarcopenia in older adults with T2DM. This systematic...
BACKGROUND
Spinal muscular atrophy (SMA) is a neuromuscular disease caused by loss of survival of motor neuron (SMN) protein inducing progressive muscle weakness and atrophy due to motor neurons degeneration. Despite benefits of SMN restoration therapies in patients, motor defects are...
