Associations Between Gut Microbiota and Mitochondrial Metabolites, with Growth Differentiation Factor-15 as a Marker of Oxidative Stress in Heart Failure vs. Healthy Ageing.
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 and Obesity Each Increase Tumor Cell Proliferation and Muscle Wasting in Experimental Cancer Cachexia.
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...
Impact of probiotic, prebiotic, and synbiotic supplementation on the gut microbiome in older adults with sarcopenia, obesity, and sarcopenic obesity.
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,...
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...
Small-Molecule Targeting MuRF1 Protects Against Denervation-Induced Diaphragmatic Dysfunction: Underlying Molecular Mechanisms.
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...
EyaHOST, a modular genetic system for investigation of intercellular and tumor-host interactions in Drosophila melanogaster.
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...
Glucagon-like peptide-1 receptor agonists and sarcopenia-related markers in diabetes: A systematic review and meta-analysis.
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...
Drug Candidate BIO101 for Spinal Muscular Atrophy as Monotherapy or Combined With the Antisense Oligonucleotide ASO-10-27.
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...
Association of Hormonal Status With Sarcopenia, Frailty and Outcome in Patients With Decompensated Cirrhosis.
BACKGROUND AND AIMS
Sarcopenia and frailty have been associated with hormonal dysregulation in non-cirrhotic populations. The aim of the study was to evaluate hypothalamic-pituitary-adrenal and gonadal (HPA-HPG) axes as well as growth hormone/insulin-like growth factor-1 (GH/IGF-1) levels in patients with cirrhosis...
Interplay Between mTORC1 Signaling and Iron Homeostasis in Muscle Atrophy.
The mechanistic target of rapamycin complex 1 (mTORC1) plays an important role in maintaining skeletal muscle homeostasis by regulating cell growth, protein degradation, and nutrient sensing. Beyond its role in muscle growth and atrophy, recent findings suggest that mTORC1 also...
CXCL14 Promotes Skeletal Muscle Mass Growth and Attenuates Lipopolysaccharide- and Dexamethasone-Induced Muscle Atrophy in Cultured Myotubes and Mouse Models.
BACKGROUND
Skeletal muscle mass is regulated by secretory factors derived from myofibers and muscle-resident cells. Identifying these factors and understanding their mechanisms is critical for combating muscle wasting disorders. This experimental study investigates the role of CXCL14, a chemokine primarily secreted...
Sex-specific survival but not tissue wasting in the KPP mouse model of pancreatic cancer-induced cachexia.
Cancer cachexia, a multifactorial condition resulting in muscle and adipose tissue wasting, reduces the quality of life of many people with cancer. Cachexia is highly prevalent in people with pancreatic ductal adenocarcinoma (PDAC), and many animal models of pancreatic cancer...
A Novel ceRNA Axis LOC121818100/Novel-miR-400/SSRP1 Regulated Muscle Growth and Injury Repair in Sheep.
In mammals, skeletal muscle growth is a delicate process. The construction of competitive endogenous RNA (ceRNA) networks provides an effective way to analyse the molecular mechanism of complex trait formation. The aim of this study was to investigate the role...
Fibroblast Growth Factor 23 and Sarcopenia in Maintenance Haemodialysis Population.
Sarcopenia is defined as the loss of muscle mass, strength, and/or performance. It is strongly associated with all-cause mortality. Fibroblast growth factor 23 (FGF23) is markedly elevated in patients with chronic kidney disease, especially those receiving maintenance dialysis. FGF23 has...
GL261 glioblastoma induces delayed body weight gain and stunted skeletal muscle growth in young mice.
The survival rate for children and adolescents has increased to over 85%. However, there is limited understanding of the impact of pediatric cancers on muscle development and physiology. Given that brain tumors alone account for 26% of all pediatric cancers,...
