Cancer cachexia: A tumor-driven disorder of whole-body homeostasis.
Cancer cachexia is a systemic metabolic syndrome driven by tumor-induced disruption of whole-body homeostasis. Characterized by skeletal muscle atrophy and adipose tissue loss, cachexia leads to functional decline, impaired quality of life, reduced treatment tolerance, and poor survival across multiple...
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...
Moderate Aerobic Training Causes Muscle Wasting in a DMBA-Induced Sarcoma Rat Model.
Cancer cachexia, characterized by severe body weight loss, negatively affects patient quality of life and survival. Although moderate exercise benefits healthy and chronically ill individuals, and the effect of exercise in cachexia generally appears beneficial, conflicting results have been reported...
Glucagon-like peptide-1 receptor agonists and muscle strength changes in older adults: Risks beyond muscle mass reductions.
Gastric inhibitory polypeptide (GIP)/Glucagon-like peptide-1 (GLP-1) receptor agonists are increasingly prescribed for the management of obesity and type 2 diabetes, yet research pertinent to their effects on muscle health is limited. Considering the central role of muscle strength as a...
Tumour-host interactions in Drosophila: mechanisms in the tumour micro- and macroenvironment.
Traditionally, cancer has been viewed largely as a disease of the cell, with extensive research centred on how mutations in driver genes trigger cellular transformation. Beyond cell-intrinsic changes, cancer unfolds as a systemic disease driven by an intricate dialogue between...
Multi-omics profiling of cachexia-targeted tissues reveals a spatio-temporally coordinated response to cancer.
Cachexia is a wasting disorder associated with high morbidity and mortality in patients with cancer. Tumour-host interaction and maladaptive metabolic reprogramming are substantial, yet poorly understood, contributors to cachexia. Here we present a comprehensive overview of the spatio-temporal metabolic reprogramming...
Secreted protein acidic and rich in cysteine-guided biomimetic delivery of nano-antioxidants reverses muscle atrophy in a mouse model of sarcopenia.
Sarcopenia is currently classified as an unmet medical need with an increasing incidence because of population aging. Excessive reactive oxygen species (ROS) production plays a critical role in the pathogenesis of muscle atrophy, a key feature of sarcopenia, whereas edaravone...
Sex-specific differences between C-reactive protein and appendicular lean soft tissue index in heart failure: findings from the National Health and Nutrition Examination Survey.
INTRODUCTION
Heart failure (HF) is often accompanied by muscle wasting and elevated C-reactive protein (CRP). This study aimed to examine the association between CRP and appendicular lean soft tissue index (ALSTI) in patients with HF, focusing on potential sex differences.
METHODS
Using data...
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...
Blocking glycogen synthase 1 in white adipose tissue alleviates hypermetabolism following severe burn injury through inhibition of JAK2 by UDPG.
Browning of white adipose tissue (WAT) contributes to the sustained hypermetabolism observed in patients with burns. How glycogen metabolism in WAT is linked to burn-induced hypermetabolism remains unknown. We discover that burn-induced UCP1 expression in subcutaneous WAT is accompanied by...
Is Appendicular Lean Soft Tissue Mass a Clinically Valid Diagnostic Marker for Sarcopenia?
AIM
Geriatric experts have long debated the inclusion of appendicular lean soft tissue mass (ALSTM) in the diagnostic criteria for sarcopenia. This study examined whether a diagnostic model for sarcopenia that excludes appendicular lean soft tissue mass (ALSTM) is equivalent to...
Rise and Fall of Physical Capacity in a General Population: A 47-Year Longitudinal Study.
BACKGROUND
As we age, there is a progressive decline in skeletal muscle tissue and function that can become clinically significant in the sixth decade of life affecting independent living and health. Longitudinal observations in elite athletes show that peak physical performance...
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...
Jianpi Qiangji Granule ameliorates aging-associated sarcopenia via AMPK/PGC-1α axis in SAMP8 mice.
BACKGROUND
Sarcopenia is an age-related syndrome characterized primarily by the progressive decline of muscle mass and function. It is frequently associated with adverse outcomes such as falls, fractures, and hospitalization, often leading to substantial economic burdens and severe health hazards. At...
High Loss of Adipose Tissue During Neoadjuvant Chemotherapy Predicts Poor Prognosis in Patients With Gastric Cancer.
BACKGROUND
Gastric cancer (GC) patients often have nutritional risks or malnutrition, and neoadjuvant chemotherapy (NAC) tends to exacerbate malnutrition. Body composition parameters are associated with the prognosis of GC patients. Little is known about body composition changes during NAC and its...
