Cachexia-induced alterations of miR-27a-3p drive cell-type specific effects in FAPs and tumor cells that coincide with muscle wasting.
The contribution of muscle-resident stromal cells to cancer-associated muscle wasting is poorly understood. We characterized the role of fibroadipogenic progenitors (FAPs) in pancreatic cancer-associated cachexia and investigated how dysregulated microRNAs in the tumor and FAPs drive muscle wasting. In cancer-bearing...
Development of a spatially defined 3D in vitro coculture construct modelling pancreatic cancer-associated cachexia.
Pancreatic cancer-associated cachexia is marked by adipose tissue wasting, thermogenic remodeling, and a state of hypermetabolism, yet robust preclinical models to study these phenomena are lacking. In this study, we present a spatially defined three-dimensional (3D) coreshell microcuboid coculture platform...
A Novel Mouse Model to Identify Antigen-Specific Immune Responses in Pancreatic Cancer Cachexia.
BACKGROUND
Pancreatic Ductal Adenocarcinoma (PDAC) has a dismal five-year survival rate of 13% and is closely associated with cachexia. Cancer cachexia is a multifactorial syndrome characterized by irreversible wasting of skeletal muscles, fat loss and systemic inflammation. While cachexia is known...
Mitochondrial Permeability Transition in Skeletal Muscle Phenocopies Muscle Alterations seen in Cancer Cachexia and other Wasting Conditions.
BACKGROUND
Skeletal muscle in wasting conditions often exhibits a common set of phenotypes that include atrophy, mitochondrial respiratory dysfunction, and fragmentation of the acetylcholine receptor (AChR) cluster at the endplate. Mitochondria are frequently implicated in driving muscle pathology in these conditions,...
The canonical ER stress IRE1α/XBP1 pathway mediates skeletal muscle wasting during pancreatic cancer cachexia.
Cancer cachexia is a debilitating syndrome characterized by the progressive loss of skeletal muscle mass with or without fat loss. Recent studies have implicated dysregulation of the endoplasmic reticulum (ER) stress-induced unfolded protein response (UPR) pathways in skeletal muscle under...
Cachexia in Pancreatic Cancer: New Insights to Impact Quality of Life and Survival.
Introduction: Cancer cachexia is associated with systemic inflammation and metabolic derangement, leading to muscle atrophy, which affects over 80% of pancreatic cancer patients, the highest rate among all malignancies, negatively impacting quality of life and significantly reducing survival rate. Malnutrition,...
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...
MicroCT enables simultaneous longitudinal tracking of murine pancreatic cancer progression and cachexia.
Dual-contrast microCT provides high-resolution, whole-body, non-invasive imaging in orthotopic murine PDAC models, enabling simultaneous tracking of tumor growth, metastasis, and skeletal muscle wasting-offering a clinically relevant, translational imaging platform.
Integrating Body Composition and Nutritional Indices: A Novel Prognostic Tool for Survival in Pancreatic Cancer.
Sarcopenia and malnutrition have been independently associated with a poorer prognosis in pancreatic ductal adenocarcinoma (PDAC), but their combined association with patient outcomes is not fully understood. This study aimed to systematically evaluate the synergistic effects of body composition parameters...
Pancreatic Cancer-Derived Extracellular Vesicles Enriched with miR-223-5p Promote Skeletal Muscle Wasting Associated with Cachexia.
Pancreatic ductal adenocarcinoma (PDAC) with cachexia-related muscle wasting as the main manifestation is associated with poor overall survival. Extracellular vesicles (EVs) are key mediators of inter-organ communication. Here, EVs and EV-microRNAs (miRNAs) are identified as mediate PDAC-skeletal muscle communication. EVs...
Histidine decarboxylase inhibition attenuates cancer-associated muscle wasting.
Cancer cachexia is a multifactorial syndrome involving muscle and fat wasting, inflammation, and metabolic dysfunction. Across cancer subtypes, pancreatic cancer has one of the highest cachexia incidence rates at ∼80%. Given the advanced age of most pancreatic cancer patients, we...
AI-based CT assessment of sarcopenia in borderline resectable pancreatic Cancer: A narrative review of clinical and technical perspectives.
Sarcopenia, defined as the progressive loss of skeletal muscle mass and function, has been associated with poor prognosis in patients with pancreatic cancer, particularly those with borderline resectable pancreatic cancer (BRPC). Although body composition can be extracted from routine CT...
Local Inflammation Precedes Diaphragm Wasting and Fibrotic Remodelling in a Mouse Model of Pancreatic Cancer.
Cancer cachexia represents a debilitating muscle wasting condition that is highly prevalent in gastrointestinal cancers, including pancreatic ductal adenocarcinoma (PDAC). Cachexia is estimated to contribute to ~30% of cancer-related deaths, with deterioration of respiratory muscles suspected to be a key...
Skeletal Muscle Index Changes on Locoregional Treatment Application After FOLFIRINOX and Survival in Pancreatic Cancer.
Patients with borderline resectable (BR) or locally advanced pancreatic cancer (LAPC) require complex management strategies. This study evaluated the prognostic significance of the perichemotherapy skeletal muscle index (SMI) and carbohydrate antigen 19-9 (CA 19-9) in patients with BRPC or LAPC...
Integrative study of skeletal muscle mitochondrial dysfunction in a murine pancreatic cancer-induced cachexia model.
Pancreatic ductal adenocarcinoma (PDAC), the most common pancreatic cancer, is a deadly cancer, often diagnosed late and resistant to current therapies. PDAC patients are frequently affected by cachexia characterized by muscle mass and strength loss (sarcopenia) contributing to patient frailty...
