Study Reveals How Pancreatic Cancer Triggers Severe Muscle Loss
Researchers used single-nucleus RNA sequencing to study pancreatic ductal adenocarcinoma (PDAC) cachexia, revealing how tumors systematically break down skeletal muscle. Using a KPC mouse model, they discovered a unique “cachectic cluster” of muscle nuclei that activates protein-degrading genes while suppressing structural genes. Not all muscle fibers were equally affected—fast-glycolytic Type IIb fibers suffered the most, […]
