Cancer IDO1-Mediated Tryptophan-Kynurenine Metabolic Reprogramming to Drive Skeletal Muscle Atrophy and Cachexia Acceleration.
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...
