STAT3 and Cachexia: The decline in skeletal muscle mass is attributed to an imbalance between anabolic and catabolic processes, along with the activation of various signaling pathways, including the signaling transducer and activator of transcription 3 (STAT3), forkhead box protein O3, and nuclear factor‐kappa B.18, 19, 20, 21, 22, 23Notably, the IL‐6/STAT3 pathway may play a vital role in the advancement of cachexia.19, 24, 25
