Exercise-induced metabolic reprogramming in lung cancer and its translational implications for therapeutic advancement.

Lung cancer remains one of the leading causes of cancer-related mortality worldwide, characterized by profound metabolic reprogramming that sustains malignant growth, immune evasion, and therapeutic resistance. Aberrant activation of glycolysis, increased fatty acid synthesis and uptake, and dysregulated glutamine metabolism provide energy and biosynthetic substrates while reshaping the tumor microenvironment through lactate accumulation, acidosis, and angiogenic signaling. Experimental and clinical …

Chemotherapy-Induced Skeletal Muscle Dysfunction and Cognitive Impairment: A Muscle-Brain Mechanistic Framework With Implications for Exercise Oncology.

Chemotherapy commonly induces skeletal muscle dysfunction and cognitive impairment, complications that reduce treatment tolerance and quality of life. Skeletal muscle mass frequently declines during chemotherapy, with cohort studies reporting losses of 3%-10% across treatment courses, while chemotherapy-induced cognitive impairment affects up to one-third of patients. Emerging evidence indicates that chemotherapeutic agents impair mitochondrial function in peripheral tissues, including skeletal muscle, …

Exercise-Induced Skeletal Muscle Secretory Factors and Macrophage Functional Remodeling: Mechanistic Advances.

Regular exercise mediates inter-tissue communication between skeletal muscle and the immune system through skeletal muscle-derived secretory factors, providing an important molecular basis for the beneficial effects of exercise on chronic inflammation, metabolic dysregulation, and impaired tissue repair. As key effector cells of the innate immune system, macrophages do not simply conform to a dichotomous classification of classically activated M1 macrophages …
