Effect of exercise on muscle immune response and mitochondrial damage and their relationship with cancer-related fatigue: A URCC NCORP study.

10119Background: Chemotherapy (CT) via inflammation and oxidative stress can cause muscle inflammatory injury, mitochondrial damage, and cancer-related fatigue (CRF). Following muscle and mitochondrial damage, various cytoplasmic and mitochondrial components are released into circulation. HLA-DQB1 gene encodes a protein involved in the activation of immune response, and is not expressed in normal muscle cells but is up-regulated under highly inflammatory states. Mitochondrial gene MT-CO2 encodes subunit 2 of complex IV, which plays a critical role in energy metabolism and mitochondrial function. We investigated the (i) influence of an exercise intervention, Exercise for Cancer Patients (EXCAP), on gene expression levels of muscle immune response and mitochondrial damage and (ii) the relationships of these genes with CRF. Methods: In this nationwide, multicenter, phase III RCT conducted through the URCC NCORP Research Base, cancer patients (N = 350; mean age = 55.7) were randomized to 2 groups: (i) CT and ...
