Outline of Final Research Achievements |
The present study sought to evaluate the effect of electrical stimulation (ES) by using kilohertz frequency on muscle atrophy and oxidative metabolism impairment induced by cachexia. Cachexia induced increased plasma levels of inflammatory cytokines, significant muscle mass loss, decreased fiber cross-sectional area, and an up-regulation of atrogin-1 and ubiquitinated proteins in the skeletal muscle. In addition, Cachexia decreased succinate dehydrogenase (SDH) and citrate synthase (CS) activity, PGC-1α expression, and increased the phosphorylation of p38 MAPK. ES attenuated the sepsis-induced loss of muscle mass and decreased muscle fiber cross-sectional area, as well as attenuated the atrogin-1 and ubiquitinated protein up-regulation. ES also attenuated the changes in SDH and CS activities, p38 MAPK, and PGC-1ɑ. These results suggest that ES could prevent muscle atrophy and decrement in muscle oxidative metabolism induced by pro-inflammatory cytokines in cachexia.
