Elevated miR-145-5p is Associated with Chronic Obstructive Pulmonary Disease (COPD) Associated Skeletal Muscle Dysfunction and Triggers Apoptotic Cell Death in C2C12 Myotubes
Abstract:Skeletal muscle dysfunction is a common comorbidity of chronic obstructive pulmonary disease (COPD), and the molecular mechanisms regarding to the pathogenesis of this disease have not been elucidated. In this study, a novel miR-145-5p was significantly upregulated in the serum collected from patients with COPD-associated muscle atrophy, in contrast with the normal participants. Then, the primary myotubes was isolated and cultured in vitro, and we evidenced that silencing of miR-145-5p suppressed cell death an… Show more
