Fig. 1From: Lung transcriptomics reveals the underlying mechanism by which aerobic training enhances pulmonary function in chronic obstructive pulmonary diseaseCOPD mouse model establishment process and exercise intervention protocol. The mice were randomly divided into CG, MG and EG (n = 8). MG and EG were exposed to smoke for 24 weeks to replicate the COPD model, and the latter received 9 weeks of aerobic exercise intervention. Finally, multiple indicators in each group were examined. CG, control group; MG, model group; EG, exercise group. Values represented the means ± SDBack to article page
