| Outline of Final Research Achievements |
We studied the pathoetiology of COPD and obtained the following results: 1) In the lungs of COPD patients, chronic DNA damage contributes to cell senescence, apoptosis, chronic inflammation and tumorigenesis; 2) In mice exposed to cigarette smoke, oxidative damage occurs in the heart and adipose tissue as well as the lungs; 3) In mice repeatedly exposed to bromodeoxyuridine, chronic DNA damage causes persistent lung inflammation; 4) In mice repeatedly exposed to naphthalene, airway fibrosis occurs due to chronic airway epithelial injury; 5) In mice exposed to bleomycin, DNA damage in the lungs causes chronic lung inflammation; 6) Based on the above results, we proposed an evolutionary medicine approach to understand factors that contribute to the development of COPD.
