This study confirmed the effects of improving lung damage of celecoxib using an animal model of chronic obstructive pulmonary disease(COPD). It was induced in models LPS + CSE and performed in vitro and in vivo. MTT assay and real-time PCR were performed in MRC5 cells as in vitro, and mRNA expression, BALF, collagen content, and protein expression were confirmed as in vivo. Celecoxib reduced the number of inflammatory cells, cytokine and soluble protein accumulation in BALF, decreased body weight and lung weight in animal models, and improved lung collagen deposition. In addition, the reduction of EMT markers was confirmed through Western blotting and real-time PCR. Consequently, celecoxib is thought to improve lung damage of COPD induced to LPS+CSE by regulating EMT.
