Task: Answer Verification
Input (English): Question: Does nitric oxide exert protective effects against bleomycin-induced pulmonary fibrosis in mice?
Answer: These results provide the first direct evidence that a lack of all three NOS isoforms led to a deterioration of pulmonary fibrosis in a BLM-treated murine model. We speculate that the entire endogenous NO and NOS system plays an important protective role in the pathogenesis of pulmonary fibrosis.
Output (English): yes
