HO-1 expression in the lungs in murine silicosis. Mice were instilled with 2.5 mg of silica particles. a The lung samples collected 2 days after silica instillation were subjected to SDS-PAGE (10%; 15 μg of total protein/lane) and analyzed by Western blotting using anti-HO-1 and anti-actin antibodies. b Densitometric analysis of band intensity representing the mean ± SD level of HO-1 protein relative to actin (n = 3/group). The ratio of HO-1/actin was significantly increased in the lungs in murine silicosis compared to the saline control (Student’s t-test). * P < 0.05
