Representative Western blot analysis of A p-p53; B Bax and Bcl-2; and C cleaved caspase-3, caspase-3, cleaved caspase-9, and caspase-9, with β-actin as a loading control in human pulmonary alveolar epithelial cells exposed to 0–200 μg/ml biomass combustion soluble constituents (BCSCs). The relative gray value of D p-p53, E Bcl-2, F Bax, G Bcl-2/Bax, H cleaved caspase-3 and I cleaved caspase-9 in human pulmonary alveolar epithelial cells. (*P < 0.05, **P < 0.01)
