TGF-β1 expression and activation in the lungs. WT and Opn KO mice were exposed to DM or 40 μg MWCNTs for 7 or 28 days. (a) Immunohistochemistry of TGF-β1 on lung tissue sections. Red indicates positive staining of TGF-β1 (scale bar: 20 μm). Relative intensity of positive staining was measured and presented as mean ± SD (n = 4). (b) Immunoblotting of TGF-β1 (n = 2). Actin was used as the loading control
