Overexpression of Apolipoprotein A1 in the Lung Abrogates Fibrosis in Experimental Silicosis
(A) Masson’s trichrome staining of lung sections. Scale bar = 20 µm. (B) Soluble lung collagen was measured using a Sircol assay. **p<0.01 compared with the Silica group (D15 and D30). (C) The level of the active TGF-b1 in the lung was measured by ELISA. **p<0.01 compared with the Silica group (D15 and D30).
