[Retracted] PM2.5 Exposure Induces Lung Injury and Fibrosis by Regulating Ferroptosis via TGF-β Signaling

Figure 5

PM2.5 increases TGF-beta1/smad3 expression and decreases TET2 and 5hmC expression in primary mouse lung epithelial cells. (a–c) The primary mouse lung epithelial cells were treated with PM2.5 at the indicated doses. (a, b) The expression of TGF-β, Smad3, and TET2 was analyzed by Western blot analysis. (c) The levels of 5hmC were examined by ELISA assays. .
