In contrast, miR-200c is reduced in the lung of the bleomycin IPF model and in epithelial cells after treatment with TGF-β1, and the diminution of miR-200c was related to the development of EMT and loss of the ability of alveolar epithelial cells type II to differentiate into alveolar epithelial cells type I [110,111,112]. The gene discussed is TGFB1; the disease is idiopathic interstitial pneumonia.
