Nifuroxazide, an anti-diarrheal drug, suppresses the expression of inflammatory factors such as IL-6 and IL-4 along with α-SMA and collagen I expression in both TGF-β-stimulated human and bleomycin-injured mouse fibroblast models, ameliorating pulmonary fibrosis [47]. The gene discussed is TGFB1; the disease is pulmonary fibrosis.
