Knockdown of PRDX1 in lung cancer cells significantly inhibits transforming growth factor β1 (TGF‐β1)‐induced epithelial–mesenchymal transition (EMT) and cell migration, whereas PRDX1 overexpression enhances TGF‐β1‐induced EMT and cell migration 79. The gene discussed is TGFB1; the disease is lung cancer.
