Anticancer Drug-Induced Epithelial-Mesenchymal Transition via p53/miR-34a axis in A549/ABCA3 Cells

PURPOSE. Several anticancer drugs including bleomycin (BLM) and methotrexate (MTX) cause serious lung diseases such as pulmonary fibrosis. Although evidences showing the association of epithelial-mesenchymal transition (EMT) with pulmonary fibrosis are increasing, the mechanism underlying anticancer drug-induced EMT has been poorly understood. On the other hand, miR-34a, a non-coding small RNA, has been highlighted as a key factor to regulate...
