MTA1 and idiopathic pulmonary fibrosis: Proteins of the MTA family have been identified as critical regulators of the EMT process, especially MTA1.10, 11 For instance, MTA1 enhances cell invasion and migration by inducing EMT in several types of cancers.12, 13, 14 We, therefore, have been suggested that MTA1 may involve in TGF‐β1‐indued EMT and play a potential role during the development of IPF.
