TET1 and idiopathic pulmonary fibrosis: MiR-30a is downregulated in IPF patients, and further in vitro analyses indicate that overexpression of miR-30a directly targets ten-eleven translocation 1 (TET1) that modulates dynamin-related protein1 (Drp-1) promoter hydroxymethylation and thereby, show antifibrotic effect and defensive role against pulmonary damage (Zhang S. et al., 2017).
