TGFB1 and idiopathic interstitial pneumonia: To understand the roles of lncRNAs in IPF, we performed RNA sequencing analysis to reveal genome‐wide changes of lncRNAs in hypoxia and/or TGFβ1‐treated human lung fibroblasts and further investigated the regulatory mechanisms of one of the identified lncRNAs, FENDRR by hypoxia and TGFβ1.
