In a previous study, we first revealed the differentially expressed profiles of lncRNAs in BLM-induced pulmonary fibrosis using microarray analysis and demonstrated that the regulatory mechanism of lncITPF on pulmonary fibrosis is to form an lncITPF–hnRNP L complex to facilitate pulmonary fibrosis [16,17]. This evidence concerns the gene HNRNPL and pulmonary fibrosis.
