Although the remaining lncRNA-related protein-coding genes exhibited no expression changes, these genes, such as RGD1564927 (similar to TGFB-induced factor 2, SMAD family member 2, and mitogen-activated protein kinase associated protein 1), have already been proven as important factors in pulmonary fibrosis [34–36]. Here, MAPKAP1 is linked to pulmonary fibrosis.
