ITGBL1 and idiopathic pulmonary fibrosis: For instance, during the COVID-19 crisis, lncRNA (i.e., lncRNA idiopathic pulmonary fibrosis [ITBF]) was found at elevated levels and was associated with the integrin subunit beta like 1 (ITGBL1) gene in pulmonary fibrogenesis responsible for fibroblast differentiation and, thus, pulmonary fibrosis.
