ZEB1 and pulmonary fibrosis: In lungs, ZEB1 antisense RNA 1 (ZEB1-AS1) lncRNA acting as miR-141-3p sponge downregulates miR-141-3p levels, which increases the expression of miR-141-3p target ZEB1 in lung tissues of IPF and in TGF-ß1-stimulated alveolar type II epithelial cells, which promotes pulmonary fibrosis [43].
