Immortalized primary bronchial epithelial cell line (BEAS-2B cells), human primary bronchial epithelial cells (PBECs), and PBECs derived post-lung transplant were transfected with miR-200b-3p mimics and EMT marker expression was examined at RNA and protein level. miRNA target studies were performed and validated using computational tools and luciferase assay.

Furthermore, miR-200b-3p mimics reversed established TGF-\u03b21\u2013induced EMT in BEAS-2B cells. miR-200b-3p targets, ZNF532, and ZEB2 were validated as direct targets using luciferase assay. miR-200b-3p mimics suppress TGF-\u03b21\u2013induced EMT via inhibition of ZNF532 and ZEB2. In situ hybridization showed that miR-200b-3p is expressed in the normal lung epithelium.
