Transient transfection of these reporter plasmids to human lung cancer cell lines A549 and H446 with miR-182 or miR-185 mimic or microRNA control showed that transfection with miR-182 significantly reduced the luciferase activity caused by 3′UTR of SLC30A1 or SERPINB2 while transfection with miR-185 significantly reduced luciferase activity caused by 3′UTR of AKR1C1 (all P < 0.05). This evidence concerns the gene SLC30A1 and lung cancer.
