MicroRNAs (miRNAs) as a class of small noncoding RNA molecules regulate the expression of targeted gene. The dysregulation of microRNAs is reported to be involved in carcinogenesis and tumor progression. Here, we identified miR-140-3p as a downregulated microRNA in most cancer tissues including lung cancer tissues, compared with their normal counterparts. MiR-140-3p was observed to perform its tumor suppressor function via its inhibition on cell growth, migration and invasion but its induction of cell apoptosis. Furthermore, the growth of non-small-cell lung cancer (NSCLC) cells in nude mouse models were suppressed by overexpression of miR-140-3p. ATP8A1 was demonstrated as a novel direct target of miR-140-3p using a luciferase assay. The increased level of intracellular ATP8A1 protein attenuated the inhibitor role of miR-140-3p in the growth and mobility of NSCLC cell. A regulation mechanism of miR-140-3p for the development and progression of NSCLC through downregulating the ATP8A1 expression was first discovered in the present study.
