Abstract: Increasing evidence has shown that microRNAs play critical roles in the initiation and progression of non-small cell lung cancer (NSCLC). miR-185 is deregulated in various cancers, whereas its functional mechanism in NSCLC is still unclear. Here, we confirmed that the expression of miR-185 was significantly down-regulated in NSCLC tissues and cell lines. miR-185 over-expression caused significant suppression of in vitro cell proliferation, migration and invasion, and in vivo tumor growth. We subsequently identified that AKT1 was a target gene of miR-185. Re-expression of AKT1 could partially rescue the inhibitory effects of miR-185 on the capacity of NSCLC cell proliferation and motility. Collectively, we conclude that miR-185 has a critical function by blocking AKT1 in NSCLC cells, and it may be a novel therapeutic agent for miRNA based NSCLC therapy.
