Abstract: MicroRNAs (miRNAs) are a class of small non-coding RNAs that play key roles in cancer development and progression. Therefore, the discovery of miRNAs may provide a new and powerful tool for understanding the mechanism of carcinogenesis. In the present study, we aimed to investigate the functional significance of miR-630 and to identify its possible target genes in human non-small cell lung cancer (NSCLC). Our results showed that miR-630 was significantly down-regulated in NSCLC tissues and cell lines. The enforced expression of miR-630 was able to inhibit cell proliferation, migration, and invasion of NSCLC cells. Moreover, our results further revealed that LMO3, a nuclear LIM-only proteins, was identified as a target of miR-630. Restoration of LMO3 remarkably reversed the tumor-suppressive effects of miR-630 on cell proliferation, migration, and invasion in NSCLC cells. Therefore, we demonstrated that miR-630 suppressed the proliferation, migration, and invasion of NSCLC cells by down-regulating LMO3 expression, suggesting miR-630 as a potential therapeutic target for the treatment of human NSCLC in the future.
