Title: MiR-153 inhibits migration and invasion of human non-small-cell lung cancer by targeting ADAM19

Highlights: • Decreased miR-153 and up-regulated ADAM19 are correlated with NSCLC pathology. • MiR-153 inhibits the proliferation and migration and invasion of NSCLC cells in vitro. • ADAM19 is a direct target of miR-153. • ADAM19 is involved in miR-153-suppressed migration and invasion of NSCLC cells. - Abstract: MiR-153 was reported to be dysregulated in some human cancers. However, the function and mechanism of miR-153 in lung cancer cells remains unknown. In this study, we investigated the role of miR-153 in human non-small-cell lung cancer (NSCLC). Using qRT-PCR, we demonstrated that miR-153 was significantly decreased in clinical NSCLC tissues and cell lines, and downregulation of miR-153 was significantly correlated with lymph node status. We further found that ectopic expression of miR-153 significantly inhibited the proliferation and migration and invasion of NSCLC cells in vitro, suggesting that miR-153 may be a novel tumor suppressor in NSCLC. Further integrated analysis revealed that ADAM19 is as a direct and functional target of miR-153. Luciferase reporter assay demonstrated that miR-153 directly targeted 3′UTR of ADAM19, and correlation analysis revealed an inverse correlation between miR-153 and ADAM19 mRNA levels in clinical NSCLC tissues. Knockdown of ADAM19 inhibited migration and invasion of NSCLC cells which wasmore » similar with effects of overexpression of miR-153, while overexpression of ADAM19 attenuated the function of miR-153 in NSCLC cells. Taken together, our results highlight the significance of miR-153 and ADAM19 in the development and progression of NSCLC.« less
