Tumor-suppressive microRNA-218 inhibits cancer cell migration and invasion via targeting of LASP1 in prostate cancer.
Bottom Line: Our recent studies of the microRNA (miRNA) expression signature in prostate cancer (PCa) indicated that miRNA-218 (miR-218) was significantly downregulated in clinical specimens, suggesting that miR-218 might act as a tumor-suppressive miRNA in PCa.Luciferase reporter assays showed that miR-218 directly regulated expression of LASP1.Our data on pathways regulated by tumor-suppressive miR-218 provide new insight into the potential mechanisms of PCa oncogenesis and metastasis.

Mentions: The XTT assay demonstrated that cell proliferation was not inhibited in miR-218 transfectants in comparison with the mock or miR-control transfectant cells (Fig. 2a).
