In vitro, cell lines transfected the set of the miRNAs significantly reduced their malignant potentials. Finally, we analyzed expression level of the set of miRNAs in a cohort of 67 stage IV CRCs. CRCs with the lower expression level of the set of miRNAs showed poor outcome compared with those with the higher expression level. Our data indicate that the miRNAs is promising prognostic biomarkers and therapeutic targets for anti-metastatic therapy in CRC.
