MicroRNA-195 suppresses osteosarcoma cell invasion and migration in vitro by targeting FASN.

ABSTRACT: microRNAs are involved in different cancer-related processes. miR-195, one of the miR-16/15/195/424/497 family members, has been shown to act as a tumor suppressor during tumorigenesis. However, the function of miR-195 in osteosarcoma is still unclear. In our study, the miR-195 expression level was upregulated in osteosarcoma cells, by transfection with miR-195, and the fatty acid synthase (FASN) mRNA and protein expression levels were measured by RT-PCR and western blotting. Cell migration and invasion was measured using wound healing migration and Transwell invasion assays. We found that the upregulation of miR-195 greatly decreased cell invasion and the migration of U2OS. We also identified that FASN may be a direct target of miR-195 by the luciferase activity assay. These findings prov
