Some evidences indicate that miRNA-195 can inhibit the ability of hepatoma cells to promote endothelial cell migration and angiogenesis, and can directly inhibit the migration and invasion of hepatoma cells, thereby inhibiting liver cancer (Wang et al., 2013).In osteosarcoma, miRNA-195 inhibits tumor migration and invasion by acting on fatty acid synthase (Mao et al., 2012).Based on these reports and current findings, we believe that the study of the mechanisms of action of miRNA-93 and miRNA-195 has profound implications for the clinical treatment of tumors. This evidence concerns the gene FASN and neoplasm.
