It is shown that miR-490-3p inhibits cell growth by inducing apoptosis and cell invasiveness and metastasis by repression of epithelial-to-mesenchymal transition (EMT) through targeting FRAT1, VDAC1 and TGFβR1 in CRC cells [22–24], SMARCD1 in GC [25] and BUB1 in HCC [26]. The gene discussed is SMARCD1; the disease is gastric cancer.
