To further investigate the mechanism of miR-149 in regulating the biological behavior of gastric cancer cells, we predicted that miR-149 had binding sites with FOXC1 3′-UTR through the TargetScan database (Figure 3(a)) and constructed FOXC1 wild-type and mutant 3′-UTR luciferase vectors. Here, FOXC1 is linked to gastric cancer.
