Downregulation of DKK3 counteracted the proliferation arrest by miR-3690-in. (A) Western blot analysis verified that silencing DKK3 effectively decreased the expression of DKK3 in miR-3690-in-transfected K1 cells. (B) miR-3690-in-transfected K1 cells after transfection with DKK3-siRNAs promoted the anchorage-independent growth. Representative quantification of colonies that were >0.1 mm. (C) Representative quantification of the BrdU incorporation assay. Each bar represents the mean of three independent experiments. *P<0.05. miR-3690-in, microRNA-3690-inhibitor; DKK3, Dickkopf-related protein 3; siRNA, small interfering-RNA; NC, negative control.
