Silencing of Sox9 inhibited cell proliferation of MG63 cells in vitro. A: CCK-8 assay demonstrated that silencing of Sox9 inhibited the cell proliferation capability of MG63 cells on the indicated time points following transfection with Sox9 siRNA (si-Sox9). B: Representative Western blot of Ki-67 protein in MG63 cells at 48 h after transfection with Sox9 siRNA and negative control siRNA (Con). C: Bar chart showing the relative intensity of Ki-67 protein as analyzed by Western blot (n = 3) with GAPDH used for normalization. *P < 0.05 vs. Con.
