HBx-elevated NUSAP1 targeted by miR-18b promotes the proliferation of hepatoma cells in vitro. (A) The effect of miR-18b and NUSAP1 on HBx-induced cell proliferation was determined by MTT assays in H7402-X cells. (B) The effect of miR-18b and NUSAP1 on HBx-induced cell proliferation was determined by colony formation assays in H7402-X cells. (C) The effect of miR-18b and NUSAP1 on HBx-induced cell proliferation was determined by cell cycle assays in H7402-X cells. (D) The statistical results of cell cycle assays from Figure 5C and Figure S4C were shown. Error bars indicate SD. Student’s t-test ^*P < 0.05, ^**P < 0.01, NS, not significant.
