HBx-elevated NUSAP1 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 HepG2-X cells. (B) The effect of miR-18b and NUSAP1 on HBx-induced cell proliferation was measured by colony formation assays in HepG2-X cells. (C) The effect of miR-18b and NUSAP1 on HBx-induced cell proliferation was examined by cell cycle assays in HepG2-X cells. Error bars indicate SD. Student’s t-test, ^*P<0.05,^**P<0.01, NS, not significant.
