Figure 4From: The HBx oncoprotein of hepatitis B virus potentiates cell transformation by inducing c-Myc-dependent expression of the RNA polymerase I transcription factor UBFEffect of UBF overexpression on cell proliferation and cell survival of hepatoma cells. (A) Cell cycle distribution of vector or UBF transfected Huh7 cells represented as percentage of total cells in different phases. (B) Huh7 cells were transiently transfected with vector or UBF expression plasmids. Cell viability was measured by MTT assay. All quantitative values are mean ± S.D of three independent experiments. * represents a statistically significant difference of p <0.05.Back to article page
