Effects of substitutions in X-promoter on promoter activity, pgRNA expression and HBV-DNA level. (A) Relative luciferase activities of the constructs pGL3-B-HBx-promoter-wt and pGL3-B-HBx-promoter-mt carrying wild-type and mutated X-promoter respectively cloned in pGL3-Basic vector. Relative expression of pgRNA (B) and intracellular HBV-DNA level (C) as measured by quantitative real-time PCR, following transfection of the full-length, wild-type HBV/D (HBV/D-wt) and corresponding X-promoter-mutated HBV [HBV/D-mt(X-prom)] in Huh7 cells. Paired t-test p values; *p < 0.05, **p < 0.005, ***p < 0.0005.
