Real-time PCR of representative genes in DHBV infected PDH, 0-day and 4-days post-infection. (A) Significant up-regulation of cDNAs (F22, F8, and F71) selected from the top of short-listed clones in the up-regulated gene table (Table-1). (B) Significant down-regulation of cDNAs (R73, R90, and R130) selected from the top of short-listed clones in the down-regulated gene table (Table-2). The Y-axis represents relative gene expression values obtained from the Pfaffl analysis (see Methods). Significant P-values (< 0.05) are indicated. The values in parenthesis indicate fold-change in expression.
