FIG. 4.
Inhibition of Raf or RalGDS signaling blocks activation of the hTBP promoter by the HBV X protein. Primary rat hepatocytes were transiently transfected with 5.5 μg of p−4500/+66hTBP-luc and 6 μg of pCMV-X together in the presence or absence of the following inhibiting agents: 0.5 μM wortmannin, 2 μg of RafM375, 50 μM U0126 (a MEK inhibitor), or 2 μg of RalBD. Cells treated with U0126 or wortmannin where exposed to inhibitor 14 h prior to harvesting of the transfected cells.
