Poliovirus infection does not inhibit HIV-1 IRES activity in cells.

<p>(A) Schematic representation of the experimental protocol. (B). Whole cell lysates were analyzed for host proteins eIF4GI, eIFGII and PABP by western blotting analyses. GAPDH served as a loading control. (C). RLuc (top panel) and FLuc (bottom panel) activities over the course of poliovirus infection are shown. Luciferase activities at <i>t = 0</i> (before poliovirus infection) were set to 100%. Values represent the means ± SD from two independent experiments.
