In this study, three octaguanidinium dendrimer conjugatedmorpholino oligomers (vivo-MOs) targeting the EV-71 internal ribosome entry site (IRES) core sequence and the RNA-dependent RNA polymerase (RdRP) were tested for their inhibitory effects against EV-71. After incubation, the inoculum was removed and replenished with maintenance medium (DMEM with 2% FBS) with or without vivo-MOs. The inhibitory effects of the vivo-MOs were evaluated by plaque assay, TaqMan real-time RT-PCR and western blot analysis 24 h post-infection (hpi) as previously described (Tan et al., 2012 . As shown in Fig. 2 , both vivo-MOs targeting the EV-71 IRES stemloop region exhibited significant antiviral activity against EV-71 infection with reduction of virus-induced CPE ( Fig. 2A) , plaque formation (Fig. 2B) , RNA (Fig. 2C ) and capsid expression (Fig. 2D ) in a dose-dependent manner. ./cache/cord-262110-569a86u3.txt ./txt/cord-262110-569a86u3.txt
