Epoxomicin did not inhibit the EV71-induced PMLIII and IV degradation. Cell lysates were prepared from 293T cells infected or mock-infected with EV71 at a multiplicity of infection (MOI) of 5 for 24 or 48 h in the presence or absence of epoxomicin (1 µM). At 24 h post-infection (p.i.) (left panels) or 48 h p.i. (right panels), 60 μg of protein extracted from each treatment were separated on SDS-PAGE and analyzed by performing a Western blot analysis using antibodies specific for PMLIII and IV (top panels), VP1 (middle panels), and GAPDH, which served as an internal loading control (bottom panels). PMLIII and IV were quantified by performing densitometry and are presented relative to the mock infection, which was set as 1.0. VP1 was quantified and is presented relative to that in the EV71-infected 293T cells at 24 h p.i. (left panels) or 48 h p.i. (right panels). The density value of VP1 without epoxomicin is set as 1.0. The experiment was performed three times, and representative results are shown.
