FIG. 7.

Efflux of EGFP-NLS from the nuclei of poliovirus-infected cells lacking caspase-3 and -9. MCF-Cas9DN cells were transiently transfected with pEGFP-NLS; at 48 h posttransfection they were mock infected (a) or infected with poliovirus at an input MOI of ∼500 PFU/cell (b) and inspected under a fluorescence microscope at 2 h p.i.
