WT1 and infection: After the resazurin treatment of infected Reh cells at the indicated post-infection times, the fluorescence analysis revealed that both at 12 and 24 h.p.i., the mitochondrial function and cell viability were dramatically decreased by Wt1-5 infection, which was more evident at higher MOI values and longer post-infection times (24 h.p.i.)(Figure 3A).
