Figure Lengend Snippet: ZEB1 KO in human and murine fibroblasts results in increased susceptibility to reovirus infection and reovirus-mediated apoptotic cell death (A, E, and I) Cell viability (%) relative to mock following infection with reovirus at multiple MOIs, as measured by a WST-1 assay. RLT-PSC (A) were infected for 4 days, hPS1 (E) for 6 days, and KPC3-CAF1 (I) for 3 days. Significance was calculated using two-way ANOVA with correction for multiple testing (Šídák’s test), significance is depicted at MOI 10, ∗ p ≤ 0.05, ∗∗ p ≤ 0.01, ∗∗∗∗ p ≤ 0.0001. Data are derived from a representative experiment and plotted as mean ± SD. (B, F, and J) Overlay of phase-contrast and GFP images of CellEvent Caspase 3/7 assay of RLT-PSC (B), hPS1 (F), and KPC3-CAF1 (J) WT and ZEB1 KO cells. Cells were infected with R124 MOI 10 for 36, 48, and 24 h, respectively. Scale bars: 200 μM. (C, G, and K) Quantification of CellEvent Caspase 3/7 fluorescent signal over time, during infection with reovirus R124 MOI 10 for 36 (RLT-PSC, C), 48 (hPS1, G), or 24 h (KPC3-CAF1, K). Significance was calculated using two-way ANOVA with correction for multiple testing (Šídák’s test), ∗∗∗∗ p ≤ 0.0001. Data are derived from a representative experiment and plotted as mean ± SD. (D, H, and L) Western blot for reovirus Sigma3 expression (41 kDa) and vinculin (117 kDa) as loading control in WT and ZEB1 KO cells following reovirus infection at different MOIs. RLT-PSC (B) and hPS1 (E) were infected for 2 days and KPC3-CAF1 (H) for 1 day.
Article Snippet: For chromatin immunoprecipitation assays, hPS1 ZEB1 KO cells, rescued with ZEB1 cDNA (clone 2D12+ZEB1), were cultured for 48 h. One day prior to fixation of the cells, Protein A dynabeads (Thermo Fisher Scientific) were coated with 4 μg ZEB1 (Proteintech 21544-1-AP, Manchester, UK) or 4 μg rabbit IgG control Ab (PP64, Sigma-Aldrich) overnight in PBS/1% BSA (>98% BSA free, Sigma-Aldrich).
