Figure 1From: NDV-induced apoptosis in absence of Bax; evidence of involvement of apoptotic proteins upstream of mitochondriaComparison of the percentage of PI stained NDV-infected cells. Data are obtained at different time points 18 h, 36 h and 48 h by flowcytometry. Error bars indicate standard error of the mean from three independent measurements. The difference in the percentage of cell death in HCT116 Bax−/− cells compared to wt HCT116 at 48 h post-infection was statistically significant. *, p < 0.05.Back to article page
