(D) Immunofluorescence and quantification of H3K9me3 in late-passage WT 4F cells. Scale bar, 10 μm. *p < 0.05, and ****p < 0.0001 according to one-way ANOVA with Bonferroni correction compared to control.
(E) Immunofluorescence and quantification of γH2AX foci in late-passage human 4F cells. Scale bar, 10 μm. ***p < 0.0005 and ****p < 0.0001 according to one-way ANOVA with Bonferroni correction compared to control.
(F) Immunofluorescence and quantification of H3K9me3 in late-passage human 4F cells. Scale bar, 10 μm. *p < 0.05, **p < 0.005, and ****p < 0.0001 according to one-way ANOVA with Bonferroni correction compared to control.
