Immunofluorescent staining of IRF3 in CTRL and Arih1 -WT -OE 4T1 cells and their quantifications. The nuclei were stained with DAPI. Scale bar, 10 μm; insets: Scale bar, 5 μm. Data represent means ± SEM, **** P < 0.0001. Each dot in the graph represents the percentage of counted nucleus IRF3 cells in each sample, and the total number of counted cells in each group is as follows: CTRL group ( n = 135 cells), Arih1 -WT -OE group ( n = 147 cells). For b, c, e data, Two-tailed t -test. Data shown in c–e are representative of three independent experiments. Source data are provided as a Source Data file.
