The absence of GL1 impaired SG formation during arsenite-induced stress compared to sorbitol-induced stress. Percentage of cells with SGs: (a,b) Cells treated with 500 µM arsenite for 15 to 30 min or (c,d) 300 mM sorbitol for 1.5 to 3 h. (a,c) Immunofluorescence against G3BP1 (green) or (b,d) FISH using oligo-dT probes (red). Nuclei were stained using DAPI (blue). Results are presented as the mean of three independent experiments ± SEM. Test: Anova two-way followed by Bonferroni post-hoc. Scale bar: 10 μm.
