Treatment of WT U-2 OS cells with arsenite showed a highly significant and global shortening of RNA upon stress (Mann–Whitney, p-value<10 –307 ) in stark contrast to ΔΔG3BP1/2 cells that showed substantially less shortening (Mann–Whitney, p-value<10 –5 ) ( Figure 6e , Figure 6—figure supplement 1g and h ).
