Coordinate recruitment of poly(A)+
RNA, PABP-I, eIF4E, and HuR to SGs during SG assembly and disassembly.
DU145 cells were arsenite-stressed and allowed to recover as in Figure
5. Top left, TIA-1 (green) versus poly(A) (red); bottom left, TIA-1
(green), PABP (red); Top right, TIA-1 (green), eIF4E (red); bottom
right, TIA-1(green), HuR (red). In all panels, blue represents DNA
(Hoechst staining). Bar, 20 μm. Merged views are shown in the right
panels of each series. Arrows indicate SGs in each view.
