Identification of Novel Stress Granule Components That Are Involved in Nuclear Transport
Figure 4
Importin-β1, but not CAS, binds to SGs in response to oxidative stress.
HeLa cells treated with DEM or arsenite were stained with antibodies against the carrier importin-β1 or CAS. Co-staining was performed with the SG marker HuR; nuclei were detected with DAPI. Size bar is 20 µm; SG-containing areas (white squares) are magnified 500×.
