Image data for effect of IPZ on the nucleus/cytoplasm localization, SG formation of hnRNP A1, HuR and TIA1 during arsenite-induced oxidative stress. HeLa cells were cultured and transiently transfected with plasmids of RFP-hnRNP A1 (A), RFP-HuR (B), RFP (C), GFP-TIA1 (D), and GFP (E), respectively, as indicated. After the pretreated with 10 μM IPZ for 6 hours [IPZ (+)] or not [IPZ(-)], cells were treated with 0.5 mM sodium arsenite for 1 hour. The nuclenus section was stained by DAPI. An Inverted research microscope Leica was then used to collect the image data. Bar=10 μm.
