To access the data, click or select the words “Appendix 2.” After MG132 treatment (final conc.=5 µM), cells were observed under a fluorescence microscope. Here the images of WT-EPHA2 overexpressing cells were presented (all the other types of EPHA2 overexpressing cells showed similar changes of cell death). The upper lanes, bright light images; lower lanes, fluorescent images. Scale bar, 200 µm.
