Figure 3From: The oxysterol 27-hydroxycholesterol increases β-amyloid and oxidative stress in retinal pigment epithelial cells 27-OHC activated ER stress. Western blots showing an increase in levels of caspase 12 (a) and gadd153 (b), two specific markers of ER stress. (c) Immunocytochemistry shows that gadd153 immunorectivity (green) is localized in nucleus (DAPI, blue) following treatment with 27-OHC (arrows). *p < 0.05, **p < 0.01 vs control; Bar, 20 μm.Back to article page
