Figure 5From: The oxysterol 27-hydroxycholesterol increases β-amyloid and oxidative stress in retinal pigment epithelial cells 27-OHC effects on glutathione, ROS and HO-1. Treatment with 27-OHC causes a decrease in glutathione concentrations (a), an increase in ROS generation as measured by DCFH-DA assay (b) and an increase in HO-1 levels (c). *p < 0.05, **p < 0.01 vs control.Back to article page
