Carotenoids Inhibit Fructose-Induced Inflammatory Response in Human Endothelial Cells and Monocytes

Figure 7

Effects of β-cryptoxanthin, lutein, and lycopene on fructose-induced oxidative stress in ECs and monocytes. HUVECs or U937 cells were pretreated with β-cryptoxanthin, lutein, and lycopene (1 μM) or vehicle (control) for 2 h and then incubated with 2 mM fructose for 16 h. Lipid peroxidation was assessed by MDA content (a). (b) Determination of the intracellular ROS generation via DCFH-DA staining in fructose or carotenoid-treated HUVECs with a fluorescence microscope (lower panel) and quantitative intracellular DCF fluorescence (upper panel). The results are representatives of 3 fully independent experiments () and indicated as the percentage of fructose-stimulated cells. # vs. control; vs. fructose alone.
