Radical Scavenging Activity-Based and AP-1-Targeted Anti-Inflammatory Effects of Lutein in Macrophage-Like and Skin Keratinocytic Cells

Figure 4

The scavenging effect of lutein on the generation of radicals and ROS in UV-irradiated HaCaT cells. (a) The radical scavenging activity of lutein was determined by measuring the levels of NO. released from SNP (20 mM) in the presence or absence of lutein. (b) Immediately after UVA exposure, ROS production was quantified by measuring the fluorescence from the oxidation product of carboxy-H2DCF-DA, as described in Section 2. and compared to the control.
