Figure 3From: Enhanced production of nitric oxide, reactive oxygen species, and pro-inflammatory cytokines in very long chain saturated fatty acid-accumulated macrophagesIntracellular ROS productions in macrophages. Cells were incubated with 10 μM of DCFH-DA for 15 min, and then stimulated with 0.5 μg/ml of PMA for 20 min at 37°C. Fluorescence of DCF was measured by a flow cytometer as described in Methods. Values are mean-fold increase of relative DCF fluorescence intensity compared with non-stimulated control and expressed as mean ± SD, n = 6. * P < 0.05 for comparison with wild-type.Back to article page
