Dietary Phenolic Acids Act as Effective Antioxidants in Membrane Models and in Cultured Cells, Exhibiting Proapoptotic Effects in Leukaemia Cells
Figure 5
Effect of phenolic compounds on basal ROS levels in HEL cells and HUVEC. Cells were treated with different compounds (5 or 10 μM for HEL cells, (a); 20 μM for HUVEC, (b)) for 20 hours, then ROS levels were measured by means of H2DCFDA assay as described in Section 2. Results are expressed as means ± SD of four independent experiments, each performed in octuplicate. , significantly different from control cells; , significantly different from control cells.
