Figure 6.

Effect of DPI and of H₂O₂ generated by GOG on PAL activity. PAL activity from treated and control (C) cells was measured after 8 h of incubation. Bars represent the means ± sd of two independent experiments. A, Cells treated with 50 nm β-megaspermin (beta), 10 μm DPI (DPI), or both (beta+DPI). B, Cells treated with 0.5 nm (beta 0.5) or 50 nm (beta 50) β-megaspermin, 5 units/mL Glc oxidase and 5 mm Glc (GOG), or 0.5 nm β-megaspermin and 5 units/mL Glc oxidase and 5 mm Glc (beta 0.5+GOG).
