Figure 2.

Left panel: Morphologic alterations of DU145 and PC3 clones after curcumin (0.2 µg/mL), visible light (5 min at 1.65 J/cm²) or curcumin, and light exposure. Controls remained untreated. Pictures were taken after 7 days of incubation. Right panel: Influence of visible light (5 min at 1.65 J/cm²), curcumin (0.2 µg/mL), or curcumin–light combination on clonogenic growth, compared to untreated controls. Error bars indicate standard deviation; * indicates significant difference to untreated controls. n = 3.
