Figure 2.

Analysis of tumor cell proliferation. RT112, UMUC3, and TCCSUP cells were exposed to 0.1 or 0.4 μg/ml curcumin alone or with curcumin plus visible light. Controls received cell culture medium alone. BrdU incorporation was evaluated after 24 h or 48 h. The figure depicts relative fluorescence values (RFU). Bars indicate standard deviation (SD). ∗ indicates significant difference to control, p ≤ 0.05.
