The Antitumor Effect of Curcumin in Urothelial Cancer Cells Is Enhanced by Light Exposure In Vitro

Figure 1

Growth of RT112, UMUC3, and TCCSUP cells treated with curcumin alone or with curcumin plus visible light. Cells were incubated in 96-well-plates for 24, 48, and 72 h. Controls remained untreated. Cell number was set to 100% after 24 h incubation. Bars indicate standard deviation (SD). indicates significant difference to untreated controls, p ≤ 0.05.
