Effect of curcumin on the cell viability of the 5-FU-stimulated IEC-6 cells. IEC-6 cells were stimulated with 5-FU for 24 h and then further treated with curcumin at 5, 10, and 20 μmol/L for 24 h or 48 h. CCK-8 assays were performed to detect the cell viability of each group cells. Data were expressed as mean ± standard error mean (SEM), ^▲▲p value < 0.01 vs. control group; ^∗p value < 0.05 vs. 5-FU group; ^∗∗p value < 0.01 vs. 5-FU group. 5-FU: 5-fluorouracil.
