Induction of apoptosis by curcumin. Flow cytometric analyses of the cell lines FTC-133, BHT-101 and TPC-1 display an increased proportion of Annexin V+ and PI + cells after exposure to 50 µM curcumin for 16 h. One representative example for FTC-133 cells is displayed in a. To illustrate the autofluorescent cell signal after curcumin treatment, a condition without the addition of Annexin V or PI was added (right dotplot). A diagram summarizing all three independent biological replicates are displayed in b. Statistical significance is indicated; *p < 0.05
