The Indolic Diet-Derivative, 3,3′-Diindolylmethane, Induced Apoptosis in Human Colon Cancer Cells through Upregulation of NDRG1

Figure 1

Effect of DIM on cell viability. Exponentially growing cells were incubated in the presence of 10 to 100 μM of DIM for 72 hours, and the viable cells were detected by XTT assay. The results are presented as percentage of control and expressed as means ± SD of three independent experiments.
