Effect of DHA on caspase-3 activation. 5 × 105 HCT-116 cells were treated with various concentrations of DHA for 48 h after which caspase-3 activity was measured in tumor cell lysates using colorimetric assay. All experiments were repeated twice using triplicate assays and results were presented as mean ± SD. ***P < 0.001 vs. untreated control cells (C)
