Effect of DHA on apoptosis induction. 5 × 105 HCT-116 cells per well were treated with various concentrations of DHA for 48 h, after which apoptosis was measured using flowcytometer. a FL1: Annexin V-FITC (horizontal axis) and FL2: PI (vertical axis). (Q1) pre-necrotic cells, (Q2) late apoptosis, (Q3) live cells, and (Q4) early apoptotic cells. b Histogram presentation of apoptotic cell percentages *P < 0.05, **P < 0.01, and ***P < 0.001 vs. untreated control cells (C)
