DHA exhibits anti-tumor effects in colon cancer cells. (A) Viabilities of HCT116 and RKO cells treated with various concentrations of DHA at different times. (B) Expression levels of apoptosis-associated proteins in HCT116 and RKO cell lines treated with DHA. (C) Flow cytometric analysis of apoptosis in HCT116 and RKO cell lines treated with DHA and Z-VAD-FMK. (D) The percentage of apoptotic cells was measured. Data are presented as mean ± SD. * p < 0.05, ** p < 0.01, *** p < 0.001. All experiments were repeated three times.
