Effect of DHA on the p53 protein level. 5 × 105 HCT-116 cells per well were treated with different concentrations of DHA for 48 h, after which Wt-p53 protein levels in tumor cell lysates were measured by ELISA. All experiments were repeated twice using triplicate assays, and the results were presented as mean ± SD. *P < 0.05 and **p < 0.01 vs. untreated control cells (C)
