Therapeutic effect of CEA-SARS-derived epitopes on tumor establishment. BALB/c mice were inoculated with CT26/CEA cells on day 0. Four days later, the mice were fed with pCEA- and pCEA-SARS-transformed S. typhimurium once per week (5 mice/group), and the subsequent tumor volume in the mice was observed. (*, p < 0.05 in comparison with the control and the pCEA group).
