Effect of immunization with pCMV ECDTM plasmid on tumor incidence (left) or mean tumor diameter (right) in young and old Balb/c mice challenged with syngeneic TUBO cells. Young and old mice received two immunizations with pCMV ECDTM DNA plasmid or with pCMV and, 2 weeks ago, were challenged with TUBO cells. Eight mice for each group were used for each experiment. Data shown are representative of one of the two independent experiments
