Tumor growth (mean ± SEM) in mice treated with CP and human DNA, comparing the regimen shown below with the control (n = 10). Mice received two CP injections (100 mg per 1 kg body weight) on a daily interval; 0.5–1 mg human DNA were administered i.p. or s.c. to the mice. The control group was injected with saline. Krebs-2 tumor cells were grafted i.m. 1.5 month after the last DNA administration. The other group (2) received four human DNA s.c. injections after the tumor grafting. And the last group (3) didn't received CP but only four administrations of exogenous DNA preparations after the tumor grafting.
