a Mice were injected in the scrotal sac with 1 × 106 PC-3ML cells. Treatment was initiated at day 28, and mice treated with (▲) 4 ug/biw DNAZYM-1P) (n = 50); (◆) scrambled oligonucleotide (n = 30); (Ж) vehicle (n = 20) or (○) untreated. The agent was injected in the scotal sac in 0.1 ml buffer. Tumor size was measured with calipers at 2 week intervals. 5b. Mice (n = 30/agent) were injected i.v. via the tail vein at day 1 and day 10 with 1 × 105 cells/ml (in 0.1 ml) then treatment started after 2 weeks by i.v. injection via the tail vein weekly of (◆) scrambled oligonucleotide, (○) vehicle, (Ж) buffer, and (▲) DNAZYM-1P. Tumor volume was measured in 2 mice at 2 weeks by sacrificing a few mice for measurements and then at the time of sacrifice following treatment of mice for 1, 2, 3 and 4 mos. 5c. Mice were injected with tumor cells according to methods in fig. 5b and treated with either (◆) 4 ug/ml, (■) 3 ug/ml and (●) 2 ug/ml biw DNAZYM-1P. Control mice were treated with (▲) lipofectamine and (Ж) scrambled oligonucleotide. Mice were treated for 2 mos, then treatment was discontinued for up to 17 weeks. 5d–5e. H&E and RPS2 antibody immunolabeled sections of a tumor from a mouse treated with the scrambled oligonucleotide for 2 mos (see fig. 5c).
