Figure 6From: Replicase-based plasmid DNA shows anti-tumor activity Injection with pSIN-β promoted more tumor cells to undergo apoptosis. (A). Micrographs of tumors stained against anti-caspase-3 (brown). (B). Apoptotic index. Data shown were mean ± S.E.M. The number of mice in each group was 3-4. (*) Indicates that the value of pSIN-β differed from that of the others (ANOVA, p = 0.03).Back to article page
