Fig. 7. ICIE effectively inhibits tumor growth in both primary and distant tumors with no evident systemic toxicity.

Fig. 7

a Tumor growth curve of left-side tumors including primary (P) tumors from mice with cryosurgery and left (L) tumors from mice without cryosurgery (n = 6 mice). The mice were also injected with one of the formulations including: PBS, free CPT&siR, CPT CRNPs, siR CRNPs, or CPT&siR CRNPs. b Tumor growth curve of right-side tumors including distant (D) tumors from mice with cryosurgery on P tumors and right (R) tumors from mice without cryosurgery (n = 6 mice). The mice were also injected with one of the indicated formulations. c, d Weight of left-side (L versus P, c) and right-side (R versus D, d) tumors (n = 6 mice) obtained after sacrificing the mice at the end of the study, showing effective tumor destruction by the ICIE treatment. e Representative hematoxylin and eosin (H&E) staining images of left-side (L versus P) and right-side (R versus D) tumors, showing extensive necrosis in both the primary and distant tumors from mice with the ICIE treatment. The experiments were repeated three times independently (n = 3 mice) with similar results. Statistical analyses were done using two-way ANOVA with Sidak’s post-test and correction for multiple comparisons. Data are presented as mean ± SD (c, d).
