IL27 and neoplasm: In mice bearing IL30-overproducing PCs, treatment with IL30-targeting immunoliposomes consistently slowed tumor growth compared to that in mice bearing IL-30-TRAMP-C1 tumors, treated with empty-mPSCA NxPs or PBS, and mice bearing wild-type TRAMP-C1 tumors treated with PBS (ANOVA: p < 0.0001) (Fig. 8i).
