miR-890 mimetic injection enhances IR therapy of established prostate tumors. (A) Established subcutaneous DU145 tumors (n = 3–5 per group) were directly injected with PBS or miRNA mimetics in neutral lipid emulsions. Two days after injection (day 0) tumors were irradiated with 6 Gy or no IR. miR-890 significantly reduced tumor volume in irradiated groups when compared to controls. ***P < 0.001, **P < 0.01, *P < 0.05; two-way ANOVA. Mean ± SEM. (B) Extension of tumor quadrupling for DU145 tumor model. Events (animals whose tumor volume was not yet 4-fold the size at injection) were plotted by Kaplan-Meier curve. miR-890 significantly extended time to tumor quadrupling in irradiated groups when compared to controls. P < 0.01; log-rank (Mantel-Cox) test.
