a A scheme of treatment in an HT-1080 xenograft tumor model with IKE. Athymic nude mice were injected subcutaneously with indicated ALDH1B1-knockdown (ALDH1B1KD) or EIF4E-knockdown (EIF4EKD) HT-1080 cells for 7 days and then treated with IKE (40 mg/kg, i.p., once every other day) at day 7 for 2 weeks. b Tumor volumes were calculated weekly (n = 6 mice/group; two-way ANOVA with Tukey’s multiple comparisons test; data are presented as mean ± SD). c Photographs of isolated tumors on day 14 after treatment. di The levels of 4HNE (d) and PTGS2 mRNA (e) in isolated tumors, serum HMGB1 (f), caspase-3 activity (g), ALDH1B1 protein (h), and EIF4E protein (i) in isolated tumors at day 14 after treatment were assayed (n = 6 mice/group; two-way ANOVA with Tukey’s multiple comparisons test; data were presented as mean ± SD).
