Figure Lengend Snippet: The PDPK1/AKT/FLT DPI and tenovin-6 (T6) show high anti-cancer efficacy in murine tumoroids and human PCa cell lines (A) Dose-response curves for DPI (top) and T6 (bottom) for in vivo and in vitro Pten KO (left), Pten/Stat3 KO (middle), and Pten/Tp53 KO (right) tumoroids. Points represent means of technical duplicates per tumoroid line ( N = 3). Curve fitting was performed using GraphPad Prism 8.0.2. (B) Bar graphs showing means and ±SD of half-maximal inhibitory concentration (IC50) for DPI (top) and T6 (bottom) for in vivo and in vitro tumoroid lines of all genotypes ( N = 3). Statistical analysis was performed using GraphPad Prism 8.0.2 (one-way ANOVA, Tukey’s test). p > 0.05 if not specified otherwise, ∗ p ≤ 0.05. (C) Bar graphs depicting means and ±SD of IC50 values of DPI (left) and T6 (right) on human PCa cell lines. 22RV1: primary PCa; LNCaP: metastatic PCa; DU145, PC3: metastatic castration-resistant PCa ( N = 3). Statistical analysis was performed using GraphPad Prism 8.0.2 (one-way ANOVA). p > 0.05 if not specified otherwise, ∗ p ≤ 0.05; ∗∗ p ≤ 0.01. (D) Heatmaps of synergy scores calculated with the highest single agent (HSA) model for DPI and enzalutamide (left), and T6 and enzalutamide (right) on the human LNCaP cell line. Values > 0 represent synergistic effects, and values < 0 represent antagonistic effects. IC50 concentrations of respective compounds are underlined ( N = 3). See also .
