Figure Lengend Snippet: Effects of compound 3b and 4b in migration, cell cycle progression, and MDA accumulation in PCa cells. (a) Representative images of DU145 cells migration upon scratch generation in a confluent monolayer. Time point 0 h (T = 0 h) or 60 h (T = 60 h) points post-incubation in presence of DMSO, compound 3b or compound 4b at 20 µM final concentration, are shown. Scale bar = 100 µm. (b) Quantification of scratch area reduction over time normalised to the scratch area at T = 0 h. Wound healing was monitored at 12, 24, 36, 48 and 60 h post-incubation with the indicated compounds. (c) Quantification of cell cycle distribution in DU145 cells treated with DMSO, compound 3b or compound 4b at 20 µM final concentration for 24 h prior to cytofluorimetric analysis. The percentage of cells in each population is shown. (d) Total intracellular ALDH activity measured in DU145 cell lysates following pre-incubation with 20 µM 3b or 4b for 24 h at 37 °C. Cells were extensively washed prior to lysis to eliminate any non-covalently bound material. (e) Quantification of malondialdehyde (MDA) levels in the same cell lysates. MDA concentration was measured and normalised to the total protein content of each sample, as determined by the Bradford assay. In all plots, error bars represent the standard deviation, and asterisks indicate statistical significance levels: p ≤ 0.05 (*), p ≤ 0.01 (**), and p ≤ 0.001 (***).

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 .
