Figure Lengend Snippet: (a) Relative expression of CDH1 and VIM mRNA in MCF7_miR200c_KO and DOX-treated MDA-MB-231_i-miR200c (MB231_i-miR200c) cells normalized to wild type (unmodified MCF7 or untreated MB231_i-miR220c, respectively). (b) Western blot of MB231_i-miR200c cells with and without doxycycline-induction stained for EMT-relevant marker CDH1, VIM and CD44s. (c) Whiskers plot showing alterations in C N -values (from 40× images) in MB231_i-miR200c cells with and without doxycycline-induction for growth on TACS5- and TACS6-like structures. One-way ANOVA with Bonferroni multiple comparison test was performed to calculate P-values at a 95 % confidence interval (n (cells) > 50). (d) Corresponding confocal images of (c) at 10× magnification. Cells were stained for nuclei (blue) and the cytoskeleton (red). Comparison of trajectory analysis of (e) WT cells with MCF7_KO or (f) MB231_i-miR200c, respectively, performed with Fiji software (TrackMate). Displacement, mean migration speed, confinement ration and mean directional change were plotted as whiskers plot (5–95 percentiles). Statistical significance was assessed with a t -test based on > 150 cells/condition. Stars indicate statistical significance (∗∗∗P < 0.001; ∗∗P < 0.01; ∗P < 0.05, ns = not significant).

Figure Lengend Snippet: A – C Kaplan–Meier survival curves for patients with glioma from the TCGA, CGGA, and REMBRANDT datasets, stratified by high and low expression of P4HB . P -values were calculated using the log-rank test and Wilcoxon test. D UMAP plot showing the clustering of different cell types within the GBM patients’ tissues, and the expression levels of P4HB across different cell clusters. E – G Relative mRNA expression levels of P4HB in X01, 448, and 83 GSCs, respectively, were measured by qRT-PCR after shRNA-mediated knockdown of P4HB . Data are presented as means ± SD, n = 3, *** P < 0.001, t-test. H Western blot analysis of P4HB, NESTIN, and SOX2 protein levels in X01 GSCs after shRNA-mediated knockdown of P4HB , α-tubulin was used as a loading control. I Limit-dilution assay for sphere-forming capacity in X01 GSCs following shRNA-mediated knockdown of P4HB . Log fraction without spheres is plotted against the number of initial cells per well. ** P < 0.01, *** P < 0.001, t-test. J Western blot analysis of P4HB, NESTIN, and SOX2 protein levels in 448 GSCs after shRNA-mediated knockdown of P4HB , α-tubulin was used as a loading control. K Limiting dilution assay for sphere-forming capacity in 448 GSCs following shRNA-mediated knockdown of P4HB . ** P < 0.01, *** P < 0.001, t-test. L Western blot analysis of P4HB, NESTIN, and CD44 protein levels in 83 GSCs after shRNA-mediated knockdown of P4HB , α-tubulin was used as a loading control. M Limiting dilution assay for sphere-forming capacity in 83 GSCs following shRNA-mediated knockdown of P4HB . ** P < 0.01, *** P < 0.001, t-test.
