Figure Lengend Snippet: PPOX knockdown inhibits the migratory and invasive capacities of ccRCC cells and downregulates Wnt/β-catenin signaling pathway activity. (A) Wound healing assay confirmed that PPOX knockdown inhibited cell migration (magnification, 40×). (B) Transwell assay confirmed that PPOX knockdown inhibited cell invasion (stained with crystal violet; magnification, 100×). (C) PPOX knockdown reduced Wnt/β-catenin pathway activity. All experiments were performed with at least three independent replicates. Statistical comparisons between two groups were analyzed by unpaired Student’s t-test using GraphPad Prism 8. Scale bar: 100 μm. NC, negative control; PPOX, protoporphyrinogen oxidase.

Figure Lengend Snippet: PPOX overexpression enhances the proliferative, migratory, and invasive capacities of ccRCC cells and upregulates Wnt/β-catenin pathway activity. (A) PPOX overexpression efficiency in A498 and 769-P cells. (B-D) CCK-8, colony formation, and EdU assays (EdU and DAPI staining; magnification, 100×) confirmed that cell proliferation was elevated after PPOX overexpression. (E,F) Wound healing (40×) and Transwell assays (stained with crystal violet; magnification, 100×) confirmed that PPOX overexpression enhances cell migration and invasion. (G) PPOX overexpression enhanced Wnt/β-catenin pathway activity. All experiments were performed with at least three independent replicates. Statistical comparisons between two groups were analyzed by unpaired Student’s t-test using GraphPad Prism 8. Scale bar: 100 μm. NC, negative control; OD, optical density; OE, overexpression; PPOX, protoporphyrinogen oxidase.

(C) Cell proliferation assessed by EdU assays (magnification, 100×) under PPOX knockdown and CHIR-99021 treatment. (D) Cell migration evaluated by wound healing assays (magnification, 40×). (E) Cell invasion analyzed by Transwell assays (stained with crystal violet; magnification, 100×). All experiments were performed with at least three independent replicates. Two-group comparisons were analyzed using the unpaired t-test, whilst multiple groups (>2) were compared using one-way ANOVA, followed by Tukey’s HSD test for post hoc pairwise comparisons where applicable. Scale bar: 100 μm. ANOVA, analysis of variance; ccRCC, clear cell renal cell carcinoma; HSD, Honestly Significant Difference; NC, negative control; PPOX, protoporphyrinogen oxidase.

Article Title: Effects of SOX10 on the proliferative, invasive, migratory, and epithelial–mesenchymal transition abilities of triple-negative breast cancer cells

doi: 10.3389/fonc.2026.1769833

Figure Lengend Snippet: Effect of SOX10 knockdown and overexpression on classical Wnt/β-catenin pathway-related protein expression in TNBC cell lines. Protein expression of C-myc, CyclinD1, WNT1, phospho-GSK-3β (Ser9), and nuclear β-catenin was detected by Western blot analysis, with band gray values normalized to GAPDH (total protein) or Lamin B1 (nuclear protein, for β-catenin). (A) Protein expression and quantification in MDA-MB-453 cells. (B) Protein expression and quantification in HCC1937 cells. All experiments were independently repeated three times (n = 3 independent biological replicates), and representative results are shown. Statistical analysis was performed using unpaired two-tailed Student’s t-test for two-group comparisons. siSOX10 vs. siNC, ** P < 0.01; SOX10-OEvs. NC, ## P < 0.01. && indicates P<0.01; $$ indicates P<0.01 for statistical comparisons.
