Figure 10. Inhibition of THBS2 affects the proliferation and migration of PCa cells in vitro. (A) The expression of THBS2 in TCGA PCa tumor tissues (n = 492) and the normal (n = 52). (B) Protein expression of THBS2 in the normal prostate epithelial cell line (RWPE-1) and PCa cell lines (C4-2B, DU145, C4-2 and PC-3). (C) Western blotting showing THBS2 siRNA knockdown compared to control siRNA treatment. (D) CCK-8 assay showed that THBS2 knockdown inhibited C4-2 and PC-3 cell proliferation. (E) The colony formation assay showed that THBS2 knockdown inhibited C4-2 and PC-3 colony formation. The graph on the right shows the colony numbers from 3 independent experiments. (F) Transwell assays showed that THBS2 knockdown inhibited C4-2 and PC-3 cell migration (Scale bar, 50 μm). The graph on the right shows the migrated cells from 3 independent experiments. All data are presented as the mean ± SD, *p < 0.05, **p < 0.01, ***p < 0.001.
