Figure 4. Impact of PCMT1 inhibition on the migration and invasion of PCa cell lines. (A) Effect of PCMT1 inhibition on PCa cell migration measured by wound-healing assay (×40). (B) PCa cell migration ability was assessed by a transwell migration assay (×200). (C) PCa cell invasion ability was examined by a transwell invasion assay (×200). Data are expressed as mean ± SD of at least three experiments. *P < 0.05, **P < 0.01, ***P < 0.001.
