Figure 1. APS inhibits the proliferation and migration of RT4 and T24 cells. CCK-8 assays revealed that APS significantly inhibited the viability of RT4 (A) and T24 (B) cells. The transwell results revealed that 15 and 10 μM APS significantly inhibited the migration of RT4 (C) and T24 (D) cells (Bar represents 10 μm, 20 × magnification). Scratch assays confirmed that 15 and 10 μM APS significantly reduced the migration of RT4 (E) and T24 (F) cells (Bar represents 50 μm, 4 × magnification). *p < 0.05, **p < 0.01 vs. Con.
