Proliferation of NPC-TW01 cells transfected with β-catenin (A) siRNA or (B) overexpression plasmids. NPC-TW01 cells in siR-NC and siR-CLDN1 groups were transfected with siR-NC and siR-β-catenin (rescue group), respectively. NPC-TW01 cells in the NC and CLDN1 groups were transfected with pcDNA3.1-NC and pcDNA3.1-β-Catenin (rescue group), respectively. A Cell Counting Kit-8 assay was used to measure proliferation at absorbance at 450 nm and proliferation curves were then plotted. *P<0.05 vs. the respective NC. si, small interfering; NC, negative control.
