TNKS knockdown and DHA inactivate the Wnt/β-catenin pathway in gastric cancer. (A) Immunofluorescence analysis of TNKS, AXIN2 and β-catenin in HGC-27 and AGS gastric cancer cells treated with si-TNKS1/si-TNKS2, HLY78, DHA and HLY78 + HLY78. (B) TNKS, (C) AXIN2 and (D) β-catenin expression levels were quantified for HGC-27 cells. (E) TNKS, (F) AXIN2 and (G) β-catenin expression levels were quantified for AGS cells. *P<0.05, **P<0.01, ***P<0.001 and ****P<0.0001 vs. the si-NC group; ##P<0.01, ###P<0.001 and ####P<0.0001 vs. the control group; &&&&P<0.0001 vs. the HLY78 group. TNKS, Tankyrases; DHA, Dihydroartemisinin; si, small interfering; NS, negative control.
