Figure 5. Curcumin inhibits liver metastasis of GC through CXCR4. (A) Cultured PGCs were treated with/without 0.5µmol/l Curcumin for 12 hours and then stained for CXCR4. (B) CXCR4 levels were also assessed in the formed tumor by s.c. PGC grafting in mice that had received Curcumin or control, by immunostaining (B), and by Western blotting (C). *p<0.05. N=30. Scale bars are 50µm.
