Effects of sesamin on SP cells-derived tumor growth in vivo . After pretreated with sesamin (100 μM) for 7 days, 1 × 105 SP cells from both SGC-996 and GBC-SD were injected subcutaneously into 6-week-old nude mice (n = 6 each group). Tumor volumes were measured weekly. *p < 0.05 vs. control group. Ses: sesamin.
