NSG and BALB/c mice were subcutaneously injected with HCT116 cells and CT26 cells, respectively. Mice were fed ad libitum or subjected to FMD cycles, and treated with or without vitamin C or oxaliplatin (10 mg/kg). a HCT116 tumor progression (left) and volume at day 33 and 36 (right), respectively (n = 10 in Ad libitum, FMD, FMD + Vit C, Vit C + OXP, FMD + Vit C + OXP, n = 8 in FMD + OXP, n = 9 in OXP, n = 11 in Vit C). P values were determined by One-way ANOVA with Tukey’s post analysis (day 33) and two-sided unpaired t-test (day 36). Data are represented as mean ± SEM. b BALB/c with CT26 survival curves (n = 9 in Ad libitum, n = 10 in OXP, n = 12 in FMD + OXP and FMD + OXP + Vit C, n = 14 in OXP + Vit C and FMD + Vit C). P values were determined by Log-rank (Mantel-Cox) test (Ad libitum vs OXP, p = 0.0040; OXP vs FMD + Vit C, p = 0.7177; OXP vs FMD + OXP + VitC, p = 0.0114; FMD + OXP vs FMD + OXP + Vit C, p = 0.0488; OXP + Vit C vs FMD + OXP + Vit C, p = 0.0345; FMD + OXP + Vit C vs FMD + Vit C, p = 0.0003).
