C: Control; CG: Control supplemented with L-glutamine, WT: Walker 256 tumor; WTG: Walker 256 tumor supplemented with L-glutamine. Averages with different pairs of capital letters on the same line (A-B; C-D) show comparisons between control (C x WT) and supplemented groups (CG x WTG), respectively. Averages with different pairs of lower case letters on the same line (a-b; c-d) show comparisons between control (C x CG) and Walker Tumor groups (WT x WTG), respectively. Data are expressed as mean ± standard deviation of the mean (p≤0.05).
