Expression ratio of genes in GLAO group. Supplementation of GLAO had no significant effects on gene expression of EGFR, FABP7, PPAR-γ and RXR-α relative to SFO group. Log2 scale of expression ratios and singnificancy were calculated by REST, using beta-actin and GAPDH as reference genes and tumor samples of SFO group as control group and amplification efficiencies were considered in the analysis. Each value is mean ± S.E. of eighteen determination performed on separate animals.
