Fig. 2: Differential expression of the metabolic genes in tumor samples compared to the matched and non-matched control.

The heat maps represent the logarithmic values of the expression levels of the different metabolic genes. A The fold change of the expression of each of the genes were represented in the heat maps. A set of 11 carbohydrate, 5 amino acid, and 6 lipid metabolism genes were examined. B–D The logarithmic values of the fold change of expression of all the genes of carbohydrate, amino acid, and fatty acid metabolism for each of the groups i.e., tumor, matched control, and non-matched control were represented as bars and are compared among themselves. The real-time PCR experiments were performed in duplicates, with two experimental repeats for each gene. *P < 0.05; **P < 0.005; ***P < 0.001.
