Fig. 4. Metabolic genes correlate expression. Correlations between the expressions of two enzymes; green boxes are significant positive correlations, blue is negative, and yellow is a lack of correlation. Correlation among (A) all metabolic genes; (B) oxidative phosphorylation genes; (C) glycolytic genes and (D) TCA genes. These are symmetric matrices, thus the order of genes across the top is the same as on the left side. Gene names are not given in A and B because of size constraints.
