Expression profiles of top gene sets associated with individual supplementation of folate-dependent metabolites. Heatmap of gene set scores for top gene sets associated with individual factors. Blue and yellow color refers to down-regulation and up-regulation of gene sets respectively. Colored triangles above the heatmap indicate time progression from 10 min to 120 min after the beginning of drug treatment. The figure is split into vertical panels A-E according to the condition and into horizontal strips according to the gene set.
