Hierarchical cluster heatmap representing correlations of diclofenac glucuronide (DG) formation, protein abundance of UGT isoforms involved in DG formation (2B7, 2B4, 2B17, 1A3, and 1A9), and age in individual human intestinal microsomes (HIM, N=14; A) and pediatric hepatocytes (N=50; B). The correlations were evaluated by Pearson correlation analysis.
