Fig. 1: Unbiased metabolomics identified TFEB regulation of hepatic sulfur amino acid metabolism pathways.

Male 10 weeks old C57BL/6 J mice were intravenously injected with Ad-Null or Ad-TFEB at 5 × 108 pfu/mouse. One week later, mice were fed chow (C) or Western diet (WD) for one additional week. Mice were fasted for 6 h and euthanized for tissue collection. Liver tissues were used for global metabolomics and bioinformatics analysis as described in the Method section (n = 4). a Heatmap of hierarchical clustering analysis. b Principal component analysis. c Number of upregulated or downregulated metabolites by TFEB overexpression independent of dietary conditions. d, e Over-represented pathways. A * indicates pathways of interest that were further investigated in this study.
