Figure 2. Metabolic rewiring in lung tumours from KrasG12D/+; p53-/- mice.
Schematic representation of metabolic networks in lung tumours from KrasG12D/+;p53-/- mice based on in vivo flux/tracing analyses. Enhanced flux from different labelled substrates is shown as indicated, with orange depicting glucose metabolism (based on 13C-Glucose [21, 57]); green: amino acid metabolism (13C-Leucine/Valine; solid), 15N-Leucine; dashed [25]); and purple: fatty acid metabolism (2H2O [62]). Grey arrow depicts similar flux relative to normal tissue [57]. Slc2a1, Glucose transporter 1; Acc, Acetyl-Co A carboxylase; Gcs, glutamylcysteine synthetase; Pdh, pyruvate dehydrogenase; Pc, pyruvate carboxylase.
