Figure 5From: Altered regulation of metabolic pathways in human lung cancer discerned by 13C stable isotope-resolved metabolomics (SIRM)Relationships between Krebs cycle intermediates and glycolytic products in terms of 13C-labeled and total concentrations for lung tumor and non-cancerous tissues resected from patients #6–10. Metabolite and 13C isotopomer concentrations ([metabolite]) were determined from GC-MS analysis as described in Methods. The R2 of the linear fit (solid red lines for cancer and dash black lines for non-cancerous tissues) for these plots are listed in Table 4.Back to article page
