Detailed materials and methods are available online in the Supplemental Information. Briefly, Human lymphoma B P493 cells were grown in [U-13C]-labeled glucose or [U-13C,15N]-labeled glutamine for 24?hr. Nonhypoxic cells (21% [(vol/vol] O2) were maintained at 37��C in a 5% (vol/vol) CO2 and 95% (vol/vol) air incubator. Hypoxic cells (1% O2) were maintained in a controlled atmosphere chamber (PLAS-LABS) with a gas mixture containing [http://en.wikipedia.org/wiki/OPHN1 OPHN1] 1% O2, 5% (vol/vol) CO2, and 94% (vol/vol) N2 at 37��C for 48?hr. Metabolites were extracted from cells and media as previously described (Fan et?al., 2011). Bromobimane and carboxy-H2DCFDA were used to measure reduced glutathione ROS levels, respectively, using flow cytometry. ATP levels were determined by luciferin-luciferase-based assay (Promega). Cells treated with BPTES and/or tetracycline were then incubated with [3H] glutamine to assess glutaminase activity. The ��-oxidation of 14C labeled oleic acid was used to assess fatty acid oxidation. The presence of dead cells was determined by propidium iodide staining at 2?��g/ml using flow cytometry. Values are shown as mean?�� standard deviation (SD) or standard error of the mean (SEM). Data were analyzed using the Student's t test, and significance was defined as p?[http://www.selleckchem.com/products/ulixertinib-bvd-523-vrt752271.html BVD-523 datasheet] and Stand-Up-to-Cancer/American Association for Cancer Research translational grant (to C.V.D.); grants 1R01CA118434-01A2 and 3R01CA118434-02S1, University of Louisville CTSPGP grants 20044 (to?T.W.M.F.) and 20061 (to A.N.L.); and National Institutes of Health National Center for Research Resources (NIH NCRR) grant 5P20RR018733, Kentucky Challenge for Excellence, the Brown Foundation, and Kentucky Lung Cancer Research Program (postdoctoral fellowship to P.K.L.).

""Coordinate regulation of lipid metabolism is central to human health, and disruption of this process leads to a range of metabolic disorders, including obesity and cardiovascular disease. Normal lipid homeostasis is maintained by balancing dietary lipid uptake and synthesis with lipid catabolism and excretion.
