Abstract

Dysregulated metabolism is a hallmark of cancer cell lines, but little is known about the fate of glucose and other nutrients in tumors growing in their native microenvironment. To study tumor metabolism in vivo, we used an orthotopic mouse model of primary human glioblastoma (GBM). We infused (13)C-labeled nutrients into mice bearing three independent GBM lines, each with a distinct set of mutations. All three lines displayed glycolysis, as expected for aggressive tumors. They also displayed unexpected metabolic complexity, oxidizing glucose via pyruvate dehydrogenase and the citric acid cycle, and using glucose to supply anaplerosis and other biosynthetic activities. Comparing the tumors to surrounding brain revealed obvious metabolic differences, notably the accumulation of a large glutamine pool within the tumors. Many of these same activities were conserved in cells cultured ex vivo from the tumors. Thus GBM cells utilize mitochondrial glucose oxidation during aggressive tumor growth in vivo.

  • Evidence for the necessity of glutamine for cancer progression is conflicted: some studies report tumours can grow well without glutamine, while others show cancers are glutamine-addicted.

    “The evidence for the necessity of glutamine for cancer progression is conflicted: some studies have reported that tumours can grow well without glutamine [66,67], while others showed that cancers are glutamine-addicted [68,69,70].”

    From HIF-1-Independent Mechanisms Regulating Metabolic Adaptation in Hypoxic Cancer Cells (2021) · cites this paper as [66]

    The Results (‘Glutamine independence of cells derived from orthotopic GBMs’; page unavailable) show that tumor-derived neurospheres survived and grew without extracellular glutamine, but describe their growth as ‘at least a low rate,’ not growing well. The Discussion (page unavailable) also reports that the tumors synthesized and accumulated glutamine, so the finding is independence from an external supply, not growth without glutamine itself. The citation is attached to the glutamine-independent side of the citing sentence, not the glutamine-addicted side. (LLM, conf=0.87)

  • Cancer tissue-of-origin has served as a successful way to select patients for chemotherapies targeting metabolism for decades, and environment can influence the efficacy of drugs targeting DHODH, mitochondrial complex I, and glutaminase.

    “Cancer tissue-of-origin has served as a successful way to select patients for chemotherapies targeting metabolism for decades, and environment can also influence the efficacy of drugs targeting DHODH, mitochondrial complex I, and glutaminase (Davidson et al., 2016; Gui et al., 2016; Marin-Valencia et al., 2012; Sellers et al., 2015; Sykes et al., 2016; Tardito et al., 2015).”

  • Glutamine tracing studies have demonstrated that in some tumor tissues glutamine contributes minimally to TCA cycle intermediates, and those cancers can be resistant to glutaminase inhibition.

    “Glutamine tracing studies have demonstrated that in some tumor tissues, glutamine contributes minimally to TCA cycle intermediates, and those cancers can be resistant to glutaminase inhibition (Davidson et al., 2016; Hensley et al., 2016; Marin-Valencia et al., 2012; Sellers et al., 2015; Tardito et al., 2015).”

    From Targeting Metabolism for Cancer Therapy (2017) · cites this paper as Marin-Valencia et al., 2012

  • A prior in vivo study using 13C-labeled glucose and glutamine tracers showed patient-derived xenografts from primary GBMs consume glutamine but do not readily convert it to glutamate; instead they oxidize glucose to make glutamate.

    “A prior in vivo study using 13C-labeled glucose and glutamine tracers showed that patient-derived xenografts made from primary GBMs, ~95% of which are IDH wild-type, consume glutamine, but do not readily convert it to glutamate (Marin-Valencia et al., 2012).”
  • Isotope tracing studies in lung and glioblastoma tumors suggest that glutamine is a relatively minor source of TCA cycle carbon in some cancer cells growing in vivo.

    “However, isotope tracing studies in both lung and glioblastoma tumors suggest that glutamine is a relatively minor source of TCA cycle carbon in some cancer cells growing in vivo, indicating that environmental context can drive fuel preferences (193, 194).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
