Abstract

The oncometabolite 2-hydroxyglutarate (2-HG) is a signature biomarker in various cancers, where it accumulates as a result of mutations in isocitrate dehydrogenase (IDH). The metabolic source of 2-HG, in a wide variety of cancers, dictates both its generation and also potential therapeutic strategies, but this remains difficult to access in vivo. Here, utilizing patient-derived chondrosarcoma cells harboring endogenous mutations in IDH1 and IDH2, we report that 2-HG can be rapidly generated from glutamine in vitro. Then, using hyperpolarized magnetic resonance imaging (HP-MRI), we demonstrate that in vivo HP [1-13 C] glutamine can be used to non-invasively measure glutamine-derived HP 2-HG production. This can be readily modulated utilizing a selective IDH1 inhibitor, opening the door to targeting glutamine-derived 2-HG therapeutically. Rapid rates of HP 2-HG generation in vivo further demonstrate that, in a context-dependent manner, glutamine can be a primary carbon source for 2-HG production in mutant IDH tumors.

  • Depending on tissue of origin, cancer cells use various routes of glutamine metabolism; some require exogenous glutamine for malignant proliferation, whereas others do not and can synthesize it de novo.

    “Furthermore, depending on the tissue of origin, cancer cells use various routes of glutamine metabolism. Some have been shown to require an exogenous glutamine supply for malignant proliferation [71,72], whereas others do not [73] and can synthesize it de novo [74].”

    From HIF-1-Independent Mechanisms Regulating Metabolic Adaptation in Hypoxic Cancer Cells (2021) · cites this paper as [72]

    The Results section reports that glutamine is the main source of 2-hydroxyglutarate in two IDH-mutant chondrosarcoma cell lines, and that glutamine depletion greatly reduces its accumulation in one line. This supports glutamine-dependent metabolism, but the passages do not establish that exogenous glutamine is required for malignant proliferation. The separate claims about cells that do not require exogenous glutamine and synthesize it de novo are attached to other citations. (LLM, conf=0.79)

  • Generation of R-2-HG from glutamine occurs rapidly in patient-derived chondrosarcoma cell lines harboring endogenous IDH mutations.

    “Interestingly, the generation of R-2-HG from glutamine has been proven to occur rapidly in patient-derived chondrosarcoma cell lines harboring endogenous IDH mutations”

    From Glutamine reliance in cell metabolism (2020) · cites this paper as [121]

  • In IDH1/2 mutant cells, glutamine flux is directed toward R-2-HG generation, with kinetics similar to glutamate or α-KG formation via glutaminolysis.

    “In this study, glutamine flux was directed toward the generation of R-2-HG in IDH1/2 mutant cells, and the kinetics of R-2-HG formation were proportionally of the same order of magnitude as those of glutamate or α-KG formation via glutaminolysis.”

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.
