Abstract

Glucose and glutamine serve as the two primary carbon sources in proliferating cells, and uptake of both nutrients is directed by growth factor signaling. Although either glucose or glutamine can potentially support mitochondrial tricarboxylic acid (TCA) cycle integrity and ATP production, we found that glucose deprivation led to a marked reduction in glutamine uptake and progressive cellular atrophy in multiple mammalian cell types. Despite the continuous presence of growth factor and an abundant supply of extracellular glutamine, interleukin-3 (IL-3)-dependent cells were unable to maintain TCA cycle metabolite pools or receptor-dependent signal transduction when deprived of glucose. This was due at least in part to down-regulation of IL-3 receptor α (IL-3Rα) surface expression in the absence of glucose. Treatment of glucose-starved cells with N-acetylglucosamine (GlcNAc) to maintain hexosamine biosynthesis restored mitochondrial metabolism and cell growth by promoting IL-3-dependent glutamine uptake and metabolism. Thus, glucose metabolism through the hexosamine biosynthetic pathway is required to sustain sufficient growth factor signaling and glutamine uptake to support cell growth and survival.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Glucose carbon is important to be metabolized through other branches of glycolytic metabolism, including serine synthesis and the hexosamine pathway.

    “It would also fit with the importance of glucose carbon to be metabolized through other branches of glycolytic metabolism, including serine synthesis (as discussed above) and the hexosamine pathway (Wellen et al., 2010).”

  • Glucose and glutamine collaborate in the hexosamine pathway to modify nutrient transporters and growth factor receptors, enabling their expression on the cell membrane.

    “But they also collaborate in another biochemical pathway to produce hexosamines, which modify nutrient transporters and growth factor receptors, enabling their expression on the cell membrane (Figure 2).”

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.
