Abstract

Proliferating tumor cells use aerobic glycolysis to support their high metabolic demands. Paradoxically, increased glycolysis is often accompanied by expression of the lower activity PKM2 isoform, effectively constraining lower glycolysis. Here, we report the discovery of PKM2 activators with a unique allosteric binding mode. Characterization of how these compounds impact cancer cells revealed an unanticipated link between glucose and amino acid metabolism. PKM2 activation resulted in a metabolic rewiring of cancer cells manifested by a profound dependency on the nonessential amino acid serine for continued cell proliferation. Induction of serine auxotrophy by PKM2 activation was accompanied by reduced carbon flow into the serine biosynthetic pathway and increased expression of high affinity serine transporters. These data support the hypothesis that PKM2 expression confers metabolic flexibility to cancer cells that allows adaptation to nutrient stress.

  • Activation of pyruvate kinase can inhibit cancer cell proliferation and tumor growth in some settings.

    “Indeed, activation of pyruvate kinase can inhibit cancer cell proliferation and tumor growth in some settings (Anastasiou et al., 2012; Kung et al., 2012; Walsh et al., 2010), but because pyruvate kinase expression is dispensable for the growth of some tumors (Cortes-Cros et al., 2013; Israelsen et al., 2013), whether pyruvate kinase activation will lead to durable responses remains an area of”

  • Activating PKM2 with small-molecule agonists increases PEP-to-pyruvate conversion, reduces flux of glycolytic intermediates toward anabolic pathways, and slows tumor cell growth.

    “Activating PKM2 by using small-molecule agonists increases PEP-to-pyruvate conversion, reducing the flux of glycolytic intermediates toward anabolic pathways and slowing tumor cell growth (56, 60).”

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.
