Abstract

Activation of glycolytic genes by HIF-1 is considered critical for metabolic adaptation to hypoxia through increased conversion of glucose to pyruvate and subsequently to lactate. We found that HIF-1 also actively suppresses metabolism through the tricarboxylic acid cycle (TCA) by directly trans-activating the gene encoding pyruvate dehydrogenase kinase 1 (PDK1). PDK1 inactivates the TCA cycle enzyme, pyruvate dehydrogenase (PDH), which converts pyruvate to acetyl-CoA. Forced PDK1 expression in hypoxic HIF-1alpha null cells increases ATP levels, attenuates hypoxic ROS generation, and rescues these cells from hypoxia-induced apoptosis. These studies reveal a hypoxia-induced metabolic switch that shunts glucose metabolites from the mitochondria to glycolysis to maintain ATP production and to prevent toxic ROS production.

  • HIF-1 actively participates in metabolic reprogramming from the TCA cycle to glycolysis by directly targeting the gene encoding PDK1.

    “Furthermore, Kim et al. provided the first evidence that HIF-1 actively participates in metabolic reprogramming from the TCA cycle to glycolysis by showing that HIF-1 directly targets the gene encoding pyruvate dehydrogenase kinase 1 (PDK1) (Kim et al., 2006).”

    From Therapeutic targeting of hypoxia and hypoxia-inducible factors in cancer (2016) · cites this paper as Kim et al., 2006

  • This metabolic adaptation is critical because of reduced entry of pyruvate into the TCA cycle by activated PDK1 and increased lactate secretion in hypoxia.

    “This metabolic adaptation is critical because of the reduced entry of pyruvate into the TCA cycle by activated PDK1 and the increased lactate secretion in hypoxia66.”

    From Glutamine reliance in cell metabolism (2020) · cites this paper as [66]

  • HIF-1 upregulates PDH kinase, LDHA, and other glycolytic genes to increase glycolysis, decreases TCA cycle activity, and reduces electron flux through mitochondrial complexes I, III, and IV.

    “HIF-1 coordinately upregulates PDH kinase, LDHA, and other glycolytic genes to increase glycolysis; decreases the activity of the TCA cycle; and reduces electron flux through mitochondrial complexes I, III, and IV (214, 386).”

    From Redox regulation of mitochondrial function (2012) · cites this paper as [214]

  • Low oxygen levels activate HIFs, which bind hypoxia-response elements in target genes including LDHA and PDK1, leading to suppression of PDHC activity and increased aerobic glycolysis.

    “For example, low oxygen levels activate the hypoxia-inducible transcription factors (HIFs), which bind to hypoxia-response elements within a number of target genes including LDH-A (LDHA) and PDK1, leading to suppression of PDHC activity with a concomitant increase in aerobic glycolysis (141).”
  • HIF1α stabilization by hypoxia or oncogenic contexts triggers coordinated transcriptional upregulation of LDH-A and PDK1.

    “Finally, stabilization of HIF1α by hypoxia or in various oncogenic contexts also triggers coordinated transcriptional upregulation of LDH-A and PDK1 (Kim et al., 2006; Papandreou et al., 2006).”

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.
