Abstract

The p53 tumor-suppressor protein prevents cancer development through various mechanisms, including the induction of cell-cycle arrest, apoptosis, and the maintenance of genome stability. We have identified a p53-inducible gene named TIGAR (TP53-induced glycolysis and apoptosis regulator). TIGAR expression lowered fructose-2,6-bisphosphate levels in cells, resulting in an inhibition of glycolysis and an overall decrease in intracellular reactive oxygen species (ROS) levels. These functions of TIGAR correlated with an ability to protect cells from ROS-associated apoptosis, and consequently, knockdown of endogenous TIGAR expression sensitized cells to p53-induced death. Expression of TIGAR may therefore modulate the apoptotic response to p53, allowing survival in the face of mild or transient stress signals that may be reversed or repaired. The decrease of intracellular ROS levels in response to TIGAR may also play a role in the ability of p53 to protect from the accumulation of genomic damage.

  • TIGAR (C12orf5) functions in glycolysis by degrading fructose-2,6-bisphosphate, and thereby opposing the Warburg effect.

    “The TP53-induced glycolysis and apoptosis regulator, encoded by p53 target gene TIGAR (C12orf5), functions in glycolysis by degrading fructose-2,6-bisphosphate, and thereby opposing the Warburg effect.37”

    From Census and evaluation of p53 target genes (2017) · cites this paper as [37]

  • p53 regulates transcription of TIGAR and SCO2, which have key roles in glucose utilization and mitochondrial respiration.

    “This link has been strengthened by recent reports that p53 regulates the transcription of two proteins, TP53-induced glycolosis and apoptosis regulator (TIGAR) and the SCO cytochrome oxidase deficient homologue 2 (SCO2), which have key roles in the utilization of glucose and mitochondrial respiration, respectively 83, 84 .”

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.
