Abstract

Significance: Excessive activation of poly(ADP-ribose) (PAR) polymerase (PARP) is intimately linked to cell death in a variety of organ systems. It has long been thought that the cell death caused by excessive activation of PARP occurs through the catalytic consumption of NAD + followed by reduction of ATP and bioenergetic collapse. This study shows that the bioenergetic collapse is caused not by the consumption of NAD + but by PAR-dependent inhibition of hexokinase activity leading to defects in glycolysis. These results are consistent with the notion that cell death induced by excessive PARP activity (parthanatos) is an active cell-death program that is initiated by PAR signaling.

  • HK1 binding to poly(ADP-ribose) polymers inhibits glycolysis to cause a bioenergetic collapse that precipitates RCD.

    “hexokinase 1 (HK1), whose binding to poly(ADP-ribose) polymers inhibits glycolysis to cause a bioenergetic collapse that precipitates RCD [680, 681].”
  • Excessive PARP1 activation induces ATP depletion via PAR-dependent inhibition of hexokinase, causing dysfunctional glycolysis, likely independently of NAD+ depletion.

    “Notably, excessive PARP1 activation induces ATP depletion through PAR-dependent inhibition of hexokinase activity, resulting in dysfunctional glycolysis, a mechanism likely independent of NAD+ depletion (Andrabi et al., 2014; Fouquerel et al., 2014).”

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.
