Abstract

Glutamate acting on N-methyl-D-aspartate (NMDA) receptors induces neuronal injury following stroke, through activation of poly(ADP-ribose) polymerase-1 (PARP-1) and generation of the death molecule poly(ADP-ribose) (PAR) polymer. Here we identify Iduna, a previously undescribed NMDA receptor-induced survival protein that is neuroprotective against glutamate NMDA receptor-mediated excitotoxicity both in vitro and in vivo and against stroke through interfering with PAR polymer-induced cell death (parthanatos). Iduna's protective effects are independent and downstream of PARP-1 activity. Iduna is a PAR polymer-binding protein, and mutation at the PAR polymer binding site abolishes the PAR binding activity of Iduna and attenuates its protective actions. Iduna is protective in vivo against NMDA-induced excitotoxicity and middle cerebral artery occlusion-induced stroke in mice. To our knowledge, these results define Iduna as the first known endogenous inhibitor of parthanatos. Interfering with PAR polymer signaling could be a new therapeutic strategy for the treatment of neurologic disorders.

  • ADPRHL2 and RNF146 prevent AIF release and consequent RCD by decreasing poly(ADP-ribose) levels and availability.

    “the poly(ADP-ribose)-degrading protein ADP-ribosylhydrolase like 2 (ADPRHL2; also known as ARH3) and the poly(ADP-ribose)-binding protein ring finger protein 146 (RNF146; best known as IDUNA) prevent AIF release and consequent RCD as they decrease poly(ADP-ribose) levels and availability, respectively [662, 668].”

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.
