Nuclear and mitochondrial conversations in cell death: PARP-1 and AIF signaling

Hong, Suk Jin, Dawson, Ted M., Dawson, Valina L.·2004·Trends in Pharmacological Sciences

Abstract

Different cell-death mechanisms control many physiological and pathological processes in humans. Mitochondria play important roles in cell death through the release of pro-apoptotic factors such as cytochrome c and apoptosis-inducing factor (AIF), which activate caspase-dependent and caspase-independent cell death, respectively. Poly(ADP-ribose) polymerase 1 (PARP-1) is emerging as an important activator of caspase-independent cell death. PARP-1 generates the majority of long, branched poly(ADP-ribose) (PAR) polymers following DNA damage. Overactivation of PARP-1 initiates a nuclear signal that propagates to mitochondria and triggers the release of AIF. AIF then shuttles from mitochondria to the nucleus and induces peripheral chromatin condensation, large-scale fragmentation of DNA and, ultimately, cytotoxicity. Identification of the pro-death and pro-survival signals in the PARP-1-mediated cell-death program might provide novel therapeutic targets in human diseases.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Even slower, sustained calcium influx through calcium-permeable AMPA receptors can be damaging through neuronal nitric oxide synthase activation, nitric oxide generation, and PARP-1 activation.

    “Even slower, consistent Ca 2+ influx through Ca 2+ -permeable AMPA receptors can be damaging via activation of neuronal nitric oxide synthase and generation of nitric oxide and resultant activation of Poly(ADP-ribose) polymerase 1 (PARP-1), (Fig. 1b), [109, 110].”

  • PARP-1 causes release of apoptosis-inducing factor through a nuclear signal that reaches mitochondria.

    “PARP-1 leads to the release of apoptosis-inducing factor (AIF) via a nuclear signal that proliferates to mitochondria [110].”

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.
