Activity of Protein Kinase RIPK3 Determines Whether Cells Die by Necroptosis or Apoptosis

Abstract

Life and Cell Death: Trying to protect animals from one form of cell death may lead to death by another. Two protein kinases, known as RIPK1 and RIPK3 promote signaling that leads to cell death by necroptosis. However, Newton et al. (p. 1357 , published online 20 February; see the Perspective by Zhang and Chan ) found that inhibition of RIPK3 was not always beneficial. Instead, mice expressing a form of RIPK3 with no catalytic activity died from increased apoptotic cell death, but animals lacking the RIPK3 protein entirely, did not die perhaps because RIPK3 restrains apoptosis mediated by caspase-8 by an independent mechanism.

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?

  • Pro-survival role of RIPK1 in development seems independent of both its kinase activity and RIPK3 binding, as mice expressing kinase-dead RIPK1 (e.g., RIPK1K45A) are viable and fertile.

    “Intriguingly, the pro-survival role of RIPK1 in development seems to be independent of both its kinase activity and RIPK3 binding, as demonstrated by the fact that mice genetically engineered to express a kinase-dead variant of RIPK1 (e.g., RIPK1K45A) are viable and fertile [447, 499, 508].”

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.
