Abstract

Significance: The role of B-cell lymphoma-2 (BCL-2) ovarian killer (BOK) in apoptosis regulation has been a long-standing enigma. Despite the homology to BAX and BAK, BOK has yet to be linked to a definitive physiologic function in the classical apoptotic pathway. Here, we report a selective role for BOK in promoting mitochondrial apoptosis in response to endoplasmic reticulum stress.

Statistics

Recomputing p-values needs the paper’s full text.

Claims the paper makes

We couldn’t retrieve this paper’s full text, 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?

  • BOK contributes to the regulation of ER homeostasis, as demonstrated by its prominent localization at the ER membrane and the defective apoptotic response of Bok−/− cells to some ER stressors.

    “As for BOK, it has been proposed that this BCL2 protein contributes to the regulation of ER homeostasis, as demonstrated by its prominent localization at the ER membrane [149] and the defective apoptotic response of Bok−/− cells to some ER stressors [150].”

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.
