Abstract

Activation of the transcription factor NF-kappaB is a major effector of the inducible resistance to death receptor-mediated apoptosis. Previous evidence indicates that the combined transcriptional activation of TRAF-1, TRAF-2, IAP-1, and IAP-2 is required to suppress cell death by tumor necrosis factor (TNF). Here we show that NF-kappaB activation upregulates the caspase 8 inhibitor FLIP, resulting in increased resistance to Fas ligand (FasL) or TNF. Restoration of either the full-length 55-kDa long form of FLIP or an alternatively spliced short form of FLIP in NF-kappaB null cells inhibits TNF- and FasL-induced cell death efficiently, whereas the expression of IAP or TRAF family members only partially rescues cells from death. Resistance to either FasL- or TNF-induced apoptosis is overcome when cells are incubated in the presence of the protein synthesis inhibitor cycloheximide. This treatment leads to the rapid downregulation of FLIP but not to that of TRAF2. Our findings suggest that FLIP is an important mediator of NF-kappaB-controlled antiapoptotic signals.

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.
