Regulation of AIF expression by p53

Abstract

The tumor suppressor p53 plays a pivotal role in suppressing tumorigenesis by inducing genomic stability, cell cycle arrest or apoptosis. AIF is a mitochondrial protein, which, upon translocation to the nucleus, can participate in apoptosis, primarily in a caspase-independent contexts. We now report that AIF gene expression is subject to positive transcriptional regulation by p53. Interestingly, unlike most known p53 target genes, the AIF gene is regulated by basal levels of p53, and activation of p53 by genotoxic stress does not result in a substantial further increase in AIF expression. The AIF gene harbors a p53 responsive element, which is bound by p53 within cells. p53 drives efficient induction of large-scale DNA fragmentation, a hallmark of AIF activity. Importantly, caspase-independent death is compromised in cells lacking functional p53, in line with the known role of AIF in this process. Thus, in addition to its documented effects on caspase-dependent apoptosis, p53 may also sensitize cells to caspase-independent death through positive regulation of AIF expression. Moreover, in the absence of overt apoptotic signals, the constitutive induction of AIF by p53 may underpin a cytoprotective maintenance role, based on the role of AIF in ensuring proper mitochondrial function.

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.
