Abstract

The major control point for the hypoxic induction of the vascular endothelial growth factor (VEGF) gene is the regulation of the steady-state level of the mRNA. We previously demonstrated a discrepancy between the transcription rate and the steady-state mRNA level induced by hypoxia. This led us to examine the post-transcriptional regulation of VEGF expression. Actinomycin D experiments revealed that hypoxia increased VEGF mRNA half-life from 43 +/- 6 min to 106 +/- 9 min. Using an in vitro mRNA degradation assay, the half-life of VEGF mRNA 3'-untranslated region (UTR) transcripts were also found to be increased when incubated with hypoxic versus normoxic extracts. Both cis-regulatory elements involved in VEGF mRNA degradation under normoxic conditions and in increased stabilization under hypoxic conditions were mapped using this degradation assay. A hypoxia-induced protein(s) was found that bound to the sequences in the VEGF 3'-UTR which mediated increased stability in the degradation assay. Furthermore, genistein, a tyrosine kinase inhibitor, blocked the hypoxia-induced stabilization of VEGF 3'-UTR transcripts and inhibited hypoxia-induced protein binding to the VEGF 3'-UTR. These findings demonstrate a significant post-transcriptional component to the regulation of VEGF.

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

  • The half-life of the mRNA encoding VEGF is more than doubled under hypoxic conditions, favoring angiogenesis.

    “By contrast, the half-life of the mRNA encoding VEGF is more than doubled under hypoxic conditions (334), again favoring angiogenesis.”

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.
