Abstract

Transcription of the human erythropoietin (EPO) gene is activated in Hep3B cells exposed to hypoxia. Hypoxia-inducible factor 1 (HIF-1) is a nuclear factor whose DNA binding activity is induced by hypoxia in Hep3B cells, and HIF-1 binds at a site in the EPO gene enhancer that is required for hypoxic activation of transcription. In this paper, we demonstrate that HIF-1 DNA binding activity is also induced by hypoxia in a variety of mammalian cell lines in which the EPO gene is not transcribed. The composition of the HIF-1 DNA binding complex and its isolated DNA binding subunit and the mechanism of HIF-1 activation appear to be similar or identical in EPO-producing and non-EPO-producing cells. Transcription of reporter genes containing the EPO gene enhancer is induced by hypoxia in non-EPO-producing cells and mutations that eliminate HIF-1 binding eliminate inducibility. These results provide evidence that HIF-1 and its recognition sequence are common components of a general mammalian cellular response to hypoxia.

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.
