Cellular and developmental control of O 2 homeostasis by hypoxia-inducible factor 1α

Open access

Abstract

Hypoxia is an essential developmental and physiological stimulus that plays a key role in the pathophysiology of cancer, heart attack, stroke, and other major causes of mortality. Hypoxia-inducible factor 1 (HIF-1) is the only known mammalian transcription factor expressed uniquely in response to physiologically relevant levels of hypoxia. We now report that in Hif1a −/− embryonic stem cells that did not express the O 2 -regulated HIF-1α subunit, levels of mRNAs encoding glucose transporters and glycolytic enzymes were reduced, and cellular proliferation was impaired. Vascular endothelial growth factor mRNA expression was also markedly decreased in hypoxic Hif1a −/− embryonic stem cells and cystic embryoid bodies. Complete deficiency of HIF-1α resulted in developmental arrest and lethality by E11 of Hif1a −/− embryos that manifested neural tube defects, cardiovascular malformations, and marked cell death within the cephalic mesenchyme. In Hif1a +/+ embryos, HIF-1α expression increased between E8.5 and E9.5, coincident with the onset of developmental defects and cell death in Hif1a −/− embryos. These results demonstrate that HIF-1α is a master regulator of cellular and developmental O 2 homeostasis.

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.
