In VivoExpression of mRNAs Encoding Hypoxia-Inducible Factor 1

Abstract excerpt

Hypoxia-inducible factor 1 (HIF-1) is a heterodimeric basic helix-loop-helix transcription factor that regulates genes whose products play key roles in maintaining O2 homeostasis. We have previously demonstrated that HIF-1 mRNA, protein, and DNA-binding activity are induced when mammalian tissue culture cells are subjected to hypoxia. In this paper, we report our analysis of HIF-1 mRNA expression in vivo. We...
