In this report, we show that exposure of cells to hypoxia (0.02% O2) results in I kappa B alpha degradation, increased NF-kappa B DNA binding activity , and transactivation of a reporter gene construct containing two NF-kappa B DNA binding sites .
 ( protein: I kappa B alpha, None) , ( DNA: reporter gene construct, None) , ( DNA: NF-kappa B DNA binding sites, None) , ( protein: NF-kappa B, None) , ( protein: NF-kappa B, None)
