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; DNA: reporter gene construct; DNA: NF-kappa B DNA binding sites; protein: NF-kappa B; protein: NF-kappa B
Given options, please tell me the categories of all the listed entity words.Output format is "type1: word1; type2: word2".
