Comparison based on GO functional enrichment.

All predicted target genes of three NF-κB subunits were used for GO functional analysis. The enrichment level was calculated by transforming enrichment P values averaged over all processes with False Discovery Rate (FDR) corrected P<0.05. If no processes are found with corrected P<0.05, the smallest value of corrected P was taken for calculating the enrichment level. a p53 type refers to subgroups of HNSCC cell lines divided by p53 mutation: wt p53-deficient and mt p53. b enrichment of Fisher exact P value after negative log10 transformation. c FDR correction to the negative log10 value.
