Expression of IKKβ was not associated with cancer-specific survival (Figure 1A) (P=0.903), cytoplasmic p-p65 expression showed a non-significant trend towards shorter cancer-specific survival (Figure 1B, Table 2) (P=0.052) and nuclear p-p65 expression showed a significant association with shorter cancer-specific survival (Figure 1C) (P=0.042). Here, RELA is linked to cancer.
