Of the 71 p52-associated genes, 35 were up-regulated in tumors (49.3%), indicating a significant over-representation of p52-associated genes in tumor samples compared to normal (hypergeometric test p = 6.0 × 10−25) (Fig. 4A,B and Supplementary Table S1) and suggesting that p52 could be important in human lung tumors. Here, NFKB2 is linked to neoplasm.
