Bioinformatics analysis of the TCGA database also revealed that, at the transcription level, RCN1 is positively correlated with NF-κB1 (RELA) and NF-κB2 in all collected cancer samples (Supplementary Figure S6a); these results indicate a positive correlation between RCN1 and NF-κB in cancer. Here, NFKB1 is linked to cancer.
