Across TCGA pan-cancer cohorts, NPIPB1P RNA differs between tumor and matched normal tissue in 5 of 18 cancer types tested, making tumor–normal expression one of NPIPB1P’s most consistent transcriptional readouts.
The strongest signal is observed in colon adenocarcinoma (COAD), where NPIPB1P RNA is more highly expressed in tumor relative to normal tissue. In most cancer types NPIPB1P is over-expressed in tumor, although a few such as BRCA and KIRP show the opposite, repressed pattern.
COAD, LIHC, and KIRC are the cancer types where NPIPB1P tumor–normal differential expression is most reproducible.
