Across TCGA pan-cancer cohorts, NIPA2P4 RNA differs between tumor and matched normal tissue in 3 of 18 cancer types tested, making tumor–normal expression one of NIPA2P4’s most consistent transcriptional readouts.
The strongest signal is observed in lung adenocarcinoma (LUAD), where NIPA2P4 RNA is repressed in tumor relative to normal tissue. In most cancer types NIPA2P4 is over-expressed in tumor, although a few such as LUAD and THCA show the opposite, repressed pattern.
LUAD, HNSC, and THCA are the cancer types where NIPA2P4 tumor–normal differential expression is most reproducible.
