Across TCGA pan-cancer cohorts, IMP3P2 RNA differs between tumor and matched normal tissue in 4 of 18 cancer types tested, making tumor–normal expression one of IMP3P2’s most consistent transcriptional readouts.
The strongest signal is observed in lung squamous cell carcinoma (LUSC), where IMP3P2 RNA is more highly expressed in tumor relative to normal tissue. In most cancer types IMP3P2 is over-expressed in tumor, although a few such as KIRC show the opposite, repressed pattern.
LUSC, BRCA, and COAD are the cancer types where IMP3P2 tumor–normal differential expression is most reproducible.
