Across TCGA pan-cancer cohorts, PRUNEP1 RNA differs between tumor and matched normal tissue in 1 of 18 cancer types tested, making tumor–normal expression one of PRUNEP1’s most consistent transcriptional readouts.
The strongest signal is observed in kidney renal clear cell carcinoma (KIRC), where PRUNEP1 RNA is more highly expressed in tumor relative to normal tissue. In most cancer types PRUNEP1 is over-expressed in tumor.
KIRC are the cancer types where PRUNEP1 tumor–normal differential expression is most reproducible.
