Across TCGA pan-cancer cohorts, P3R3URF RNA differs between tumor and matched normal tissue in 2 of 18 cancer types tested, making tumor–normal expression one of P3R3URF’s most consistent transcriptional readouts.
The strongest signal is observed in kidney renal clear cell carcinoma (KIRC), where P3R3URF RNA is repressed in tumor relative to normal tissue. In most cancer types P3R3URF is over-expressed in tumor, although a few such as KIRC show the opposite, repressed pattern.
KIRC and BRCA are the cancer types where P3R3URF tumor–normal differential expression is most reproducible.
