Across TCGA pan-cancer cohorts, RNU5E-8P RNA differs between tumor and matched normal tissue in 5 of 18 cancer types tested, making tumor–normal expression one of RNU5E-8P’s most consistent transcriptional readouts.
The strongest signal is observed in lung squamous cell carcinoma (LUSC), where RNU5E-8P RNA is repressed in tumor relative to normal tissue. In most cancer types RNU5E-8P is over-expressed in tumor, although a few such as LUSC and LUAD show the opposite, repressed pattern.
LUSC, LUAD, and BLCA are the cancer types where RNU5E-8P tumor–normal differential expression is most reproducible.
